Thanks guys for all the advices i tried them all but porocity keeps coming it seem my metal is contaminated. A question again if you can help im using semi only because i cast nobel implants custable that has precious base. People told me that they use a non precious metal to cast and they dont have problems of merging the two metals. Do anybody know anything. I dont want to use semi precious any more and my doc likes nobel

Some photos of the problem would help. Also, what kind of blaster are you using and how much pressure? Have you tried different opaques? Does this happen with powder opaques? Oven entry temps? Does the metal have porosity? Dry time?
