I have all of the equipment to investment cast gold silver and platinum but I have not used it for 2 decades.
Casting in investment is a lot of work compared to lead molds but it is cleaner and more controlled.
I was just hashing around with my girl friend about the silver bullet thing and it got me wondering how many on the fire have tried it.
Thanks for the info. If I do some I will do them the jewelers way.
Wax is the way to go. My stuff is about 20/25 years old also.
Was fun to buy gold back in the day, make a mold, then cast.
Did find out I was one bad artist. Liked the tech more than the design.
