Right before our local studio tour, I make up a couple of hundred of these type pendants To hand out to people who come through. I Tell them to pick a token of our appreciation for there visit. The stamps I use are based on local native American pictographs.  The kids especially like them.  I just use a colored wash and wipe it off, then fire them all in a pile. Never had a problem with sticking since they are not glazed.

Having test fired one or two of the pendants, you know in advance how badly this particular underglaze melts and sticks to alumina, itself and other kiln stuff stuff.

Lakeside Pottery commented online that many or most commercial underglazes blister-off clay when fired, we too were annoyed by the way . Because of this our studio transitioned to 2/3 Gerstley Borate with 1/3 Mason Stain as an underglaze. Colors, other then Black, Gray or Taupe, have an additional 17% zircopax added. The gerstley borate is mixed with water and sieved before adding color to each restaurant style squeeze bottle.

If your underglaze sticks to stuff and you want to suspend them, use old kiln element wire, or buy new Kanthal wire (which is Nickel, Chrome, Aluminum element wire) preferably something like thick like 20 guage or even 13 gauge.

Like element wire, this thick gauge will soften and sag in the kiln, so a test ahead of time will show you how far you can run the wire between supports. As kiln elements the concept is the aluminum near the wire surface oxidizes, protecting the interior of the wire.

Many glazes are very corrosive to Kanthal wire, just as they are to kiln elements. If your glaze is corrosive, the Kanthal wire will be brittle after the firing and will be a one time use.

I have a bunch of pendants and small tiles I've made,I used commercial under glaze on them. My question is how do I do a single firing of them? Some are glazed front & back :)

on these only the oxide b/c I will be laying them on top of each other in the kiln.  They stick together a little during the fire but separate as they cool without any problems or marks afterwards.  I have glazed some previously, front and back and suspended them on a high temp rod.  Those I use to make necklaces, key fobs, zipper pulls, etc.

Nice project... Do you do any other glazes on them or just the oxide?
