I have been testing something and it isn't 100% a sure thing, but its close.
A "Sharpie" permanent marker has worked as a RESIST for me. I found this out
by accident. I made and glazed bowls for our Empty Bowls charity event and a
couple of them had pinholing so I didn't include them in the sale. After the
sale I thought I would re-glaze and re-fire them, so I did. I only waxed the foot
and not the bottom of the bowl as I wanted to cover up the "Empty Bowls"
words I had written on the bottom with a Sharpie Permanent Marker. Imagine my
surprise when I pulled the re-fired pieces out of the kiln and there on the bottom
were the unglazed words, "Empty Bowls"! Some how during the firing the
permanent marker actually repelled the glaze and it crawled off the marker. It
looked as if I wrote "Empty Bowls" with a brush and wax resist. It was very clean
and precise. I have since tried the Sharpie Marker on bisqued pieces and
dipping in a glaze and it will repel the glaze on certain glazes and if the glaze is
thin. I fire to Cone 6. I tried other permanent markers like the Bic Soft
Feel and the glaze covers the marker and it doesn't work as a resist.
If anyone wants to try this out and has good results with other temp. firings
I would be interested in hearing about your results!

That's interesting because I've used the black sharpie to transfer designs
and to 'sketch' on bisque (low fire or slipware) and it burns off completely
at cone 06.
More experimentation is needed it seems.
