Q. Are sodium metasilicate anhydrous and sodium metasilicate pentahydate interchangeable for mixing with other products?
Anthony Natalini - Oneonta, N.Y. U.S.A.
A. The pentahydrate is 42 percent or so water and only 58 percent or so sodium metasilicate. So the formulations have to be radically altered at the very least. What other effects need to be taken into account is hard to say from this distance.
