Is sodium silicate easily available? The beauty of EDR to me is that you can

Yes. I got mine from McMaster-Carr. As long as I was going through
the motions I got two jugs of it.

Just type "sodium silicate" (without the quotes) in the "Find" field
and you'll be given three choices, one of which is what you are

40% soldium silicate is $12.20 per gallon.
