Ruined Pit Fired Pieces

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

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.

But would any clay vitrify at pit fire temps ( low )?

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.
