have you seen SS rated? I can imagine they various concentrations, going to google it.
That didn't take to long http://www.sodiumsilicate.org/liquid-sod...92771.html
I think we are using non alkaline or neutral is that what you use? i.

what I use is what ever the guy at the foundry downtown sold me, I know it has a high solids content an is thick as corn syurp. the stuff I got from a guy in tulsa isn't quite that thick and is clearer in color.

they both work the crap I got from the drug store that I was told would work that cost 24 bucks a quart wouldn't harden, nor would the junk that the ceramics shop sold me for 10 dollars a gallon that is used as a flocing agent in the slip.

I have been told by a guy that you can take that fancy cat litter and sodium Hydroxide and make your own.

of course if you like cookies you can get my ex to make you some biscuts that will outlast the cast iron I melt and pour.
