32pcs Ceramic Firing Pegs for Crowns and Bridges in Porcelain Furnace

The price is great for dental lab,..and you get a whole bunch of them. They change color after the first firing,..oh well, no big deal. I use them for firing and glazing dental crowns. I like them a lot more than the metal pegs,..why? Crowns don't rotate if they fit snugly, so you can 'paint' them without too much ado. Only prob is, unlike with metal inserted posts,..they will slide off the firing dish if you aren't careful.Edit: well, OK...they change color dramatically when they are HOT, right out of the oven. Then come back to original color in about 15 mins. This is actually useful; you can tell when your 'bakery goods' are cool enough to play with. Take a look at my items I just took out of the porcelain oven. Neat, eh? (BTW, that white fluffy stuff under the crowns is SuperPeg II)
