resist painting on bisque

Clean the bisqueware well and let dry thoroughly.
Draw or trace your design. I used a 2HB pencil, very lightly.  Carbon paper is fine too.

Fill in the drawing with resist: here we used a latex-ammonia emulsion that is sold for watercolor painting resist.
 Next we sponge painted the entire surface with a turquoise underglaze tapping out from very thick in the center and under the big flower to a lighter dapple moving towards the edges.
Looks pretty funky at this stage!
Once the layers of underglaze dried thoroughly, we removed the resist using a thin wooden skewer to prevent scratching.  The stiff coat of underglaze sometimes wants to chip along the edges as the latex is peeled off, so in some spots I chose to use a razor knife to cut a clean line.
This platter is 16" wide which is too big for me to dip it into the clear glaze so I sponged on 3 coats of clear. This is what it looked like with the first coat; after the third it was entirely opaque.

Once this was thoroughly dry I turned the platter over onto a big clean felt and gave the underside several coats of clear glaze.
and once that dried? Ready for the kiln!
