Hello! New to the ceramic world and I am very interested in delving into Porcelain (cone 6) clay. I'm interested in designing very contemporary and minimal jewelry, however I understand that porcelain shrinks significantly during the firing process. My question is: how would I go about firing Specifically rings? are there certain metal rods that I could use in the kiln, similar to a bead rack that can keep the ring smooth and even during the process and POSSIBLY true to the size once finished? I've seen many of these beautiful rings online and I'm very unsure how to fire them. Also, is it possible to use PMC shrinkage stoppers like they use in metal clay ring design? PLEASE help as I'm very stumped on approaching this.. it would be very much appreciated! lost, Megan
I finally got around to making some of my own bead racks and what do ya know ... They actually worked! I have a couple commercial ones but they are just not in a configuration that works well for me and waste loads of room in the kiln. I made mine from the same clay I always use, Little Loafers. I am currently still using the nichrome wires from the commercial racks but when I have the money plan to buy some Kanthal wire and see how it works as supports for the items. The racks may not be beautiful but I have bisque fired them loaded as well as glaze firing with them loaded as you see in the pictures. I wasn't sure if the wires would sag too much without a counter balance on the outside points which I normally do but I needed the space to fire my spoons instead this time so I placed kiln posts along the tops and that seemed to work well also. The pictures show you the racks and also the racks loaded into the kiln. T
