Carrie Story, of Clay Revolution, teaches you how to torch fire your Prometheus Bronze Clay with a small butane torch. Visit www.clayrevolution.com for more videos!
Hi, thank you for the video. I have had no success firing bronze clay, which I am thinking is because my butane micro torch (which works for silver clay) does not have a big enough flame for bronze or copper. Can you please provide a specific link or name of the torch you use? I have looked online, but they don't specify what kind of flame they have, so I'm afraid I might end up buying the same type of torch I already have. Thank you!
Can't we torch fire the prometheus Troy bronze clay in any way? I just order and didn't notice in the description it says it can't be torch fired! I'm cryigg!! :'( :'(
Can you please tell us specifically what torch do you use? I tried several ones and I find it impossible to torch fire it, no matter how long I try or how orange is the piece. thx
Hello! I use a butane torch head with a large nozzle. It is not a brand name and is very inexpensive. Here is the link to it. clayrevolution.com/butohe.html You buy purchase more expensive ones at most of the jewelry supply sites. However, this one does the trick for me. The key is that the nozzle must be bigger than the micro butane torches.
anyone got any tips? help! I have tried torch firing with a large butane torch at a red/orange colour for 14 minutes and my piece shattered when I put it in cold water and it had only partially sintered. I'm using sunny bronze Prometheus. it just won't work! the instruction manual said fire for 5 to 10!! wtf! but that didn't work either. I pickled and brushed what was left just to test and there was a slight bronze sheen but it totally fell apart. argh planning help! thx
Hi Lorri, I'm sorry, I never got the notice of your post and just now saw it. I will be happy to explain. Sintering is when the metal particles are partially melted together. It is a range of level of melting, not a specific point. They can be barely stuck together, or stuck together very well. A torch fire, will always produce a minimal level of sintering. It will not be strong enough to bend, but can be used effectively for most things. As an example, I never recommend that my students torch fire rings (no matter the clay/metal). The finished piece of metal is not as strong as a high level of sintering would produce. Torch firing will limit the types of items you can make. However as a beginner, you will have a better understanding of what is happening to the metal by torch firing. This can allow you to have much better results both torch firing and kiln firing.
I tried the instructions exactly as provided using Prometheus sunny bronze but I am just getting black oxide which won't come off. Does anyone have any advice please ?
Does it have to be bone dry ? I brought some and made a ring out of it and let it dry over night in a warm room and fired it the next day and it was very brittle and broke apart in my hand
Hallo, was kostet mich ein Stück runtergerechnet in euro? Also was sind die Herstellungskosten c.a für ein Ring oder ein Armband oder Ring in normaler Größe.? Ist das kalkulierbar oder haben sie da Erfahrungen?
i'm torchfiring Goldie Bronze Clay. If i try to sinter it w i t h o u t excluding oxygen (as per one of the videos here where she uses a carbon bed inside a kiln) the stuff just turns to black oxidised cinder which crumbles in your hand. If i exclude oxygen with a coating of silver clay the bronze fuses properly --- so the prob is oxygen. But i don't want to always need to use silver coating, natch. Does anybody know how this lady manages to sinter with torch in open air without excluding oxygen and yet achieve proper result?
Hi! The key to the torch firing is that flames suck in oxygen. So, use a large bushy flame and that will be an oxygen reducer. However, you need to get it to the water to quench quickly so the oxygen doesn't attack it when you take the flame off.
Thanks, yes i know about the quenching thing --- just logical --- but i was talking about the bronze turning to cinder throughout the piece. However it is not linear --- sometimes yes sometimes no with no apparent pattern. Damned frustrating considering the work time invested in a piece.. but erm .. not to whine, eh.
I like your video but when showing your examples we can't really see them! You need to have the camera to zoom in. The examples only work if we can see them.
+valeriaorl77 Prometheus® White Bronze Prometheus® White Bronze must be fired in a kiln and has a multi-step firing schedule, much like other base metal clays. It has a shorter firing temperature range than Prometheus® Bronze, meaning that there is a much more specific target heat and hold combination you’ll need to reach for proper sintering. Fire only a few pieces of white bronze at a time, and place them in the very center of the kiln. Pieces placed towards the edges of a kiln may not sinter fully. Generally, there will be a Phase 1 firing, which is open shelf and burns off the binder. Phase 2 firing is in carbon, and will sinter the white bronze. The final phase is a quick open-shelf firing to anneal the metal. Manufacturer’s Directions Phase 1: Pre-ramp the kiln to 932ºF. Place pieces on steel mesh and put into the hot kiln for 10 minutes. Cool. Phase 2: Put a 3cm layer of activated carbon on the bottom of a steel container. Place pieces with at least 1.5cm space between each other and fill the container with carbon. Fire to 1420ºF for 2 hours. Allow pieces to cool in carbon. Phase 3: Anneal the pieces by heating to 1050ºF for 5 minutes, then quench in cool water.
+Jamie Huntley thank you Jamie I wrote to prometheus customer care and they told me the same thing. I'm disappointed because when I bought withe bronze from perles and co the description says thet can be torch fired. I'll will wait untill I can afford to buy a kiln :(
