[QUOTE="Wyolab, post: 172018, member: 1394"] I agree, a lower temp for longer will probably leave you a cleaner press. Is that 1600 Fahrenheit? If so that would be about 870 Celsius. Marcus are your temps in Celsius or Fahrenheit? My pressing oven is Celsius and my burnout oven is Fahrenheit, so I burnout at 1565f and peak pressing temp is 910c. I use scheinvest and with a 100gram ring I use 16ml liquid 8ml h20 and place in the hot oven at 1565f after 20 minutes for one hour before pressing. I don't do bridges without a zirconia frame though. I used shofu for a while and had less of a reaction layer. [/QUOTE]
