Sodium silicate

[Joe]

I'm just wondering if anyone has experience using sodium silicate (waterglass). If so, I'd love to hear about it.

Just ordered a sample for another project of mine.
When I get it, I plan to also try a separation experiment:
Remember those magic crystals ads in the back of old comic books? Want to see if my waste solutions will separate into different colored products.

Joe, were you wanting it for a binder of sorts in a homemade refractory mix?
I found a recipie for this is why I ask.
