Re: [art_education] Re: Acrylics/ceramics glaze question
- Just a thought.... I don't leave projects that should have my supervision for subs because I've found (unfortunately through trial and error) that things get screwed up way too easily. Maybe you have special 1 day assignments for sub-days, and assign a student from each class who knows exactly where these are, in case of necessity. Or get the students started on sketches for the next project, or journaling/writing the process down for the project exhibition. Those are my thoughts, at any rate. I hope that you project has turned out alright in the end. I'm jealous of your classroom, your kiln & that you know how to use it.... that was never my specialty - I's a illustrator/design sort.best,jen spenceny, ny----- Original Message -----From: jdecker4artSent: Monday, March 05, 2007 5:47 PMSubject: [art_education] Re: Acrylics/ceramics glaze question
Hi Sarah and all,
I answered Sarah off list already.... but thought I would tell all
that the acrylic paint would burn off in the kiln. It may leave a
white residue that you can scrub off. When dry - glaze the cup and
fire again. Be sure to fire in well ventilated room and have plenty of
kiln wash on your shelves. I would not mix properly glazed pieces in
with the acrylic painted ones.
I found this online:
"What will happen is that the paint will burn off
leaving a white powdery residue on the clay . I usually scrub the
residue with water and brush. After it's dry go head and glaze, With a
dark color. Hopfully, it will cover it , but then again it could
It is possible the glaze will not properly stick to the clay body and
may "crawl" - leaving bare areas.
Definitely do not try to glaze over the paint as the paint will act as
a resist and the glze will not stick when fired.
I suggested to Sarah that she try firing one.
