Loran, Yikes I omitted that the glaze I submitted is a cone 10 oxidation
glaze. Sigh.... at least the percentages added up right .
mel jacobson on tue 23 may 00
my favorite glaze of all time for the electric kiln is a combination
of gertsley borate and volcanic ash.
i made a 60 ash, 40 volcanic...added about 3 percent zircopax..any
colorant....and, instant glaze. like cone 5-6. high school kids loved it.
i did a story on that for claytimes several years ago.
if anyone wants the text to read, just send me a private email.
volcanic alone is a decent cone 11 glaze.
add color...zoom \ glaze

Lori,
Thanks for the info!
You are in a grand area - we live in New Mex. but are from the east coast
and we vacationed in your area - Litchfield Beach - we loved it.

I have used the 60% Volcanic Ash -40% G. Borate glaze presented by Mel
Jacobson here and in Clay Times. I have been adding 10% flint but would
like to tone down the results to a satin finish!
does anyone have any thoughts on this?
TY-

What temp?
I'm testing volcanic ash for a satin in cone6 and soon cone9 reduction. I'll let
you know if I come up with anything. But are you keeping it at 100% by taking out
something, tried removing 10 G.borate when you add the flint?

I am assuming you are firing to ^6. To make the 60/40 VA/GB glaze less
glossy try adding some EPK, 10%-15% or so. Also, you might want to
change the proportions a bit.... Try 65/35 VA/GB. Of course, test,
test, test!

Patrick,
Try line blending in some clay to achieve the satin you desire. =
Application may be enhanced as well, though I've noticed this type of =
glaze goes on fairly well without any. Another thing I like about these =
glazes (I use Pumice) is the amount of wet glaze you get from the dry =
ingredients. That pumice really sucks up the water! Also try Alumina =
hydrate - I've had it really zing up some iron gloss glazes, especially =
with rutile.
Best of luck,

The first thing I would try is Titanium dioxide. Adding from 5 to 15%
depending on how much shine and transparency you want to get rid of.

Another comment about the VA/GB mix. As you might know already, watch
out for your colorants. Some act as fluxes and may increase the
glossiness while others, such as rutile and titanium tend to act as
matting agents.
Thanks for your comments about our area, we are lucky to be here (except
during the humidityfests we have so often, at all times of the year).
When I lived in Charleston, SC, I used to throw pots and leave them
uncovered overnight. Maybe, JUST MAYBE, I might've been able to trim
them the next day. So.... we moved to San Diego, I throw my first
California pots and leave them out overnight. The next morning my pots
were bone dry. Well duh! I had always wondered why people used damp
boxes. After that I knew why. I realized I had always LIVED in a damp
box, no need to build one!

Hi all:
I have been working on a standard ash glaze with interesting results.
(any) ash 40
Custer Feldspar 40
Ball Clay (I use OM4) 20
I first fired to ^9 oxidation and was greeted with a lovely satin oatmeal
with slight rilvulet. I will test in reduction and let you know the
results;

I found the same thing here in New Mex.
When I lived in Pa. throw one day and if all the moons were in the right
places, you might be able to trim the following day. If it was regular
humidity it might take two days and when it got real bad - out came the
BIG fan.
Here it is completely different - we do an annual "BOWL-A-THON" where
about 20 potters gather at the local U (NMSU) and throw about 600 lbs.
(Commerical - its donated by Laguna). This is our "Empty Bowls" project
to supprot the local feed the poor programs. The throwers start about
8:30 and at about 10:00 AM the trimmers are at their tasks. These are
ready to load for bisque firing by end of day.
Keep that mud flying!!!
