The long journey of zeolite
What is zeolite? – Briefly explained
Zeolite is a natural mineral group formed millions of years ago when hot volcanic ash met water. Over very long periods, a crystal lattice of silicon and aluminum tetrahedra formed, crisscrossed by millions of tiny pores and channels.
- Name: from Greek zein (to boil) and lithos (stone) – coined in 1756 by mineralogist Axel Fredrik Cronstedt
- Structure: porous, highly ordered crystal framework with a huge internal surface area
- Property: can absorb, bind, and release water, ions, and certain substances
- Most important variety for us: natural clinoptilolite zeolite – one of the most well-researched natural zeolites
- Use: e.g. agriculture, animal husbandry (approved as a feed additive in the EU), horticulture, plant care, cosmetics, and technology
In short: an inconspicuous stone with an extraordinary inner architecture – shaped by fire, water, and a lot of time.

Fire. Water. Time.
There are stones you walk past carelessly. We build houses or paths with them and hardly give them a thought.
And there are stones that make you pause. Not because they sparkle. Not because they are rare. But because they tell a story. Zeolite is one of these special stones for us.
The longer we deal with it, the more our respect grows. Because zeolite is not a product that man invented. It is the result of nature taking its time. A lot of time.
While we humans think in years, the earth thinks in millions of years. Perhaps that's where the fascination begins.
Nature knows no hurry
We live in a world where everything is supposed to get faster. Grow faster, produce faster, function faster.
Nature does not know this hurry. An old tree does not grow faster because we wish it to. Fertile soil does not form in a few months. And zeolite did not form overnight either. Its story begins long before humans existed – deep inside the earth.
It all began with fire and water
Millions of years ago, mighty volcanic eruptions hurled glowing ash and rock high into the atmosphere. Part of it fell back to land, another part was absorbed by the sea. There, the enormous heat met cold water.
Fire met water. Heat met calm.
Under pressure, with water, and over very long periods, new minerals formed from this volcanic ash. One of them is zeolite – not in days, not in centuries, but over time spans that exceed our imagination. Layer by layer, year after year, million years after million years.
Its name still describes this origin today. The Swedish mineralogist Axel Fredrik Cronstedt coined it in 1756 from the Greek words zein (to boil) and lithos (stone). When he heated the mineral, water emerged from its fine pores – the stone seemed to boil.
Thus the name Zeolite – the boiling stone was born.
The patience of the Earth
Perhaps that is the greatest wonder of zeolite. Not its pores, not its crystal structure, not its extraordinary properties – but the patience with which the earth allowed it to form. While we humans often seek quick solutions, zeolite reminds us that some things simply take time.
The memory of the primeval seas
After the volcanic ash had settled in the water, a journey began that no human could observe. Over millions of years, mineral-rich water flowed through the fine cavities of the developing rock. It brought salts, minerals, trace elements – repeatedly, slowly, ceaselessly, not as a one-time event, but as an infinitely long natural process.
Sometimes we imagine that zeolite still carries a memory of this time within it. Not in a human sense, not as memory, but as an expression of its origin. Its fine cavities still tell of the mineral-rich primeval seas from which it emerged.
Perhaps that is why we feel such great reverence when we hold a piece of natural clinoptilolite in our hands. Not because we are looking at an ordinary stone, but because we are touching Earth's history.
A masterpiece of nature
From the outside, zeolite appears inconspicuous: light, dull, calm. Nothing suggests that within it lies a world that has fascinated scientists for centuries. Perhaps this is another lesson from nature: the most valuable things are often not on the surface.
Under the microscope, zeolite suddenly begins to tell a completely different story. What looks like ordinary rock to the naked eye reveals itself as a highly ordered crystal framework with millions of tiny channels and cavities that run through the mineral like a three-dimensional labyrinth. These cavities did not arise by chance – they are the result of millions of years of development.
Its crystal lattice follows a precise geometric structure of silicon and aluminum tetrahedra. In between are the characteristic cavities and channels containing, among other things, calcium, magnesium, sodium, and potassium.
This special structure has made zeolite interesting for science, agriculture, and technology for decades. It allows it to absorb, release, or store water, ions, and certain substances – depending on the application. Perhaps that is precisely why zeolite is so versatile. Not because it "magically" does everything, but because its structure is extraordinary.
