[QUOTE="Patrick Coon, post: 196909, member: 11366"] Are you thoroughly drying your units in a drying oven or under a heat lamp before sintering? This is very important to avoid cracking. Single units 30minutes @ 80C, Bridges up to 4 units 2hr @ 80C, Long span/Full arches at least 4hrs @ 80C. As for touching up the anatomy with a FG diamond, USE LOTS OF WATER! If you are seeing them "light up" then you are going too fast/applying too much pressure. [/QUOTE]
