This recipe can create a gorgeous golden shine where the correct thickness, and a deep red/saffron where thin.
Best when fired under heavy reduction.
Feel free to play with the soda ash concentration. More soda may result in more carbon black, less soda may result in a dryer, saffron-red glaze instead.
Feel free to try out different kaolins. Grolleg, for example, may flash a brighter orange, and a dirtier kaolin may result in better metallic colors.
I have not tested this in a wood firing, but I would recommend it only for an inside liner, as its not a hi-alumina type. Alternatively, you could try leaving out all the soda ash and seeing what that would do.
