What people mean by a flashing slip is that they are applying a kaolin or
clay to a pot and then firing the pot in an atmosphere that has vapor in it.
salt kiln
soda kiln
wood fired kiln
Avery kaolin used to be the great clay to use for a flashing slip, but alas
it is not mined anymore.
you mix it 75 % kaolin with 25 Neph sye and mix it like milk and dip it on
your bisqued porcelain pots, fire in a salt kiln, ooo la la
there are people who dip there leather hard pots in tile 6 kaolin that is
mixed thick with no additive, Linda christenson does this and wood fires
and I think sprays soda into her woodfired kiln.
Michael Simon also does this and fires salt, or he did when I took a class
from him.
EPK, grolleg, tile 6, helmar, all flash or pick up different colors from the
different types of firing that you put the slip into.
even a thin slip made out of red art is fun to use. Or a slip made out of a
fireclay looks great
it is good to test individual clays in the kilns and then you can mix and
match and add together.
I use a combination of kaolins to get a nice color range,
the thing to remember is that when you use a slip, they do not have a lot of
silica to them, so they tend to be refractory when you fire, so I do salt ,
and I find that I need to use more salt so the slip will pick some up.
good luck

Hi; I've noticed that the kaolins which have a fair amount of Titania in
them make good 'flashers' so if you are looking around for one, check out
the % Ti. Hank
