I had a bell from the CS Bell Co sandblasted and had the same pits. I was curious to know if this was a condition of the firing process when the bell was originally made. There were imperfections in the yoke that seemed to have been filled wtih some type of putty perhaps before the bell was originally painted at the factory. Since the imperfections on the surface of the bell did not appear until after the sandblasting I wondered if the same material was used to give the bell its smooth appearance after painting. Obviously the sandblasting process removed the paint and as a result the filler material.

I have not found any information about how the bells were treatoed before painting, nor have I found any indication yet of what substance they might have used to fill in these imperfections.
