Q. Are sodium metasilicate ⇦this on eBay or Amazon [affil links] anhydrous and sodium metasilicate pentahydrate [affil links] interchangeable for mixing with other products?

A. Hi Anthony, The pentahydrate is 42 percent or so water and only 58 percent or so sodium metasilicate. So the formulations have to be approximately halved or doubled. There might be other effects that need to be taken into account depending on the actual situation.
