I've been painting a new doll, and after firing the first layer of body blushing china paint it completely rubbed off! This hasn't happened before, I'm baffled. It fired to the correct temperature. Are there any artists out there that know what I might be doing wrong? Too thin of a wash? Not enough flux in the china paint? Any insight would be greatly appreciated.
Never happened to me before; some paint always rubs off after the firing but there's still a hue after cleaning the doll. Have you used another brand of China paint? I always sand and clean the doll parts with alcohol before painting.

Yes, same with me. I sand and then clean with alcohol. It's the same brand china paint, so I have no idea, I was baffled. I redid the painting with a different color and will take them out of the kiln today, so we shall see. Hopefully just a random fluke!
EarthShine Doll, this happened to me when I underfired the pieces. I have an analog, manual kiln and I just turned it off 5 minutes too soon. Check your thermocouple, make sure it's not cracked because that can cause the temperature to read incorrectly. Recently, my thermocouple cracked and I overfired a load of porcelain

Thank you tinyshirt! My kiln HAS been underfiring! I realized that just recently with using a clear glaze. (it just turned white because it wasn't fired to maturity.) I will definitely check the thermocouple, thanks for the tip. I have a manual kiln also, and it has been really finicky. I have my eye on a fancy new kiln, I've been saving my pennys...
EarthShine Doll, you probably know this, but using cones can help a lot to give you information about what is happening inside the kiln. Also, once the elements (coils) begin to wear out your kiln will not get as hot as it used to. I too want to have a new kiln, I don't mind that it is analog or manual, I just wish it was a little bigger! Good luck with your pursuit of a new kiln!!!
