Franc Holliger adds that she recalls reading somewhere that
sodium, rather than potash, is better for getting a crackle,
and so she suggests using Nepheline syenite instead of the
potash feldspar.

Une way to get a crackle is to have your body under-

Fired, in which case you will probably have trouble with it
not being water-proof. Carlton Ball has a simple solution -

he suggests soaking the pot overnight in skimmed milk, then
allowing it to stand unwashed for about a week, by which

time the milk, having soaked into the pores of the clay,
soured and dried, will leave them filled with casein glue.

He says that the new acrylic paints can also be used to water-
proof a crackle glazed piece. You dilute the colourless e-
crylic with water, pour it into the pot, allow it to soak
through into the body, then, when it has been poured out, wipe
the pot clean and dry and it should be waterproof.

(Incidentally, the soaking in the tea worked beautifully on

my pot to bring out the crackle.)
