Back in February this year there was recipe for a Nutmeg Glaze in=20
Ceramics Monthly configured to fire at Cone 6. The picture of the=20
glazed pot intrigued me. I was wanting a nice light brown to add to my=20=

palette of colors, but I fire up to cone 10. I played around with the=20=

glaze and these are some of the results I have come up with so far.

1st Variation
Reduction
1280=BAC
Dolomite ---------------- 23.30
Feldspar ---------------- 36.90
Ball clay ---------------- 23.30
Silica ------------------- 16.50

Add Red Iron Oxide ------ 1.07
Terra-cotta --------- 3.24
Zirco ---------------- 4.85
Bentonite ----------- 1.94
Came out a thin nearly transparent green. Not suitable at all.

2nd Variation
Reduction
1280=BAC
Dolomite --------------- 23.30
Feldspar --------------- 36.90
Ball Clay --------------- 23.30
Silica ------------------ 16.50

Add Red Iron Oxide -------- 4.0
Rutile ----------------- 1.0
Zirco ----------------- 4.85
Bentonite ------------ 1.94

1 part SATIN MATTE (below) 3 parts NUTMEG produces a deep brown with=20
slightly mottled orange highlights.
1 part SATIN MATTE, 2 parts NUTMEG produces a lighter brown with more=20
pronounced orange mottling.
Both are gloss. Satin Matte applied under is an icky green; applied=20
over (thickly) is a nice white.
3rd Variation
Reduction
1280=BAC

Dolomite ---------------- 23.30
Feldspar ---------------- 36.90
Ball Clay ---------------- 20.30
Kaolin ------------------ 13.00
Silica ------------------- 6.50

Add Red Iron ----------------- 3.0
Rutile -------------------- 1.0
Zirco -------------------- 4.85
Bentonite -------------- 1.94
Using the same PART(S) mix as the 2nd variation produces OLIVE GREEN. A=20=

little less glossy. Satin Matte over the glaze hardy showed at all.=20
(maybe it was too thin)
Variation 3 used alone (first try doing this) produces a really=20
wonderful light toasty orange-brown. Satin Matte over the glaze showed=20=

much better than over mixtures.
Red Iron Oxide brush work on 1st, 2nd, and 3rd variation mixtures=20
melded and flowed very well. On the unmixed 3rd variation it is dull,=20=

flat and unsightly.

There are a few more variations I plan on trying. Basically, I want to=20=

make the glaze completely Matte. I don't care for 1st and 3rd=20
variation mixtures. The 3rd variation used alone is very satisfactory.

I used a 50/50 mix of iron bearing slight sandy clay and a very fine=20
white clay.

This glaze has caught my attention because I get cone 7 in the flue
channel of my wood kiln, that runs the length between the two fireboxes.

Seems to be several versions running around. I found one with frit
and another without. Which are we talking about?


Here are some tests of John Anthony:

He fires cones like I do. His cone six is probably the factory's cone =
7.