Not all zeolite is created equal
Many people simply speak of "zeolite". In fact, zeolite is not a single type of rock, but comprises an entire mineral family with numerous natural and synthetically produced variants. Today, far more than fifty natural zeolite types are known, in addition to numerous synthetic variants used, for example, in industry.
For our work, natural clinoptilolite zeolite plays a particularly important role. Not because other zeolites are worse, but because it has been intensively researched for decades and is one of the most well-studied natural zeolites worldwide. Today it is used, among other things, in agriculture, animal husbandry, horticulture, and various technical applications. When we speak of zeolite, we therefore almost always mean natural clinoptilolite.
Nature cannot be copied
"It's all zeolite anyway" – we view this statement more critically. Just as not every wine tastes the same and not every forest soil has the same composition, no two zeolite deposits are alike. Each has formed over millions of years under different geological conditions: different water, different minerals, different temperatures, different pressures. As a result, composition, purity, clinoptilolite content, and properties differ. Zeolite is therefore not just any raw material, but always a piece of its landscape.
Can a stone be organic?
Again and again we encounter terms like "organic zeolite" or "zeolite in organic quality". These terms often cause confusion. A stone does not grow in a field, it is not sown, not fertilized, and not organically cultivated. Zeolite is a natural mineral. Therefore, we deliberately speak of natural zeolite or natural clinoptilolite zeolite – a mineral that nature itself has produced.
Why quality means more to us than an analysis sheet
Of course, laboratory analyses, purity, limit values, controls, and careful processing are all part of it. But for us, quality begins much earlier: with the selection of the deposit, in gentle extraction, and it doesn't end with the finished product, but with responsibility towards people, animals, soil, and plants.
Especially with zeolite, for example, particle size plays a crucial role – not everything that looks fine is actually fine, and not every grinding method equally utilizes the possibilities of this special mineral. But we would like to tell you more about that elsewhere.
The longer we work with zeolite, the less we think of numbers when it comes to quality. For us, quality begins with respect: respect for a natural mineral that took millions of years to form, respect for the people who will later use it, and respect for the responsibility not to treat such a gift of nature as ordinary merchandise. Perhaps that is precisely the difference between a raw material and a natural product. A natural product deserves attention.
One mineral, countless possibilities
The deeper we delved into the history of zeolite, the more often we asked ourselves the same question: How can a single natural mineral be used in such different areas – in agriculture, animal husbandry, gardening, plant care, cosmetics, and even technical applications? Is this a coincidence, or is there something common connecting all these areas of application?
We believe: Nature knows no categories. A forest does not produce oxygen because it has understood it as a task. Soil does not store water because someone obliged it to. Nature acts according to its own order, and often several effects arise simultaneously. Perhaps this is also the case with zeolite – not because it is a jack-of-all-trades, but because its natural properties can be used in different areas, always adapted to the respective application. Sometimes it's about water, sometimes about ammonium, sometimes about odors, sometimes about nutrients, sometimes about a fine mineral layer on a leaf. The application changes, the origin remains the same.
In agriculture
In the field, it's primarily about one question: How much of what we put into the soil actually reaches the plant? Water and nutrients that quickly seep away or are leached out benefit neither the field nor the environment. Zeolite can help here: Its porous structure binds water and nutrients in the soil and releases both over a longer period, instead of being lost unused.
This is particularly interesting on light, sandy soils that naturally have little storage capacity, but also on intensively used areas that have lost structure and storage capacity over the years. This is also why natural clinoptilolite plays a role in many areas of agriculture today – not as a substitute for nature, but as part of a larger whole that helps the soil to better utilize its own abilities again.
In animal husbandry
In stables and feeding, zeolite shows several facets. Natural clinoptilolite is used in the European Union as a technological feed additive to optimize feed and is approved for all animal species.
Furthermore, it is used as a bedding additive for stable hygiene, for example, where its ability to bind ammonia or ammonium can contribute to a better stable climate.
A better stable climate is more than just a more pleasant smell.
Less ammonia in the stable air means less irritation of the respiratory tracts for animals and humans, drier bedding, and overall more hygienic conditions.
Fewer udder inflammations, more milk to deliver, healthy hooves, more animal welfare.
For horses
Horses accompany us at STEINKRAFT in a very special way – as sport partners, as leisure companions, often as full family members.
