New Glaze Tests- Cone 5 Oxidation

Even though it takes a lot of time, I love playing around with the computer and chemicals to come up with new glaze recipes.  I recently mixed up 6 new attempts at various colors and came up with two I like.

The first is based on a very stable base for a matte glaze I already use with two of my colors "Sage" (formally Carribean Sea) and "Ocean".  With the new still unnamed glaze, I added 2% Red Iron Oxide resulting in this wonderful glaze.  The second picture is the new glaze on the top rim of a glossy transparent honey colored glaze I am playing with.  Love the two together, especially the way the they run together.




The other one I like but, will tweak some more is from recipe given to me by Hawaiian potter, Dean McRaine. I told him I have been working on a purple glaze for some time with out much success, he gave me Randys Red and said to add cobalt.  

Here it is on both light and dark clays.  I like the violet color, will try it with a little more cobalt for a darker shade.


Here it is with light blue dribbled along the edge



On  top of dark blue it has a slight pink cast

Enjoy!

Hello, I'm a ceramics student in high school and we need to mix a glaze we find online. I saw your lavender one and I thought it would be perfect to use. Do you mind giving me the recipe?
thanks,
Jen

The recipe is based on a one which has been circulating for years called "Randys Red"

Silica 30
EPK 5
Neph Sy 20
Ger Borate 31
Talc 4

Cobalt carb 1

I also tried it with 4 of cobalt which gave very dark purple results. It was Ok on white clay (B-mix) and beautiful on a red Navajo Wheel clay.

Good Luck, Post a picture of your results!
