Hi, can anybody suggest where might sell or manufacture bead rods that go to cone6/7. Currently using bead rods you find commercially, usually made of nichrome and so when reaching temps of over 1200 they tend to start sagging and releasing green/black deposits into the kiln - usually I have kiln shelves covered in black soot by the end of a firing. I use kanthal wire which has solved a green deposit problem I had on the clay when using nichrome, but for the life of me can't find anywhere to replace the kiln rods with higher firing ones! I'm UK based.
birdypotter posted a topic in Studio Operations and Making WorkI use nichrome wire hooks to hang decorations no larger than half the size of the palm of your hand and no thicker than 5mm, though often a lot smaller and a lot thinner. I've been using hooks as the decorations are fairly heavy and so I use thick bead rods - too thick to thread directly through the holes made in the clay. (If anybody could suggest a better method I'm open to making my life easier, bending 100 pieces of wire and hanging takes a lifetime!) The wire itself is sturdy and doesn't slump, however I use a white stoneware body, decorated and transparently glazed. After a stoneware glaze firing (I glaze to 1250) I have what I can only describe as green burn marks above the area where I've cut the hole, right where the wire sits, though the wire does not touch the piece. I thought it might be the wire getting old, it can become quite black and brittle after several firings. However after replacing it with new wire I have the same problem on the first firing. I can't remember it being a problem I've always had, and I've tried several different clays recently in a sampling run - it's happened with all of them, so just trying to rule things out. It's ruining what would otherwise be completely saleable work and I'm totally confused! I really hope I'm missing something obvious here; can anybody shed some light please!?
