Review on 🧪 Sodium Silicate Anhydrous (CAS) by Eastchem by Andrew Agarwal

I found and purchased this product based on the advertised CAS number 13870-30-9. I expected the product to be SODIUM TRISILICATE (Na2O7Si3), which is what that CAS number stands for. Instead, this product turns out to be ordinary SODIUM SILICATE (aka SODIUM METASILICATE) (Na2O3Si) with CAS number 1344-09-8. So if you're expecting to make your own class N water glass by dissolving it in water, you'll be disappointed as you'll end up with a class A water glass instead.
