Thanks, Janet
I’ve read that. However, my understanding that sandblasting would produce a uniform finish. The finish on Beth pieces is not uniform, so I an thinking, rolling mill is used? Also for oxidation - how would you achieve very uniform light gray color and how would you protect it wearing off when you rub your jewelry against your clothes constantly, especially rings?

Since sandblasting is usually done with a homogeneous blasting medium (sand with all the grains the same size), it usually produces a uniform finish. But imagine sandblasting using a blasting medium with all different size grains…
-
You get a uniform, light gray color by oxidizing, brushing with a glass brush, and repeating the process until you get the desired shade and evenness. This is just one of many ways. I use it on shiny metal when I want a sheen rather than a shine.

Jewelry is usually renewed for a photo shoot and for exhibiting. A shiny ring will be carefully polished and thoroughly cleaned. Likewise, any sort of surface treatment which may have worn off with wear will be refinished before shooting or showing.
