Henry,
That is not correct. Where did you get your info?

I have to say we got lucky with a short learning curve but we did have Nick's help. The first stuff that got melted at Penland was made to the orginal formula and which had no lithium. As I remember, the stuff was so hard to melt it got cooked at high temp for 24-36 hours perhaps the source of you stories. We were trying a relatively large grain local sand. We tried screening that sand to get a smaller grain but that didn't work. I remember only two people got some of those first runs. We tried changing the source of the sand and added the lithium at the same time and by the way it was the maximum amount suggested. We should have tried changing one thing at a time and used less lithium and then increasing it in a series of tests but that was not done. The result was the 92. We only took out a little soda to make the 87.
