Hi all:

Does anyone have a recipe for an Orange peel" glaze ie bumpy, crawley, or
what ever it means to you. Preferably ^6. I checked Ceramicsweb database
and came up with nothing. (I probably did something wrong.)
Thanks!

Emily

If I am not mistaken, orange peel is a salt glaze. I have a very fine
piece done by a friend who studied in Japan years ago. The texture is
like the peel of an orange.

May be wrong, but I have always associated "ORANGE PEEL" texture glaze
surface the product of a particularly nice SALT GLAZE.


however....
I can imagine a low fire...sort of "controlled crawl" glaze that would
resemble that type of texture...and have seen some low fire glazes that
might be considered 'orange peel' textured. Most likely to be found in a
hobby glaze at cone 06 or lower. Check out AMACO, DUNCAN or GARE
suppliers...look in a catalog at their color/texture illustrations....That
might take you close to what you are searching for....?

Happy potting!

You can probably use any fairly glossy (ie not dry) crawl glaze and SPRAY
it on the piece to get a more orange peeled surface. Dipping or brushing
will give more flat platelet type crawling. Spraying, especially if the
glaze is sprayed from a great enough distance to get a somewhat drier
application (a very pebbly surface in the raw glaze) will usually result
in an orange peeled surface on the fired glaze. You could try the
following glaze:

Glaze name: Texture/Crawl glaze
Cone: 6
Color: white
Testing: Tested
Surface texture: crawl
Firing: Ox. or Red.
Glaze type: crawl

Recipe: Percent
Nepheline Syenite 70.00
Magnesium Carbonate 25.00
Ball Clay 5.00
Totals: 100.00 %

Comments:
Works well over slips. When sprayed it develops a finely pebbled surface
even when fairly thin. When brushed it breaks into a more platelet-like
crawl. Can be fired to a higher temperature to get a glossier surface and
more rounded globs of glaze. Good response to colored stains brushed or
sprayed over. Try this over dark slips or engobes for a dramatic effect.
You can make this glaze bead up just by spraying it on thickly or at least
somewhat drier than normal (step back from the piece while spraying so
that the droplets of sprayed glaze dry out a bit before they get to the
piece), so that the surface is very pebbly BEFORE firing. You can control
whether it is a fine pebble or large beads this way - Thicker=glassy
beads, thinner=fine pebble. Brushing or pouring it tends to make it break
into more flat platelets, although firing a bit higher will usually
convert a thickly crawl glazed piece to bead-like droplets. Doing this
with any crawl-type glaze, along with firing the glaze a bit hotter, will
help promote beading.
