There are a few people using Sodium silicate so it does make good glass
So the person that Pete just mentioned having a bad experience with in his last class would claim that he or she can get away with lower melt temps because of starting with the sodium silicate mix in a homemade batch. If that's accurate, then I'd be curious, Ron, about your melt and working temp which seem higher than most I think. Does your mix have a higher viscosity that needs the higher gathering temps?
