Re: Favorite glazes

My biggest joy in glazing this year came with the discovery that you can
paint a coat or two of Spectra's clear crackle glaze over seemingly any
other colored lowfire glaze....it gives you a crackle glaze for any
color that way. If you've never used a crackle glaze, what happens is
that the glaze shrinks a little more than the clay body and creates a
fine little network of cracks in the glaze. You can barely see them, and
the glaze stays put just fine, despite the crazing or crackling. You
then dip a brush in india Ink and cover the crackle glaze (fired on)
area with ink, and then rinse it off. It stains the cracks black!!
Looks way cool! The only thing you have to be sure to do is to cover
the whole pot very well, at least what shows at all, with crackle
glaze...no bare spots of clay showing through. IF you don't get
everything covered, the ink stains the clay gray and looks NOT like
Maria Martinez black pottery, rather like icky ink stained clay. I
always look over the pieces that are crackled VERY well before they go
in the kiln. Kids LOVE this effect, and they make their work look
beautiful. One word of caution, though...don't put crackle glaze inside
of a mug, or a bowl, or glaze a plate with it, or put it INSIDE of a
vase....bacteria will get in the cracks if you try to eat or drink from
it, and the cracks actually would allow water to slowly seep into the
clay if it were a used inside of a vase. We used it on a lot of our 3rd
grade clay animals at www.sjs.org, click on fine arts, click on lower
school art gallery.
