[QUOTE="HonestAbe, post: 340789, member: 25390"] So I'm relatively new to casting (only a few years experience) and realizing that I've been getting by alright but when things don't go well (miscast, porosity, investment problems) I don't have a strong foundation in the fundementals to troubleshoot what's going on. I don't really have anyone that can look over my shoulder and point out what I'm doing wrong. I get the sense that I'm doing most things correctly but there's so many variables that sometimes a combination of things adds up to me messing something up. The areas I perceive I'm weakest at are: Getting my torch set correctly for different alloys Optimal sprue technique I'm just wondering if anyone has some resource they can point me at to read up or watch where I will hopefully notice things I am doing sub optimally. Most of what I cast are full gold crowns, with the occasional pfm, custom abutment, or post. EDIT: I suppose I could also start documenting stuff with photos so we can laugh the next time I mess something up and hopefully figure it out, but for now I'm mostly just looking to read and study something to see if anything jumps out at me.
