Polishing Cab backs

You are not in the minority. Before I made my first cab, my wife collected them, so I got to study the work of many lapidarists.
A lot of different techniques. Some had polished backs and some didn't. Before I started to sell, I only polished the backs of some agates to improve the light from front to back. I don't usually polish the backs of jaspers. I have a very good customer who is a silversmith and wanted to buy a group of Blue Biggs and Deschutes and wanted the backs polished. I went through a period where I went from wax to superglue where I did all my work dopless. I polished the backs and one went flying off the wheel into the lost land. I found it a few months later when I was looking for another flying cab. My work area is on dirt so all flying cabs have a soft landing. I quit going dopless when I was working more regularly and was tired of the abrasions on my fingers.
I list all my cabs (unless they were made in the past with a polished back) as polished face with a sanded back.
