Try sandblasting with baking soda, much less abrasive. Cheap enough to try.

Interesting stuff ,,, Wouldn't practice with aluminum be cheaper and easier to see a result before casting the silver ... Free cans are all ova da place ...
Mans Quest for knowledge,,, means he'll always find a way !!
I have done casting in the past with aluminum. Cans are very impure and do not work well. Old car parts, aluminum windows, etc. work way better. Here is a video on doing it from a guy I follow. https://www.youtube.com/watch?v=FHADGpudizU
It would be cheaper but I plan on learning silver pouring might as well learn with what you are pouring. Plus you learn faster when you cost more.
I can keep remelting the silver so i am not loosing anything.
The temperatures are about 600 degrees difference aluminum melts about 1200 degrees and silver melts about 1800 degrees.
