Attended a ceramics class and of course, as we were pit firing it rained and doused the fire. The results were not pretty! I'm now back home and only can electric fire. Can I add low fire glaze to the bowls and re-fire them ?
Yes
yes, or try raku or high fire on the same pieces.

by the way - i only use cone 10 clays for raku, pit, high fire. so i can swap a pot thru all of the processes with no problem.

Ahhhh, but will it be vitreous at pit fire temps ? Prolly not. Best, Wayne Seidl

For instance, even if you buy a clay designed for low fire, it doesn't vitrify or it's still quite porous compared to higher temp firings. Of course it depends on the supplier's blends. I was guessing you'd have to get up to Cone One* to get any great degree of non-porousity. I think I saw Cone One called a terra cota temperature on one list. Any that's still porous

*Sorry I don't have my book with all the cone temps.i accidently got some 06 clay (powdered slip) into a batch of cone 10 pug mill clay. discovered AFTER i dumped half a bag in...
anyway, it fired up really well. i was lucky the proportions across the whole batch was small. everything got an extra smooth finish.
so while you might find some o6 clay to use, i still like using only one type of clay in the workshop to avoid these accidents.
