Hey guys.
Im currently working with gold where i alloy my own 14 karat from fine gold…
@Shanaithal made me aware that i missed Zinc in my Gold / silver / copper equation, due to following reasons:
- (1) It’s a deoxidizer to protect the copper from getting oxidized during the melting and
- (2) forms a smoother casting surface.
- (3) Affects lowest permissible temperature, where Zinc will help further reduce the starting starting melt temperature.
Zinc addition will further reduce the starting starting melt temperature. - (4) Zinc additions significantly alter the yellow color of the 14K gold as well!
However, i am looking for a supplier within EU to sell this, since none of the Danish suppliers have Zinc on their shelves (Only premade alloys, gold, copper & silver), and neither have some of the ones abroad (UK) i usually shop at…
When i search online i get flooded with health supplements & plumbing materials.
Anyone know where to look for pure Zinc for casting within EU?
Best regards William
