Our high-purity, eco-friendly, readily water-soluble lump glass is suitable for a wide range of applications.
At vanBaerle, potassium silicate lump glass is manufactured from potassium carbonate (potash) and silica sand in an electric furnace at a temperature of 1,400°C. The use of high-purity raw materials in conjunction with electrical energy instead of gas or oil allows the manufacture of a product with minimum contamination by means of a quasi-carbon-neutral process. This ensures a high dissolution rate of the glass in water and easy filterability of the liquid products during downstream processing.
vanBaerle manufactures potassium silicate lump glass with a molar ratio (MR) of 4.1.
Lump glass with other molar ratios can be produced on request. In addition to its applications as a base chemical for many liquid silicates, our potassium silicate lump glass is also suitable for use as a filler, e.g. in refractory mastics.
