PEACOCK BLUE MATTE

My original #507-15 glaze from my first glaze class, a dependable semi matte glaze that makes a variety of intense turquoise blue colors depending on the percentage of chromium oxide or cobalt carbonate added.

COPPER GREY

A semi-matte glaze that usually fires a solid pewter grey without much difference between clay bodies.

Occasionally flashes reds and pinks.

VICTORIA'S CREAM

I got this recipe from Victoria Morris.
A creamy matte buttermilk that turns much whiter on the second dip. It has a great smooth texture and varies greatly depending on the clay body.
High in Barium, and turns much more yellow in the presence of iron.

This glaze is extremely matte and will stain with a marker - probably not a good choice for dinnerware.

Zircopax plus                        128
.5% yellow iron oxide

*adding
up to 2% yellow iron oxide will make a pretty yellow

750 ml H2O

GLOSSY GLAZE 709-27

This was Sandy's glaze and made several nice colors with the addition of iron and nickel,  and an incredibly reactive vanadium glaze I am calling "Starry Night".


Nickel made a nice grey-brown, especially at Ni-1(.4%) and Ni-2 (.8%):

Starry Night was best around 2-3% vanadium.

 Fe-2, Fe3 and Fe4 all made pretty blue greens.

GLOSSY GLAZE 705-15

D: a nice honey amber color
G: a tobacco brown
K: looked like coca cola, with bits of blue in it.
M: looked like blue smoke
P: a gorgeous deep plum with lots of variation
R:  a dark smokey grey.

HARE'S FUR GLAZE

I hope this one works! I tried the Nuka recipe.

Tested on several clay bodies.

RESULTS:
I tried the "Nuka" recipe.
This didn't turn out at all like the image above, but it is a nice matte white glaze - very clean white with good coverage.
Here it is on Babu, granite, soldate, and black mountain:

*Ok what I realized is that you have to use BOTH glazes together!

GLOSSY GLAZE 905-6

Glaze 905-6

A glossy glaze with a slight crackle.  Has some magnesium in it.

Custer Feldspar                           392

Wollastonite NYAD M200        161

Talc                                            42

Grolleg Kaolin                            59

Old Mine #4                               87

Silica                                         259                  Total 1000

H₂O:  700 ml

Rogers note:
"This one is similar to 1108-30 but with a bit of magnesium.  Probably would be a good testing base, but the W-30 wollastonite might make it a bit hard to screen."

RESULTS:

My glaze didn't have any crazing.

Added praseodymium yellow at 8% 4% 2% and 1%

Very pale sherbet green colors.

At 8% The glaze needed more water - you can see that it crawled.

Lavender stain at 8%,4%, 2%, and 1%

 

Additionally added some neodymium to the  4% Lavender, and tested a tile that was a "mix" of all the percentages.

Seems to be stable and reliable, but also a bit boring glaze without much depth.
I should test it on some other clay bodies.

MATTE GLAZE 605-61

605-61    Matte

NC-4 Feldspar               410

Nepheline Syenite        123

Dolomite                         77

Barium Carbonate          64

Strontium Carbonate      75

EPK                                 139

Silica                                112                           Total  1000

H₂O:  750 ml

From Roger:
"Probably best to avoid a matte like this (Ca, Mg, Sr, and Ba) with nepheline syenite as the alkali metal source."


I decided to try it anyway - I like the barium/strontium - i hope it will brighten the colors.

RESULTS:

Pink at 8,4,2,1%

At 8% the glaze is textured and ultra-matte with a rough texture.

And a bit of Neodymium to 4% Pink made it a bluish-pink.

Here is 4% on black mountain and granite

*The Praeseodymium seems to need a bit more water - it was very thick at 8%

It seems that the higher percentage stains came out more eggshell then matte.

At 8%, 4%, 4% with a unmeasured (tiny bit) of peacock added, 2 and 1%

At 1% the color is not noticeable

RESULTS:

I like the this glaze a lot.  It has a great feel, like marble.  It seems to get a bit shinier with the higher percentages of stain.   I really like the base color, without any stain added.  I will test this base with a few different clay bodies.

Here are some samples with various mason stains, fired at cone 10 reduction.

GLOSSY GLAZE 506-5

506-5       

Very glossy bright white with a slight crackle.

Spodumene Concentrate              85

NC-4 Feldspar                          358

Ferro Frit 3124                           50

Tri-Calcium-Phosphate             103

Talc                                          72

Grolleg Kaolin                           85

Silica                                       247

                                             ____

                                              1000

H₂O:  1000 ml

"This is a base with P₂O₅ and MgO, a base that will make persimmon colors from iron, might be interesting (uses a good bit of water because of the tri-calcium phosphate). "

Added Mason Tangerine at 4%.

Also added ilmenite to one test tile.

RESULTS:

I like this base a lot.  Interesting crackle when stained with India ink. They get larger when the glaze is applied thicker.

Tested on porcelain, black mountain and soldate to see if the iron reacts.
The iron did not seem to affect the color, but the Ilmenite looked interesting.

The tangerine is a bit dull - more a fleshy orange.. I tried another test at 2%.

Pink at 6%, 3% and 1.5%
the color is not present under 3%.

Peacock at 1%, .5%, .25% and .125%

1%, .5% and .25%

.125% and Base color

Yellow at 8%, 4%, and 2% ( the test tile labeled 1% is wrong)

* The test pieces seemed to get a lot of pinholes on the second dip. I smoothed them over on a few sides to see if they show up after firing. They didn't seem to show up at all.
