A way that I have found for prepping metals prior to adding acids is to use:
1. Five gallon plastic bucket
2. A stainless steel mixing bowl that is a slightly less diameter than the bucket
3. a smaller stainless steel mixing bowl that when turned upside down will rest in the center of the larger mixing bowl
4. ice and water
What I do is fill the bucket up half way to a little more with ice. I add water til it's below the top of the bucket.
I then gently immerse the larger bowl and place it on the bottom of the bucket facing up. I then take the smaller bowl and place it upside down in the center of the larger bowel that is facing up.
I heat the metals up in my crucible and pour the metals with my torch on it til it drops out of the crucible , close to the surface of the water and in a circular motion in the center area.
The gold drops through the water, hits the upside down bowl and ends up in the larger bowl for retrieval .
Many ways to do this but for me I find this one works best for me-
