Popular questions
How to remove calcium silicate from pool?
Calcium silicate scale is very hard and relatively acid‑resistant, so it’s typically removed by mechanical means (pumice/scale pads or bead blasting) after lowering pH and using a sequestering agent; an acid spot test that doesn’t fizz helps confirm it’s silicate, not carbonate. Prevent recurrence by keeping water balanced (pH/alkalinity/calcium) and using a sequestrant.
What is calcium silicate board?
A rigid, noncombustible building/insulation board made from calcium silicate hydrates, valued for fire resistance, moisture tolerance, and dimensional stability. It’s used for fireproofing, lining stoves/flues, and thermal or acoustic insulation.
How to cut calcium silicate board?
Score‑and‑snap works for thin sheets; thicker boards are cut with a circular saw using a carbide or diamond blade at a slow feed rate. Control dust with wet cutting or HEPA extraction and wear PPE (respirator, eye protection, gloves).
Is calcium silicate bad for you?
As a food additive (E552) used mainly as an anticaking agent, it’s considered safe at permitted levels (JECFA ADI “not specified”; FDA GRAS). The main concern is inhaling fine dust in occupational settings, which can irritate the respiratory tract.
Is calcium silicate vegan?
Yes—it's a mineral/synthetic ingredient with no animal-derived components, so E552 is generally suitable for vegans.
What is kaolin clay?
Kaolin clay is a naturally occurring hydrated aluminium silicate mineral (mainly kaolinite), used as the food additive E559 (aluminium silicate). It’s a fine, white, inert powder formed by the weathering of feldspar-rich rocks.
What is kaolin used for?
In foods (as E559), it’s used mainly as an anti‑caking and release agent in powdered products and as a processing aid; outside foods, it’s widely used in ceramics, paper, rubber, and cosmetics.
Where is kaolin clay found?
It occurs worldwide in deposits formed by weathering of granite/feldspar; major sources include China (Gaoling), the southeastern United States (Georgia), the UK (Cornwall), and Brazil.
How much kaolin clay per pound of soap?
A common usage rate is about 0.5–1 teaspoon per pound of oils (roughly 1–3 g per 454 g), pre-dispersed in a little water or oil; higher amounts can make soap feel draggy or more drying.
Is kaolin clay good for skin?
Cosmetic‑grade kaolin is a mild, fine clay that can absorb excess oil and add slip, so it’s commonly used in masks and powders; it’s generally well tolerated, but overuse may be drying—patch test if you have very dry or sensitive skin.
