"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.
