Here's my 2 cents: Disclaimer: I'm no expert at this and others may have better methods, but you'll know what the bits look like. I always submerge the item being drilled in cool water. Watch out when the hole breaks through, as the drill bit can pop through quickly and the drill end may break the pot (probably not an issue with a drill press). The pot on the left was drilled with the diamond tip, the one on the right with the glass/tile bit. Hey, where'd that stinking little slug come from, lol?? The bit on the left is for masonry drilling. You can tell by the little 'wings' on both sides. It takes a loooong time to drill through pots with this. The two in the middle are glass/tile bits. They do a pretty good job. I start with smaller ones and work up to the larger ones, so the larger ones don't get dull from the initial drilling. They work pretty well. The bit on the right is a diamond tip bit. It pulls water into it as it's spinning to keep it cool. It drills a 'plug' out of the pot. It seems to work the best and will be the only one I use from now on. Be sure to read the package about how to start a new hole by drilling at an angle. This may not be necessary with a drill press. Here's the top end of the diamond bit. I've never drilled glass, so can't speak to that. It's probably a good idea to keep your bits cleaner than mine, lol. Hope this helps. Linda

I see them advertised for huge prices but I think a more realistic price may be $40.00 to$80.00 , maybe you could consign it to a antique shop and get more, who knows.They are few and far between now just my opinion.

I'll bet the ladies on the mosaic forum will have a good answer for you. I know some of them have nippers and saws even. Would love to see your wall pocket project when you get it finished. Luvs

What a nice collection. I always drool over the ones with roses on them, but that blue and white one is a really nice pattern and shape too. The yellow one looks like it is trimmed in gold--very nice. Bet you enjoy finding new ones to add to your collection. So nice that you have lots of storage space. I first became interested in them when I visited my BIL's cousin. She had special display shelves on the walls in her kitchen and the cups and saucers looked so pretty on them. I don't have much room, but I have started hanging some plates with roses on my wall. Have three plates and several saucers so far. Gives me something to hunt for when I hit the TS or YS's. Love it when I find one--get excited just like Christmas! Ha ha Thanks for taking and posting the pics. I really enjoyed seeing them. Luvs
