Lead Glasses
Hello All,

I'm thinking I'll start to dip my toes into the world of lead glasses. I have no idea where to start, I've usually steered away from lead for health reasons. But since I've started using selenium in my gold ruby (amazing results by the way, thank you Pete), I figure my self preservation has gone out the window. I'd imagine the best place to start for this would be a clear lead base. From there, could it be used with (hopefully) minimal modification to accommodate gold?

Gold colors always do best in a lead base. Always add a tiny amount of selenium to those melts. The hard part is getting the lead. These days, I see the bisilicate sold for $20 dollars a lb. I pay 98 cents for it in Shanghai. I can't import it. At this point here, I have about 350lbs of the monosilicate and the litharge left maybe a bit more and that will take me to the end of the line. I rarely melt it anymore.

Your health will be fine. Ventilate the facility well. wear gloves and a respirator. Jordan's little grow booth would work well.

I've heard melts with Pb do better in clay pots versus our typical alumina ones.
Any truth to this?

Clay is ideal but I've done lead melts in the High Temp alumina pots for years and it's fine. I doubt you would notice a difference in a smaller pot. What's important is controlling the atmosphere.
