These are my base numbers. Opaque, liner, shoulder 898 1min hold Dentine 892 1min hold 2nd 888 50sec hold Glaze 906 30 sec hold What I look for in dentine and glaze temps is a surface that has more glass than grain and that has sharp detail. To me this make me feel I'm not over firing and getting what the material has to offer. I spend a lot of time on contacts and don't want to affect them in final glaze. I use a thin mix of vita glaze-LT, not for a final surface by itself but to help achieve a surface I can hand-polish to a detail and luster for the situation.
