    Anyway know how to make art clay copper? I love artcay copper but its only addviable in 50 gram pack.

    Unfortunately, no. A programmable kiln is required as you have to fire in a "reducing environment." This means that you have to limit the amount of oxygen that gets to your piece. Bronze and Copper have to be fired in activated carbon in order to produce this type of environment. Silver does not need to be fired with less oxygen present and can therefor be fired with a torch.

    Hi I made this and the clay was wonderful. But it didn't sinter. It crumbled like sand. Could someone tell me why?

    Hi Wiggins, I hope you make your next instructable soon, so we can all learn how to mix it and use it. Thanks.

    ​I bought all the ingredients, and the clay turned out beautiful. It was excellent to work with, ...But , the firing was a total flop. I have the Rio Grande kiln like you have in the video. Set the temp and held it for 2 hours and 22 minutes. The pieces crumbled like sand when I took them out. From what I have read, it means they didnt sinter...so back to the drawing board. Any suggestions Alan ? Did you have this problem at some point in your experimentation ?( PS thanks for sharing your metal clay knowledge :) )

    Pease Bryan. To_late2snooze at y hoo. Thx

    This is unbelievably helpful to someone who's interested in PMC but doesn't want to spend as much, thank you!
    How would you make it into actual clay? Adding water?

    I watched your video on YOUTUBE several days ago then I found you here.

    Have you tried to use any other inert other than Methyl Cellulose? I have found it to be quite expensive. Do you have a source, link to the 1lb container you referred to in your video? You can reach me at to_late2snooze at yahoo if you would.
