Potassium Nitrate and Antiquity Glass
« on: February 07, 2019, 10:35:38 AM »
A little goes a long way. I add about 2g into 250g of powder. Others just sprinkle it on straight or roll it in a bit. The effect is dramatic and creates smoking and bubbling on the piece. Nitrate helps in the batch melt so consider this a catalyst or flux for localized glass melting. Silver nitrate also does this a bit but is obviously gobs more expensive. Very fun...I have overdone it and seen some cracking due to incompatibility. Everything in moderation  8)
