Layering slip and glaze

Here I’ve tested to see what effects can be had when layering slips and glazes onto ash white stoneware.

  1. White slip with turquoise glaze on top produces crazing in straight lines underneath a patchy shiny green.
  2. Reversing the above with the white slip on top creates a dry, textured matte surface which doesn’t flake or peel.
  3. My favourite – yellow/green glaze with blue slip painted on top forms islands of matte dark blue over a shiny surface with a very painterly effect. I like this rough, uneven texture which might look exciting on a large scale.
  4. The same as 3 but with turquoise glaze on top – this looks like a painted landscape with lots of variations of blue and hundreds of tiny bubbles encased in the surface.

I expected the slips to run off the surface when fired but the addition of glaze works to stick the raw and bisque fired clays together.
