Hi, our mid fire bisque firing accidentally fired to cone 6. Needless to say the owner feels terrible. So we all want to know if there are any tips for glazing at this point or if it's futile. Any suggestions would be greatly appreciated! There's alot of sad people down there.

No need to panic ... This has happened often.

The glazes will have a hard time sticking to the surfaces. One idea is to warm the pots in a low ... 200 degree F oven ... then glaze them. Glaze will adhere and everyone is happy.
You can also add gums or CMC ... But warming them in an oven is quick and easy

Hair spray helps I've heard ... gives some temporary sticking ability for glazing.

Chris, somebody down here was asking if a microwave would work? No oven on site.

No oven, use a kiln! or even a heat gun. All you are looking for is a bit of heat to make the glaze liquid evaporate faster.

I've used the microwave to heat pots I want to refire. It helps the glaze to stick to already glazed surface. Maybe it would work for you on unglazed pots as well.

If your glaze has high clay content , it will stick.
To glaze over fired bisque, as everyone has mentioned, heat the pot. Heat guns work well.
If the glaze is thin, heat again and dip. Keep adding until you get the enough on the pot.
