reglazing an already fired pot (was: glaze quest)

For Jonathan, who was asking about re-glazing an already fired pot. If you
have access to spray equipment, it's no big deal. You'll need a hair dryer
too. Put the pot on a turntable and adjust the gun to give a fine mist
spray, with just enough air to carry the drops without blasting them away as
overspray. Spin the pot and add just a thin misty coat of glaze. Now stop
spraying, and dry the pot with the hair dryer. Takes maybe half a minute.

Spin the pot again and add another thin misty coat, then dry it again. And
so on, until you've built up the desired thickness. If you get too confident
and let the coat become wet, you'll get a sag or a dribble. Don't cry. Just
wipe it all off and start again, and be more careful next time.

The finished coat can be as thin or as thick as you desire. Works every
time, but notice that the new dry coat will be powdery and fragile, and will
show fingermarks. Pick up the pot by sliding a spatula beneath the base, or
by spreading fingers from within down inside the pot, and load it into the
kiln with care.

Re-glazing isn't just for adding extra thickness to a glaze-starved pot. It
helps sometimes for adding a touch of a contrasting glaze on rim or handles,
to try and rework an otherwise uninteresting bland ho-hum pot. Worth a try.
