Here are a couple more pictures. I do not have a picture of the final form, but the last picture below is the completion of the pick work – right before the air abrasion. I use 50 micron Sodium Bicarbonate on this matrix. occasionally, I will mix in a little Aluminum Oxide if the matrix is too hard.
