After working with Argentium for a long time I wanted to melt sterling into ingots. However after trying many things and retrying with fresh sterling nothing works.
How I do it:
- reversible Durston mould
- oxy propane
- oil the mould and heat it up until it smokes
- preheat the crucible
- heat up the sterling silver and use the borax cone to flux it (I used borax salt as well in other tries)
- when it is molten and water like I pour it through flame
- separate the mould faces (it smokes) and I quench the ingot
The result…as in the attached picture (in other tries smaller and multiple bubbles present)
What am I doing wrong and what to change in this process?
