Earthenware Glaze Tests (low fire)

I have been experimenting with different low fire glazes. These glazes are for earthenware with a low firing temperature to cone 04. (1060 degrees Centigrade, or 1940 Fahrenheight)

This is partly because I have been working with found objects from the clay recycling room and these  shapes are usually made from earthenware, the clay utilised by the Introduction to Ceramics students in the studio.

I am interested in both glazes that run or form a drip, and surface texture.

My first experiments were with thickly applied majolica and willing white. The test pieces were dipped 6 times and the glaze was about 1/2 centimetre thick. Whilst interesting, the results weren't quite what I was looking for.

Next, I experimented with double dipping of glazes, combining gloss finishes (such as power black) with textured finishes (Vardis blue).

Turquoise and Power black

It was also interesting to see how different glazes responded to being dipped first or second. Depending on this the resulting texture changed.

I then became interested in experimenting with layering different glazes combined with wrapping either copper or steel wire.
