We Make Our Own Potassium Carbonate
Preparing the Solution
Potassium hydroxide flakes (KOH) are weighed and dissolved in distilled water, with quantities adapted for each batch size. The solution is mixed until fully dissolved.
Pouring & Room Setup
The solution is poured onto stainless steel trays, one or multiple depending on volume needed. The trays are left to react with atmospheric CO₂ at the day's natural room temperature and humidity.
Carbonation & Harvesting
As the solution sits exposed to the air, it slowly absorbs CO₂ and begins to crystallize. We watch for the first signs of crystallization, then decide just when to collect the material for optimal quality. Sometimes it’s 10 hours, sometimes a bit longer, each batch finds its own rhythm.
Combining, Checking & Storing
When harvesting, we collect all trays’ yields and bring different batches together. Every combined batch is titrated to confirm the concentration meets our standards.
Before final storage, each batch passes through a fine food-grade filter to ensure purity, and is sealed in airtight containers. The solution is now ready to be used in our soap recipes!
