Title: sodium silicate, liquid glass
Post by: travis on March 21, 2007, 09:11:50 PM

I've tried several methods to make a sodium silicate solution, none so far have worked as well as what you can buy in radiator stop leak. I'm putting recycled glass
in a small ball mill, grinding it very fine and mixing with NaOH. Does this reaction require heat as well. confused

You could try mixing molten silicon dioxide and sodium carbonate.
