It should not strike right from the pot. That would indicate the presence of fluorine. Since a phosphate is a phase separation glass it takes a cooling cycle followed by a heating cycle to cause that occurrence. The curiosity of the stuff Jordan made and I had noted to him privately was that it was streaky, something I didn't like. It looked like someones combed hair.
