Finishing white bronze

I need some help with finishing white bronze. I am fairly new at
casting.

The casting part I am ok with. My waxes are coming out better now. My
problem is really in the finishing of the product. Does anybody have
any tips to finish this metal. What tupe of tumbler should I use.
What to use to get the tarnish out ect. My customer is looking for a
nice polish for the least amount of $$$. That’s why I chose this
metal. Any help would be awesome. Thanks

Thanks,
Angie

using 2% Boron Copper Shot and adding about 1/2% of the total alloy.
It acts somewhat like a grain refiner and improves the finished
casting. Hope this helps and please let me know if you need anything
else.