At the same time, they now lead a life that has little in common with that of their wild ancestors: less movement on natural ground, altered feeding rhythms, often many hours in the stable. And their bodies have new challenges to overcome. Pollutants in hay, water from lead pipes, etc.
In this environment, zeolite is used on several levels. As bedding or box additive, it can help bind moisture and ammonia, keeping the box drier and noticeably improving the air quality – a point that is often brought up, especially for sensitive horses with respiratory problems. As a technological feed additive, natural clinoptilolite can also contribute to optimizing the feed.
For us, the exchange with horse owners is particularly valuable because horses react very sensitively to their environment. Those who work with them daily often notice small changes faster than any measuring device.
For dogs
For us, dogs are also far more than just another application area. They live closer to us today than ever before: in the apartment, in the car, in the office, on holiday. With this close coexistence, the expectations for a healthy and long dog life also grow.
In feeding, natural clinoptilolite is used as a technological feed additive to optimize the feed. Many dog owners are also interested in zeolite for everyday use in fur and skin care.
In the garden
In your own garden, the versatility of zeolite shows itself in a completely unique way. Mixed into flower, vegetable, or pot soil, zeolite can help retain water and nutrients longer in the root zone, instead of both simply seeping through the soil with every watering or rain.
Especially in sandy or depleted soils that can hardly store anything, this is noticeable: The soil remains consistently moist, and nutrients are available to the plant over a longer period.
Zeolite is also readily incorporated for soil improvement in beds or raised beds. Its porous structure loosens heavy, compacted soils and simultaneously creates tiny cavities where soil life, roots, and water can come together.
In potted plants, where the root space is naturally limited, such an admixture can help maintain a more stable delicate balance of moisture, air, and nutrients.
For us, the garden is a good example of how directly one can experience the effect of natural processes. You see the earth, you see the plant, you see how both react to changes. Perhaps that is also why so many hobby gardeners are interested in zeolite: it is a simple, tangible way to give the soil back some of its natural storage capacity.
In plant care
Beyond the soil, zeolite is also applied directly to the plant. When finely ground, it can be used as a component of foliar applications, forming a wafer-thin mineral layer on the leaf. This layer changes the plant's surface in a way that is valued in practice, for example, with regard to weather influences or the plant's general resistance or as a physical repellent.
In cosmetics
In external applications, many people value its special properties. For example, as an ingredient in masks, scrubs, or powders.
Its fine, porous structure makes it interesting for applications where moisture absorption or a pleasant skin feel are important.
Here, too, we are not focusing on the promise of a miracle cure, but on the inherent properties of this natural mineral – the same porous architecture that makes it so versatile in the field, in the stable, and in the garden.
As diverse as these applications are, they all have one thing in common: they do not rely on artificially created functions, but on properties that this mineral has carried within it for millions of years.
Nature always works in context
A healthy soil influences the plant. The plant influences the animal. The animal influences humans. Humans, in turn, influence the soil. Everything is interconnected. This perspective has accompanied us since our founding – which is why we rarely talk only about products, but rather about cycles: about soils, animals, plants, and humans.
Soil is much more than earth. It stores water, retains nutrients, is a habitat for billions of microorganisms, and connects roots with fungi. Regenerative agriculture therefore does not begin with fertilizer or machinery, but with the question: How can we support the soil in unfolding its natural processes again?
Anyone who has lived with animals for a long time also knows: They often react more subtly than we do and follow their instincts rather than product descriptions. Over many years, we have had countless conversations with farmers, horse owners, dog owners, and veterinarians – the same question always came up: How can we accompany animals as naturally as possible? Not with ever new miracle cures, but with a mindful look at feeding, housing, and living environment.
Plants also tell stories: You cannot force a plant to grow, you can only provide light, give water, improve the soil, and be patient. The rest the plant does itself.
All life seeks balance
The longer we observe nature, the clearer a pattern emerges: It strives for balance. A forest tries to grow again after a storm, a stream finds a new way after every obstacle, a healthy soil always develops new life. None of this happens by force or compulsion.
Physiologist Prof. Dr. Karl Hecht described this ability as the self-regulation of the organism: Every cell, every organ, every living organism constantly tries to maintain or regain internal order. Perhaps this is precisely one of nature's greatest wisdoms – not in perfection, but in the constant striving for harmony. We cannot create these processes or command them. At most, we can create conditions under which life can do what it always tries to do on its own: unfold.
