Hi there,
Just wondering what some of your recommendations are for full gold crown investment materials. I am currently using Sherafina 2000. It is a wonderful investment material for substructures, so no complaints there. Gold restorations however, tend to come out fairly rough and takes a bit of work in terms of finishing. My expectation is to see a smooth surface (as per waxup) after it has been cast.
Also, do you treat your wax patterns for gold casting with something before investing it?
Thanks!
