Technical specifications
What is in the bottle, and what we can prove.
Independent elemental analysis, physical properties, safety testing and regulatory position. Where a value is still to be published we say so rather than rounding it into a claim.
Elemental analysis
What the laboratory measured.
Independent analysis of the finished product as sold, on an as-received basis. Values below a method's reporting limit are shown as such rather than rounded into a number.
| Analyte | Symbol | Level found | As % | Notes |
|---|---|---|---|---|
| Quantified | ||||
| Sulfur | S | 2,600 ppm | 0.26% | Dominant constituent by mass. The extraction acid leaves the metals in sulfate form, which is why sulfur tops the assay. |
| Nitrogen (total) | N | 800 ppm | 0.08% | Present in trace only. See the note below on why this matters. |
| Iron | Fe | 430 ppm | — | Electron transport in cytochromes and ferredoxin. Central to the redox chemistry and to the solution's optical signature. |
| Calcium | Ca | 400 ppm | 0.04% | Cell wall structure and root development. |
| Magnesium | Mg | 200 ppm | 0.02% | The central atom of every chlorophyll molecule. ATP reactions, enzyme activation, membrane stability. |
| Below the reporting limit of this method | ||||
| Phosphate | P₂O₅ | <1,000 ppm | <0.10% | Reporting limit 0.10%. |
| Potash | K₂O | <500 ppm | <0.05% | Reporting limit 0.05%. |
| Boron | B | <100 ppm | — | Reporting limit 100 ppm — too coarse to quantify a trace constituent. |
| Sodium | Na | <100 ppm | <0.01% | Below detection. Relevant for irrigation: this adds no meaningful sodium load to soil. |
| Manganese | Mn | <20 ppm | — | Reporting limit 20 ppm. |
| Zinc | Zn | <20 ppm | — | Reporting limit 20 ppm. |
| Copper | Cu | <20 ppm | — | Reporting limit 20 ppm. |
| Silicon (acid soluble) | Si | <10 ppm | — | EPA 6010. Reporting limit 10 ppm. |
Heavy metals
Nine metals screened. None detected.
Analysis by EPA methods 6010 and 7471, sample prepared by EPA 3050b. Analytical chemistry can demonstrate absence only to a threshold, so each result is reported against the reporting limit of its method rather than as an absolute zero.

The mother solution
Every product on this site is a dilution of one solution.
Themarox is the concentrated mineral extract produced by Shimanishi Kaken in Japan. Aurmina and Primora Bio are not separate formulations — they are that same solution, diluted. Across its certificates of analysis, twenty-nine elements have been individually measured. How that number is built.

The method
How we arrive at twenty-nine measured elements.
Every element below has been individually quantified by an accredited laboratory on a certificate of analysis. None is inferred, estimated, or carried over from a claim about the source rock.
- 25
- Quantified in the mother solution. Shimanishi Kaken commissioned Clearize Co., Ltd. to assay Themarox itself. Thirty analytes tested, twenty-five returned values: Al, Ca, Ce, Co, Cr, Cu, Fe, K, La, Li, Mg, Mn, Na, Ni, P, Rb, S, Sc, Si, Sr, Ti, V, Y, Zn, Zr.
- + 4
- Resolved in the retail product. Selenium and barium sit just under the mother solution's reporting limits — a sample that concentrated must be heavily diluted to be read, which raises the limits with it — and are measured cleanly in Aurmina, where the sample is weaker and the limits are finer. Boron and silver were not on the mother solution's analyte list at all, and are quantified on the retail panel by EPA 200.7.
- = 29
- Distinct elements individually quantified, across thirty-two analytes tested on two certificates.
- Not counted
- Germanium, tungsten and molybdenum. Tested, not detected on any panel. They are excluded from the twenty-nine.
Why it takes two certificates. Themarox, Aurmina and Primora Bio are one solution at three strengths. Each is tested by whichever laboratory produced it, on whichever method that laboratory runs, at whichever reporting limits that method carries — so each certificate sees a slightly different slice of the same chemistry. We could have published whichever single list ran longest. Instead we publish the union of what has actually been measured and show the arithmetic that gets there, so you can check it. The geological literature documents more than forty distinct elements across biotite and closely related trioctahedral micas — and that figure is a floor set by detection limits and by the panels investigators chose to measure, not a complete inventory of the rock.¹ ² In 2007, Eric Moeller, then president of The Vermiculite Association, put the potential inventory as high as eighty.³ Twenty-nine is what has been measured here, and twenty-nine is what we claim.

Physical & chemical
Product properties.
- Appearance
- A clear to gold-colored aqueous solution.
- Composition
- 99% purified water, 1% ionic mineral salts.
- Form
- Ionic — the elements are dissolved and complexed in solution, not suspended as particles. UV-Vis absorbance confirms dissolved transition-metal complexes rather than suspended solids.
- pH, as supplied
- Not yet measured. The raw extract is strongly acidic and the finished product is heavily diluted from it, but we have not run pH on the bottle as sold and will not publish a figure we have not taken. It will appear here when we have it. In the meantime two handling rules stand. Do not tank-mix with high-pH inputs — lime sulfur, Bordeaux mixture, hydrated lime, potassium silicate — which drop the minerals out of solution. And do not run it into a line during acid injection, where sulfuric, phosphoric or urea-sulfuric acid puts a very low-pH stream through the system.
- Shelf life
- Indefinite. It is a mineral solution — it does not degrade, expire, or lose potency.
- Storage
- Sealed, at room temperature. No refrigeration required.
- Compatibility
- Drip, sprinkler, pivot, flood and hydroponic systems. Tank-mixes with most fertilizers, amendments and biological inputs; apply high-pH inputs such as lime sulfur or Bordeaux mixture in a separate pass.
- Source mineral
- Weathered volcanic biotite mica, selected because it carries a broader range of elements than almost any other rock.
- Extraction
- Sulfuric acid leaching, which frees the elements and leaves them predominantly in sulfate form.
Safety
Heavy metals and synthetic content.
Heavy metal screening
Below detection limits
Full-panel ICP-MS screening for lead, cadmium, mercury, arsenic and thallium returned no detectable quantities. Stated precisely: below the detection limit of the method — analytical chemistry can demonstrate absence to a threshold, never absolutely.
Synthetic content
No synthetic additives
The product contains no artificial additives, preservatives or synthetic nutrients. The elements are drawn from volcanic rock using sulfuric acid as the extraction reagent, so we describe it as naturally sourced and minimally processed rather than as a natural product.

- Full report
- Available on request. Ask for it — we would rather you read it than take our summary for it.
- Extraction method
- U.S. Patent 4,776,963, granted 1988 to Asao Shimanishi and co-inventors, covering a method of purifying water. The patent records that the method was novel. It is not evidence that the product performs, and we do not present it as such. It has since expired.