That's why we don't see zeolite as a miracle cure, not as a shortcut, not as a substitute for nature. But as an extraordinary natural mineral whose properties constantly remind us how much wisdom lies in natural processes.
Why a million-year-old mineral is more relevant today than ever before
It's actually astonishing: a natural mineral that originated millions of years ago is experiencing new attention precisely today. Not because zeolite was suddenly rediscovered – rather, it's our perspective on the world that is new.
We live in a time of extremes. Our soils are expected to yield higher returns. Dairy cows produce many times the milk of earlier generations. Arable land must feed ever more people. Gardens are expected to flourish despite dry periods. Our dogs accompany us into old age, travel with us and share our daily lives; horses today also lead a completely different life than their wild ancestors – they have become sport partners, leisure companions and family members. The demands on plants, animals and soils have grown, and at the same time our expectations are rising: everything should be healthy, sustainable, natural and resource-efficient.
Perhaps this is the real challenge of our time: nature itself has not fundamentally changed – but we demand significantly more from it today. This is neither good nor bad, it is simply the reality of our time. And that is precisely why it is worth looking more closely at natural interconnections again.
Sometimes nature is talked about as if it constantly needs correcting. We see it differently: We don't want to replace natural processes, but to support them. Soil remains soil, an animal remains an animal, a plant remains a plant. Our task is to create conditions under which their own abilities can develop as well as possible.
In recent years, the term regenerative agriculture has become increasingly well-known. For some, it's a new buzzword, for us, it describes an attitude: not just to use soils, but to maintain their long-term fertility, build up humus, better store water in the soil, promote soil life, and strengthen nutrient cycles. Because every fertile soil is more than just a production area – it is a habitat.
Nature rarely works with spectacular leaps. A little more organic matter in the soil, a little more water retention capacity, more active soil life, a better stable climate, balanced feeding – many small steps together often lead to astonishing development. Perhaps this is precisely the greatest strength of natural solutions: they do not rely on one major intervention, but on many small improvements that complement each other.
Perhaps this also explains why natural minerals like zeolite are once again moving more into the spotlight today. Not because they have become modern, but because we have begun to rediscover old connections.
A stone that teaches us humility
My father often spoke of the primeval energy of zeolite. A few years ago, that word sounded mysterious to me. Today I understand it differently: perhaps primeval energy is not a mysterious force at all, but describes the original state of nature – a state where everything is still connected. Fire, water, air, earth. None of these elements fights against the other, each fulfills its task, everything works together. Over millions of years, a mineral thus came into being that did not have to mature under time pressure. It was simply allowed to become. Perhaps that is its true primeval power – not something supernatural, but a reminder of how nature works if you let it.
He once said something I will never forget:
"Material is thrown from the fire of the volcano into the air, lands in the water, and thereby becomes boiled stone. When it is then tribomechanically ground, it remembers its primeval forces and provides the energy of fire, air, water, and earth."
Whether one views this thought scientifically or philosophically is up to each individual. For us, it describes something essential: Zeolite is much more than a raw material. It reminds us how much power lies in natural processes if we are willing to understand them instead of trying to control them.
Why we still can't let go of zeolite today
There are products that accompany a company for several years. And there are products that become part of its own history. For us, zeolite clearly belongs to the second group.
We have been working with this extraordinary natural mineral for many years. We have read studies, talked to scientists, accompanied farmers, discussed with veterinarians and animal owners, and received countless feedback from customers. And yet there is one sentence that we still cannot utter: Now we know everything about zeolite. On the contrary - the more we learn, the greater our curiosity becomes.
Every answer leads to a new question
At first, we wanted to understand how zeolite originated. Then we were interested in its crystal structure, later the grain size, the deposits, the mineralogy, the grinding processes - and the question of why natural clinoptilolites from different regions differ. In addition, there were studies, experiences from agriculture, and feedback from dog and horse owners.
And again and again, we noticed: As soon as we thought we had found an answer, the next question arose. Perhaps that is precisely what is so fascinating about genuine nature. It can never be fully explained.
