New to casting, needing guidance in casting a pewter ring Mar 25, 2016 15:19:59 GMT -5 Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by htbmonsters on Mar 25, 2016 15:19:59 GMT -5 Greetings! I'm new to casting metal, but not with creating molds/models--but up to know it's all been one-part molds done in plaster for non-jewelry items.I've begun a project carving and casting a ring in pewter and would love some advice!Starting info:- I'm using R98 pewter for the casting (92% Tin, 7.75% Antimony, 0.25% Copper)- Under recommendation of other casters, I'm using Mold Max 60 RTV silicone instead of plaster/lost wax- The ring itself has a very basic band, flat top, and simple carved design on the face consisting of basically four straight lines (easy details to capture, I'm hoping)- I'm experimenting with using both green and purple Matt carving waxes for sculpting the ring- I've been using sculpey to mount the ring in the mold vessel/create the sprue spaceQuestions:1) Should I be using plaster/lost wax? From what I've read this may be needlessly complex for my simple design/needs2) Should I be using a single part mold of some kind? Or a two-part mold with the break oriented around the circumference of the ring? This second method is what I've been experimenting with.3) Should I be using a different material for the mounting/sprue/air ducts in the mold? The sculpey seems to hold up well enough, but I know wax/wax wire may be more standardly used.
