Don't ever burnish a byzantine chain
If you're referring to tumble-burnishing chains with stainless steel
media, I tumble sterling and gold-filled chains all the time and
I've never had a problem! I have a Raytech vibratory tumbler, mixed
stainless shot and I just add a squirt of blue Dawn and let it go.
The chains always come out super shiny and I've never had any
problems with tangling or binding.
