These bottle shapes have had a terra sigillata cote and have been fired to 1020.The thin one has had two different colors
Group of bottle shapes before sagar fire.
Here the darker terra is bleeding though.

of terra on and the darker one can be seen to bleed through here and there. I have used a low temp glaze to mask off the parts not to be affected by the smoke. So we shall see how they come out after the smoke fire.
This is a stoneware paperclay body that i used a slab roller and a texture stamp to make. It has been glazed to cone 6 with the following recipe ,—- Porcelain body clay, dry (low temp porcelain 1250c ) 20% / Silica -20% / Wollastonite – 20% / cal bor. frit 5 % / Borax – 15 %/ added 2% red iron ox. and 1% copper carb. The glaze sits well on the body with no cracks but i would like less shine, but not a bad glaze. This was cone six with a 20 min soak. Next time i will add a bit of fine rutil to give it a bit of life.

Here i made this box with a flip top , the hinge has a piece of plastic coated wire in it that i put in after glazing.

This is a low temp. red that has had some iron chromate and frited iron solution sprayed onto the glaze before baking to 1050 c. This is normally a deeper red but now there are flashings of orange and yellows. Different but..

. A slab built box. Here i first put a copper carb. wash ( in the deeper parts of the surface ) and terra sigillata on before bisc. After bisc. i put on a low fire red glaze that i wiped off just so that the terra gets some color and i get a hint of red to give the pot some life. The lower part has a darker terra on and just before glaze bake i sprayed a solution of iron chromate and a frited iron on to the work to get fine spotting on the surface and to accentuate the base line and handles.

Here are some pics of lamp shades that are made from porcelain with a wash out technique before bisc fire. The blue is a diluted solution of cobalt sulphate . They have a cone 6 satin glaze on them.
This is the warm glow they give off just with a low wattage energy saving lamp.
