Greetings,
Do any of you glaze collectors know of a glaze named Woo Blue? It
looks somewhat like Floating Blue, but there is more brown. I would love to
have it if you don't mind sharing. TIA Toni

Wow! Had to dig deep for this one. This is the recipe for Woo Blue I
used in Ohio back in 1974. It is for reduction, to be fired to cone 10.
It went that iron/rutile blue where the application was of medium
thickness, and where thinner broke brown. It worked well as a base
glaze, which was then wax resisted and the pot was then dipped into a
glossy white, which overlay it and broke up a bit.

My understanding is that the glaze was developed by either Robert or
Marie Woo, from around the Detroit area. Anyone else know the history?

Woo Blue c10 Reduction

Kingman spar (Custer now) 42.0
Silica 27.0
Ball Clay 13.0
Whiting 18.0

Red Iron Oxide 4.0
Rutile 4.0
Bentonite 2.0

This was used on bisqueware. If I were to single fire it, I'd up the
bentonite content to around 4.5%.

Woo Blue Brown Reduction Fire Cone 10

Potash Feldspar 41.60
Flint 26.70
OM-4 Ball Clay 12.90
Whiting 17.80
Bentonite 1.00

add
Red Iron Oxide 4%
Rutile 4%

Color: (rutile)blue to brown
Surface: shiny
Comments: Apply medium to slightly thicker. This glaze goes brown if
very thin, orangey-brown if thin, blue breaking to brown if medium, gets
bright purplish overtones and very "fat" looking if thick. Runs badly if
very thick.

Try it.!

Toni--Here's a formula I have for Woo's Blue. I found it very
tempermental, but you may find otherwise. I fired it in reduction to ^9-10.


Whiting 18
Custer Spar 42
OM #4 13
Silica 27
Red Iron Oxide 4
Butile 4
Bentonite 1

Hi there, I'm a pottery/art student at Palomar College and Woo's Blue is a
standard glaze in the student glaze room. It fires a real nice deep blue in
a good reduction at cone 10 in a gas kiln. It is one of my favorite glazes
and I hope you enjoy this batch as much as I do. I also like to put Rhode's
White over it for a nice blue and white mottled effect. I've written down in
the weight that we make it up in the glaze room, so I hope that's all right.

Woo's Blue:

Custer Feldspar 10lbs 8oz
Whiting 4lbs 8oz
Ball Clay 3lbs 8oz
Silica 6lbs 12oz
Red Iron Oxide 1lb -
Rutile 1lb -
Bentonite - 4oz
Mix with approximately 10 quarts of water. You want one or two drips to
come off your finger when you dip it in the glaze to test it. It should coat
you finger nicely with one dip and not be runny. Good Luck.

Hello clayarters,

I just had an interesting thing happen when I refired a couple of
bowls glazed with woo blue, fired to cone 10/11 in a reduction
atmosphere. These two bowls had a couple of blisters on them so I
dabbed on a little glaze on the blisters, and then I also sprayed
some more woo blue on the inside of the bowls. I usually do not
respray when this happens, but did this time.

One bowl came out with beautiful black and gold crystals, really
gorgeous. The other bowl looked like the glaze had been sprayed
through a screen, and also is a real winner.

The recipe is, (and someone posted this on clayart a couple of years
ago, and I am sorry, but I don't know who to credit it to)

Cone 10 R

Woo Blue

G-200 42
Silica 27
Whiting 18
OM4 13 plus red iron oxide 4, rutile 4, bentonite 1

Dipped or sprayed on. When sprayed on, it goes a beautiful
rust/orange where it is thiner, and a warm blue where thicker.

Seems to me that Joyce once said that she got these beautiful
crystals with a rutile blue once.

Thought I would pass on this info. in case others want to try it. Of
course it probably means refiring, but sometimes the inside of bowls
glazed with a rutile blue will blister.

Meticulously loose Liz

Woo Blue is one of my favorites when I fired in reduction. I now fire at
cone 8-cone 10 in Oxy. I recently tried a recipe for a floating blue that
looks just like Woo. I am thrilled. Jeri

I use this recipie and consistantly get a soft green. a little blue tint,
but green i like it anyway. It's great over a temmeku. My own dishes are
that combination in fact.

I believe Woo Blue can be attributted to Mary Woo. Ceramics monthly