Nature is greater than our knowledge
In our time, there is a temptation to want to measure and explain everything, to demand an immediate and clear answer for everything. Of course, science needs precisely these questions, and we value scientific research very much - it helps us to better understand nature. But sometimes we also believe that nature is greater than our current knowledge. Not mysterious, not magical. Simply greater. Perhaps in ten or twenty years, science will be able to explain some things that we only suspect today. That's how it has always been, and it will probably remain so.
Between science and experience
That's why both have always been important to us: careful studies and people's experiences – not as opposites, but as complements. When farmers make similar observations over many years, we listen. When animal owners repeatedly describe the same experiences, we take it seriously. When scientific studies explain connections, we are happy about it. And if something is not yet sufficiently researched, we say so just as openly. This honesty is part of our responsible approach to nature.
Humility is part of it for us
Perhaps the word humility is somewhat out of fashion today. For us, it is inextricably linked to nature. A person can sow a seed, but the plant must grow itself. A farmer can care for his soil, but life does not arise at the push of a button. An animal owner can create the best conditions, but every animal remains its own being. This realization does not diminish us. It makes us more grateful.
If someone asks us what we appreciate most about zeolite, our answer today is different from ten years ago. Back then, we would probably have talked about minerals, crystals, and pores. Today, we would say: Zeolite has taught us to look more closely again – at the soil, at plants, at animals, at natural connections, and perhaps also at ourselves. Because those who spend a long time with nature eventually realize: It is not nature that must constantly change. But our view of it.
A journey that is far from over
We do not believe that we have reached our goal. On the contrary: With every new study, with every new experience, with every conversation with farmers, veterinarians or customers, our knowledge grows a little further. That is why we do not understand STEINKRAFT as a company with ready answers, but as people who are willing to keep learning – with an open mind, with respect for science and with the same enthusiasm for nature that has accompanied us from the beginning. Because perhaps that is the greatest strength of nature: It never stops showing us something new.
Why we are still enthusiastic about zeolite today
The longer we work with zeolite, the less we see it as a miracle cure. And that's precisely what makes it so fascinating for us. It reminds us that nature has developed its own solutions – long before modern technologies existed. Perhaps we don't need to reinvent them. Perhaps we just need to learn to look more closely again.
When we look back at our work today, we see not a collection of individual products, but a common thread: a natural mineral, a soil, a horse, a dog, a tomato plant, a piece of arable land, a handful of compost. Everything initially seems different – and yet they speak the same language. The language of life. A language that does not speak of haste, but of cycles. Not of perfection, but of balance. Not of control, but of trust.
Perhaps that is precisely why this special mineral has accompanied us for so many years – with the same fascination as on the first day. Because perhaps nature already knows what we humans sometimes forget: All life already carries the desire for balance within itself. And perhaps our task is not to constantly try to improve nature, but to better understand it again.
Frequently asked question
Why is zeolite on everyone's lips now?
1. The trend towards natural products is growing stronger. We also want to take more preventive measures. Especially feed, if stored for a long time or delivered from far away, is contaminated with pollutants and molds, mycotoxins and whatever else they are called. Animal owners are becoming more mindful.
2. Meat producers are becoming more transparent, and if they want to work more naturally, transparency is essential.
Feed optimization is a very affordable way to support animal welfare here. And of course, raising awareness about climate change.
Zeolite binds methane. This harmonizes and supports digestion and microbiology, e.g., in cattle, and at the same time makes an important impact on the climate.
3. Zeolite can help detoxify and revitalize soils.
It activates the ion exchange capacity in the soil.
For nutrients to be easily found by roots, this communication needs to be stimulated.
Zeolite can do that. That deserves a separate blog post.
4. The demand for nutrient-rich foods is growing louder. Zeolite can provide plants with many trace elements and thus make a good contribution.
Have you ever seen Zeolite under a dark-field microscope?
There are moments when science and wonder coincide. For me, this is one of them.
When you look at STEINKRAFT Zeolite under a dark-field microscope, you don't see gray particles. You see crystals that seem to glow from within. Structures reminiscent of snowflakes. Living geometry. Life.
Perhaps this is the most beautiful proof of what my father means: This mineral remembers its primordial powers. You can see it if you look closely.
If zeolite fascinates you as much as it fascinates us, you can find more information about its origin, properties, and applications on our knowledge page about zeolite.
