I had a fire polish program that I liked, but it was for other colours of glass, and a little top-fired kiln, so I've been having difficulty getting it right these days. I'm firing in kiln 7, which I'm used to, and it seems to fire to the temperatures that I tell it to which is nice, but my normal 600 degree celsius isn't working the way it normally does (yeah, I know that's very low, but I like things velvety.) So I've tried with higher temperatures for 10 min at a time. I'm happy with 650, and 660 is good too, at least for the clear/white combination I've been using. Here's 10 min at 640:
