Mary-Helen,
I just tested Bell's Lichen Glaze from Lana Wilson's CM J/J/A '95 article.
It's a ^5-6ox. I fired to ^5 & it came out fine for my sculpture but I
think it would be too rough for functional pots.
Here's the recipe in case you want to try it:
Bell's Lichen ^5-6 ox
Magnesium Carbonate 31
Talc 8
Zinc Oxide 6
Frit P-25 (I used 3269) 6
Soda Feldspar 30
Kaolin 19
note: this recipe is slightly different than the one she gives in her book.
hope this is what you're looking for,

Hello all -- hope you can help. I used Richard Burkett's Texture Crawl
glaze (posted in Glazebase) to get a beaded, or at least textured surface
on the exterior of some pots. But none of my tests are giving any sort of
beading or texture, beyond a rough matt.
The recipe is intended for cone 6 ox:
Nepheline syenite 70
Magnesium carb 25
Ball clay 5
I sprayed, sponged and brushed the glaze on various bisqued pieces. The
application seemed pretty thick to me (a bit less than a mm). Some tests
were applied over other glazes and others were just applied to the clay
surface. I fired the pieces in an electric kiln to 2165 degrees F (cone 5).
Don Davis has a similar recipe in his book, which he calls Separating
Glaze. His application shows a fine mist where it's thin and a nice,
gnarley pattern where thick. I tried that, too, to no avail. Has anyone
used this or similar glazes?
Thanks, in advance, for any ideas or help.
Kind regards from Georgia,
Mary-Helen

The first thing, apply very thick. You can add CMC and apply with a brush
5-10 times!
If it will not help fire in ^6 if it will not work buy lana Wilson's book
she has a full chapter on this issue
See in my site in stoneware.

Try increasing the amount of Magnesium carbonate in 5% increments until
you see the glaze separate. And just an observation, It is difficult to
get this glaze to separate when applied over or under another glaze.
The other glaze usually has ample flux to melt the Textured glaze
smooth.

Mary Helen,
Textured glazes really need to be applied thick, and that means very
thick. If are left with just a rough glaze then you did not apply it thick
enough.The glaze has to have cracks in it before firing. Add some binder to
your glaze and reglaze your pot, possibly it might give you the surface you
were looking for.
I have had good results with the following:
MarK Bell Lichen glaze cone 6 -8 (CM February 1990)
Soda Spar 30.
Magnesium carbonate 31.
Frit 25 6
Talc 8
Zinc oxide 6
Kaolin 19

Mia,
I am puzzled by your statement: "The glaze has to have cracks in it before
firing."
Could you explain?
