Bright Green Cone 10 Glaze
 
Since I am nervious about using Vanadium to make a bright green glaze, does anyone have a food safe bright patina-copper green they can share?

I should note that I do have an 80's fashion, oh-my-god-green that is so unnatural I can't stand it. But my students love it, so I will share it to get this topic started. Plus the formula appeals to my sense of organization as the ratios are 1,2,3,4:


BLINDINGLY BRIGHT GREEN
Cone 10, Redux
Gloss, Opaque, Viscous, Bright Spring Green
Best on iron clay such as Rods Bod or Death Valley which creates dark flecks and variations in the green. On white clay the glaze is solid, unchanging, blindingly bright green.

Patina Green - used by Tom Coleman.  This glaze appeared in Ceramics Monthly.

Cone 10 redux

 

Custer Feldspar     52

EPK                     10

Barium Carbonate  38

add:

  Copper Carb        4

Tom Coleman recommended this recipe as a good base glaze to play with color variations.  A good, stable, flexible glaze.

Here is a fun one if you are in the mood for something different.  Rare Earths are available by special order at Capitol Ceramics.  Rare Earth oxides (Praseodymium Ox, Neodymium Ox and  Erbium Ox) are just as safe as our common oxides such as cobalt ox.  Normal precautions.

 

 

Rare Earth Celadon-Tyoe Galzes

 

Wollastonite          26

Zircopax                1

Custer Feldspar      27.5

Grolleg Kaolin         20

Veegum T               1.5

Silica (325-mesh)    24

add for preservatives:

  Copper Carb         .02

  CMC Gum             .4

 

Unreal Green

   Praseodymium Oxide  .65

 

Apparently Lavendar (see NOTE)

   Neodymium Ox  4.5

 

Unreal Blue (see Note)

   Neodymium Oxide  1.10

 

NOTE:  Neodymium has a wonderfull (and in sales sometimes bothersome) trait of changing color in different lights.  Blue in florecent light and purple in sunlight, etc.  It is reportedly green in some light, but I have not seen that myself.

The Jewel Base Glaze comes from Ceramics Monthly.  Very high gloss, transparent glaze.

 

Whiting             24

Custer Feldspar  28

EPK                  20

Flint                 28

add Zinc Ox        3

 

For emerald green

add:

   Chrome Ox       0.4

   Cobalt Carb      0.5

 

For saphire blue

add:

   Chrome Ox       0.3

   Cobalt Carb      1.0

 

Will crawl if too thick.  Excellent as a second layer.  Saphire used over Blindingly Bright Green (See glaze at top of this topic) it makes black gloss glaze with nice depth.

Linda Lou's Jade Green:

Dark green semi-matt.  Cone 9-10 redux or ox.  Will work in electric kilns.  Very stable, does not run.  Excellent for a second dip on top of a runny glaze.  As the first glaze runs, the stable jade green splits and cracks to show the glaze below.

Neph. Syn.     700

Whiting           50

Colmanite        20

Ball Clay          80

Silica              60

Bentonite        30

Chomium Ox      5

Tin                 20

Rutile              20
