layering glazes,,,,,,,anything new

I continue to be very interested in layering glazes and was wondering if
anyone out there was doing anything new in Cone 6.

Recently been doing a few experiments of my own and have found a great
combination using a variation of Jane Shatz Blue Matt and Nutmeg. I have
found that you can layer one on top of the other either way and get some
nice effects.

If you look on my web site and scroll down to a green bowl below a face jug
you will see what you get when you put green matt over nutmeg. I poured one
layer of each about the thickness of milk.

Here is the green matt receipt. Nutmeg is in the archives.(Richard Bursch's
recipe).

Recipe Name: GREEN MATT

Cone: 6 Color: blue
Firing: Oxidation Surface: Matte

Amount Ingredient
7.2 Dolomite
11.3 Gerstley Borate--1999
13.9 Talc
39.1 Nepheline Syenite
9.5 Kaolin--EPK
19 Silica

100 Total

Additives
4 Copper Carbonate
6 Rutile

Would appreciate anyone sharing any other great combinations in Cone 6.

Randy-
Thanks for sharing your results. I really like the vase that is third
from the bottom. Would you be willing to share how you achieved such a
lively layering effect?

When I end up with bisque items that don't "cut it" I experiment with
glaze layering on them. I have annotated & posted some of the results
on my Flickr set at
http://www.flickr.com/photos/ivyg/sets/72057594093102627/
The latest one is a layering of Waterfall Brown and Cindy Strnad's
Opal Blue (recipe is in the archives) that I must humbly say is a real
knockout.

That small vase was a layering of nutmeg and the green matt plus I brushed
on some waterfall brown. What I have found though in getting some great
effects of layering is to put a hold on your kiln for at least an hour
beginning at 1700 degrees F. When I turn all my switches on Med at 1700
degrees I get a very slow drop to 1600 degrees F. That's where I am getting
some nice depth with the electric. I have been holding at about 1900 F, but
did not see much there.

You have to be carefull with some of the cone 6 glazes when you do the hold.
My jade green glaze ran where I had applied it too thick. Med thickness on
a couple of bowls turned out great though. The jade green is just
Chappell's Floating Blue base with 4% copper and 6% rutile. It is one of
the best glazes I have come up with lately. The jade green is the first
bowl on the web site.

I am a bit slow onto this thread but here goes...
Using a simple base glaze many different stains or oxides are added.
I have had consistent and developing effects by using the glaze with
iron oxide first and then (substituting other colours for the iron
oxide) layered or poured or dribbled or brushed over each other......

and the then browse here for glaze itself

one glaze....a hundred affects
Warning..this method is not suitable for anyone addicted to complexity :-)
