How to Torch Fire Prometheus Bronze Clay

[@lorahart56]

Good video Miss Carrie!

can you put it in water with stones settings?

[@pirikiki]

really helpfull

So the Prometheus clay I bought said torch firing will result in compromised bronze. It has to be carbon fired.

[@VickyGoodart]

the piece that your mentioned that was not fired properly, is that from too much heat or not enough? also i keep getting a mix of successful and unsuccessful pieces. Some just have a very dull and black speckle look no matter how much i polish, how can i correct that?

Would using some flux help prevent the oxide taking off that much of the bronze?

Had to "Google" sintering, but otherwise, great tutorial. It looked pretty orange the whole time during sintering. Assuming that's your camera or my monitor. Knowing to watch for cherry red helps. But is that while the flame is on the piece or just when you pull the flame away briefly for a quick peek? What about silver PMC? Have some I'd like to play with, but I'm just need to know what sintering color to watch for. What if your can runs out of gas before the sintering time is done, say 5-6 minutes in? Do you have to do the full 7 minutes for the bronze all over again or do you just finish the 1-2 more minutes once up to temp again? Close ups on the pieces would have been a huge help when you talking about whether the pieces were sintered properly. TFS!

It is important to note that only specific types of metal clay can be fired with a torch, please make sure to consult manufacturer recommendations for firing methods and times. To fire a metal clay project by torch, it is important to heat the project evenly; be sure to keep your torch moving so that the entire project glows. Working in a darkened area makes it easier to assess when you’ve reached a proper sintering temperature. When you begin firing, the project will flare up and produce flames as the binder burns off, after which the project will be a dull matte color until it reaches a suitable firing temperature. The exact color description may vary a bit, but a rich orange or light cherry red color should be visible throughout the project, and the project should “glow” this color. It is possible to over-fire a project, causing loss of detail or even altering the shape of the project as the metal becomes too liquid and flows or pulls in to become a smooth droplet. For this reason, aim for a lovely orange glow and maintain at that temperature while firing. If the color begins to glow “yellow” or the project begins to look shiny adjust to hold the torch a little further from the project.

I did everything as you said but my piece did not fire. This is the second piece this has happened with. Is it because I am not getting it hot enough and need a better torch?? How important is it to have more than 1 brick?? How important is the wire mesh. I have only 1 brick and no mesh wire???

[@333whiteraven]

Donna Sue You want to be sure you have a fire brick to distribute the heat properly. The mesh elevated is important to let the flame get underneath and create a flow of heat. I'm not sure why she said any brick will work. Other brick material absorbs heat, neutralizing your work underneath

I have failed over and over to get this right. Everytime, even with 10 min burn. It snaps and looks to not be done all the way through. So far I have had snapping peices and other that liquifies. They look fine, right up to the point you put pressure on them, then snap... :(
