Can I paint on glaze on top of already fired store bought tiles?
How do I know which glaze to use or how hot to fire them?
I have an electric paragon kiln
Also need wholesale resourses for glazes and clay

The answer to your question about refiring manufactured tiles that
you've painted on top of is "Maybe" or "Sometimes". Like the answer
to all questions about ceramics, it depends.
Many people decorate commercial tiles using commercial low-fire glazes
and refiring to cone 04 or 05. The glazes you apply will work pretty
much all the time, but in some cases, the glaze that was on the tile
to start with will be affected by the refiring. This is particularly
true of tiles made in the new roller-hearth fast-fire kilns. Many of
the large tile manufacturers have gone to this technology in the last
few years, and the quality of the product has dropped dramatically.
So the bottom line is, you need to test-fire each brand, and indeed
each color, of commercial tile. Sometimes the color will change,
sometimes the surface. I have heard that most of the fast-fired matt
glazes will not stay matt when refired.
Now, you may not care about this, but if you're trying to make deco
tiles to intersperse with field tiles, it can be maddening.
Another option to investigate is china paint. This is fired to such a
low temperature that it leaves the commercial glaze unaffected. I've
fired scores of different brands of tile with china paint, and only
once have I seen the original glaze change. This was on a Mexican
tile where the glaze was so soft it was remelting at cone 016. A real
quality product! I wrote an article about china paint for Ceramics
Monthly that was published in the February '95 issue (I think). If
you're coming to ceramics from painting, you'll love china paint.
It's more like water color than any other ceramic thing you can do.

I've done it with elementart students. Used low-fire Amaco glazes. Fired
*06.

I bought bisqued tiles from Dal Tile for a project where I glazed these tiles
for a shower installation. I fired them to the cone that the Tile Company
told me to. They seemed to be knowledgable about people refiring their
tiles.

Just for curiosity what did they tell you to fire it to? I buy from
Dal-Tile here in Sarasota and they could't answer. I'ver been firing 06.

Hi,
You must find out the ^ the tiles where fired to. Then you can match up
the glaze. I know a potter who tried reglazing tiles and the glazes reacted
badly, he had crazing, and bubbles (due to escaping gases). Good Luck

Did you get the information you needed? I am in the process of
sifting through a weeks messages. I have a glaze rescipe that can be used
on terracotta manufactured tiles. Low fire. Paint with underglaze colors
and mason stain.
E-mail me if you want me to dig it up for you. Pamela
