[QUOTE="Greencab77, post: 290095, member: 19923"] Hello to all! I appreciate everyone sharing in this forum. As our lab is transitioning to Initial MC from Synspar, it has been quite helpful. The first issue I’ve had is raising the oven temps enough that the opaque will stick to our non-precious metal,despite a 14.5 cte. How beneficial is the INmetalbond? I am new to paste opaques, so it could partially be in my technique. I’m certainly not getting full coverage in only two bakes! I’ve seen some references to lowering the starting temp of porcelain bakes. What are symptoms of having it too high? Also, is there a recommendation for vacuum strength? Our ovens fire Synspar at 725mm but I’m not sure where to set it for GC. Thanks in advance for any help! [/QUOTE]
