I have just made some paper clay dresses covered in roses, bows and lace dipped in slip.After the bisque, which is happening now, I shall colour the roses and bows a delicate pink and would then like to spray all over with a clear satin glaze, firing again to 1240 degrees or Cones 7 to 8. I can find plenty of semi clear satin glaze recipes in that firing range but feel I need clear in order for the pink to show through. Some dresses I want to paint black with green and white lilly flowers highlighted so clear glaze would be best. The only reason I am glazing at all is to give strength to the thin flower petals and lace. As I want the dresses to look old world, I think a shiny glaze could be too glitzy and take away from the antique look Im trying to achieve/ Any suggestions?Im using a 10 cubic ft electric kiln........Fingers crossed, Judi Smith, Taupo, New Zealand.

Dear Judi Smith,=20
The term "Clear Satin" has me worried. Were you able give us a few =
examples of the recipes which are Semi Clear Satin some one might be =
able to help you with a modification.
But to explain my misgivings. There is a need to describe a satin =
surface. My interpretation is that the surface is slightly reflective =
but obscures or eliminates the definition of any reflections, especially =
bright highlights which can mask visual details in modelling or =
decoration.
I know of two ways to do this. One is to grit blast the surface with a =
very fine abrasive. The other is to use a glaze which will precipitate =
microscopic but reflective crystals. Both have disadvantages. For the =
crystal method, the problem is to get selectivity so that crystals grow =
at the surface but not within the mass of the glaze. Other people may be =
able to offer more information which may be of help.

I read your posting on clayart a few days ago but did not see any
subsequent replies........what an interesting project..
My basic glaze (4frit 4kaolin 2feldspar 2silica 1calcite 1talc by
volumes) works really well on most clays at cone 6/7 and it not too
shiny
sprayed on should be fine
you could use the variations which include extra clay to subdue the gloss.
refer http://www.gartside.info/briansbasicglaze
You would need to do some tests
write to me off list if you want further details.
