Pressing glass, porcelain and metal into pottery
Hello,
I'm looking for advice about the feasibility of pressing other materials into greenware before firing and there's a bunch of questions I have. First, is it possible, or do the different contraction rates make it impossible? I live close to a beach that my wife and I lovingly call Tetanus Beach, because it is completely covered with rusted metal, rounded pieces of glass and shards of porcelain. All quite beautiful. If I ever did get past the biscuit stage of firing, is there any chance of it being functional ware, or would it only be decorative? And if it is possible, is there any treatment (like sterilizing) of the materials required, or does firing to ^6 kill any nasties that may be lurking? Any advice or past experience with this type of thing would be greatly appreciated. Thanks. Simon |

Any advice or past experience with this type of thing would be greatly appreciated. Thanks. Simon Simon: I have a friend (a fellow potter) who puts pieces of broken stained glass into a depression he creates while throwing a bowl (the depression is in the center of the inside bottom, not the outside). He says that the glass melts nicely into a puddle and fuses to the bowl. He has even had some success in lifting the kiln lid quickly and stirring the glass with a metal rod to swirl it while it is molten. (He might be doing that during raku, rather than regular firing. Sounds like a recipe for disaster to me, but the results are beautiful. I always wondered why he had no eyebrows :) No idea what he uses for clay or glaze, so in that, you are on your own. I just know that it's possible. Hope that helps, Wayne Seidl |

Ceramic shard?? impossible to know what temp they were first fired to. I suggest you look into the learning the technique of mosaic. You could still make your own pots and mosaic found items after. |

I place pieces of broken wine / sherry bottles into the bottom of bowls,
blues and greens work well. I fire to cone 9 and it melts well, cone 6 is a bit too low a temperature and the glass looks like melted plastic. Different glass has different melt temps just like glaze (its a similar material) so its best to keep it contained inside a bowl when firing. When the bowl cools it contracts at a different rate to the glass to you get crazing, which is very affective.... but don't use the bowl for liquids / food. Regards Kevin. wrote in message . ..
