How to polish a tiny spot

Postby Don Burt » Sat Dec 03, 2016 1:03 pm

I get an occasional spot of crap on my otherwise clear glass. If I remove the crap with a little diamond bit, e.g. a 220 grit burr from HIS Glassworks, I now have a little white spot. Is there a way to polish this little speck so that I will have a little polished divot instead of a white dot?

use a razor blade.
won't leave a divot.
If the blade doesn't remove it so you cannot feel it, you have a problem!
If you worry about scratching, round off the corners of the blade first so it won't scratch.

If you have a tiny whitish spot after using a 220 grit burr. I found those rubberised polishing burrs messy, and hard to keep to a small spot. If you have a drill with a collet chuck, I love my foredom, you can use small wood or bamboo pieces in it with loose grit. 400 or finer then pumice or cerium. Matches or I get thin bamboo from sushi mats. Reason I prefer the collet is if it breaks it's easy to get the broken bit out. A bit of water, gently. If your drill has bigger collets, Foredom again, You can use 1/4 inch dowel shaped to a round end or a point. Very precise. (engravers can get anal over detail)

Don, could you paint something (a fig leaf?) over the offending spot and then refire?

Your artwork is usually very organic so modifying the design slightly might be a lot less arduous than trying to get back to shiny clear glass.

220 seems fairly aggressive (to me :) ). 800 grit burrs are easy to find. Diamond powder with a little carrier(oil) using the wood stick in drill(dremel) chuck is good for small round spots. https://lascodiamond.com/LascoProducts- ... owder.html A gram of diamond dust is about 1/2 a thimble full. Enough for a lot of spots.
*Many stores(especially those $1 stores) carry bamboo toothpicks - much strong than wood.
