If you are making leaf ash for glazes...........

Recommended Posts

In Japan it is somewhat typical for many potters to burn various plant materials to make pure ash (of various types) for use in glazes. Some western potters do this also. Brother Thomas did this for a lot of his glazes.

 

I saw this item and thought..... hum.... nice idea.

There are several videos on YouTube by gindaup (Gary Navarre) about a burner made from bricks he calls a Koie Cooker after the Japanese potter, Ryoji Koie, that showed him how to build and fire it.

I haven't tried it, but it seems like it would work. It is not as sophisticated as the stainless steel one, but I doubt it woul cost $349 plis shipping either.

That BurnCage is genius. Thanks for sharing John. It's a bit expensive though and, living in Europe, I can't order it from drpower. I will search the web if I can find something similar here in the old world....:D

Well I imagine you COULD order it... but the shipping would require a mortgage. ;)

 

However, if you don't go with stainless.... you can maybe fabricate one from cheaper materials. The stainless is nice because it does not add much iron scale though.

 

The IDEA is pretty sweet.

 

best,

John,

 

If you have a lot of brick laying around...... it is just the cost of the construction time. And note that you can make these using red brick also. The temperatures you hit don't actually require firebrick. And certaily low duty firebrick are more than adequate for this too.

 

If you bought new HD firebrick for building that "Giant" one Gary shows... it likely would cost well MORE than the stainless one ;) .

I just had an idea, now someone tell me why it won't work, lol. I was thinking, couldn't you put a sagger full of leaves (or whatever you want to make ash from, and just put it in a bisque firing? Or is the volume too low to make it worthwhile? Or, would it fuse too much?

I think if one rummaged around a recycled materials shop there would be a selection of grates and registers, etc to fabricate a burn box yourself. The dr company is a past client of mine from my graphic design days.
