Alternative Firing Question- Tebeten Style Conversion

Recommended Posts

Tebeten style black pots;; thats the video on youtube i ran across that sparked some interest... They use a low fire clay fired with wood then covered with ash and sawdust which creates the carbon black color. Then they use a sealant type glaze on the inside of the pots, im not doing their method of glazing... dont trust it...

 

Here is my idea - using a cone 6 clay,  Bisque the pot to 04 - wood fire pot and put in reduction for the carbon black color- then glaze the pot clear and fire to cone 6 ... 

 

Which led to my question- Would this be food safe pottery considering the glaze is food safe?

 

Thanks for any  help... Jim

Hi, I love the look of carbon black pottery.  But I fear if you fire again to cone 6 with a clear glaze, the carbon will burn out - even if covered with clear glaze.  wish I had another idea for you.  rakuku

If the glaze fits and does everything it's supposed to chemically and structurally, it should be food safe.

 

If you retire pit fired pieces like this in an electric kiln though, most if not all of the carbon will burn off, if it's on the surface of the pot. The oxidation/ neutral atomsophere of the electric kiln will alter your fired results as well. I don't say this to discourage you. The results might be interesting. But I think, not what you're after.

If you like that particular black finish with a glaze, burnish in black iron oxide on the surface, then glaze and see what happens. I heard in the 1960s and 70s black Mexican

pottery for tourist was black shoe polish!!!
