we poured a lot of it down the radiators or T's, A's and flat-head
Fords to seal cracked engine blocks.  (Kids,, don't try this on your
dad's BMW)

More recently, while I worked at Porsche in the mid-1980s, we used it on the
assembly line to seal water-cooled cylinder heads (Porsche 944) if they didn't
pass the porosity test.

Plural might be better as there are a lot of them.

Actually a series of compositions with varying Na2O to SiO2 ratios and
various proportions of water.

Uses..... Catalysts, soaps and detergents, adhesives, sizing textiles
and papers, ore treatment, soil solidification and drilling muds,
binder for foundry cores and molds, water proofing mortars,
impregnating wood and I am certain that I missed a bundle of uses.

Chemical supply houses will have more mixtures than you will ever care
to know about.
