  1. The rim has three different glazes on it. I'm interested in the area below that, which had a nutmeg glaze that I wiped off. It remains in the grooves, and is mostly gone in some spots. The sweet spots are partially wiped off, but not totally removed. So, any way to get that look without wiping off glaze? Thanks!
  2. I like the look of this mug where the glaze is partially wiped off. It's a nice darkened red sheen. Is there a way to get a similar look without the waste? On some pieces a smoother sheen would be preferable. Is there something for cone 6 that would produce this nice toasty look?
  3. Thanks, Chris, I'll stick with the Frost and try to figure out another way to attach the wire.
  4. One reads about high-tech super tough ceramics, but maybe those are all press formed and sintered. I'm just up the mountain from Coors, that might be an interesting tour. They probably don't tour the ceramics side tho.
  5. Either clay body seems to break like glass after firing. The earwire is stainless, and I often break the connection point even if I try to shield it from any torque. The closed spirals would ride on a chain, but I fear they would break if the hit a desktop or something.
  6. I'm looking for a tougher clay body for jewelry, basically less brittle and breakable, for cone 6 firing. I've tried B Mix and Frost Porcelain, but both are quite fragile in my designs. I'd love to make earrings from them, so they can't be much thicker, thus heavier. Are there additives that would help? I'm extruding these designs, so long fibrous material might not work. I'm into experimenting, however, so please offer any ideas.
  7. Potters don't let other potters drink Coors. PBR, yes. Coors brothers are evil, they support some truly nasty organizations. I'd still buy their rods, tho. No place else to get them.
  8. We really have a problem with the wires sagging and oxidizing and flaking off at cone 6. I found some really nice "ceramic" rods at CoorsTek, order online, here:http://css.coorstek.com/scripts/css512.wsc/op/op_indexB2C.html#65982 about 1 mm thick, or 18 gauge, goes to a very high temp, would probably last forever unless you dropped them, about $10 each for 8 inches. All good, except there is a $150 minimum order. Shucky darn.
  9. Thanks, Joel. I will not try titanium. The Kanthal A1 looks great: Kanthal A-1 (Resistance heating wire and resistance wire)A ferritic iron-chromium-aluminium alloy (FeCrAl alloy) for use at temperatures up to 1400°C (2550°F). Kanthal A-1 is characterized by high resistivity and very good oxidation resistance. I've been mostly finding thin gauge wire used for vaporizers, lots of that going on here in Colorado. I'll keep looking for heavier gauge rod. I suspect it will be expensive, otherwise they would be using it for the standard bead rack I bought. Greatly appreciate your wisdom.
  10. Has anyone tried titanium rods for bead racks? The standard rack that I bought has rods that sag and get a green and black coating after firing at cone 6. The coating can flake off onto the pieces below. Cone 6- 1222 C and 2232 F, titanium melts at 1668 C and 3034 F. That doesn't mean that the rods won't sag or react with the atmosphere inside the kiln though... Oh wise ones, please share the knowledge.

    High-Tech Ceramic

    I'm looking for something similar, for earrings that won't shatter if you drop them. In my previous life as a jeweler, I came across a material in watches that had a glossy or matte finish that seemed to hold up really well, did not scratch or shatter. I'm in Colorado, and I know that the evil Coors company has a sideline in ceramics, I think they worked on the space shuttle tiles. I haven't found much info, there are some expensive books, like this one on Amazon: An Introduction to the Mechanical Properties of Ceramicswhich look interesting, but are very technical. I suspect that some of these materials are made by sintering, compressing and heating powders to form a solid, way beyond our abilities. It does seem likely though, that there may be a way to strengthen clay somewhat. Have you found out anything else?
