Afternoon,
Help please !!! I make pmc fingerprint, hand print jewellery and have always hand finished the pieces using polishing papers. My work load has increased so I have just purchased a 3lb tumbler from cookson with mixed steal shot and burnishing powder. I put a batch of items that had been fired and wire brushed into the tumbler, I checked the items every hour and they didn't ever reach that super mirror finish I was expecting. I tumbled them for 8 hours in total and then gave up. The finish was almost pitted and wondered if the pins from the shot caused this. I would really appricate advice on this and recommendations of timings and processes etc.
Many Thanks
Lucy.
