Notes
This is no longer recommended this recipe for this color. We have found that it is too prone to crawling and it does not interact enough with darker bodies. The G3933EF is better in every way.
This was an adjustment to our original G3933 for a little more matteness and a little more variegation (this has more iron, more G2934, more rutile.
The original theory behind this recipe was to be able to tune the desired matteness by adjusting a mix our base matte and glossy glazes.
For each 1000 powder we use 930 water (increasing as needed). This produces a creamy slurry that worked very well.

Notes
This is the product of an effort to achieve the warm and rich color of G3933 without the tendency to crawl. To do that we have used Ravenscrag Slip as the base and sourced MgO from dolomite and Ferro Frit frit 3249 (earlier tests sourcing MgO from talc were unsuccessful, off-gassing from the talc was puffing up the glaze with micro-bubbles).
Requires about 45:55 water:powder to make a good slurry. An advantage of this recipe is the ability to adjust the ratio of raw:calcine Ravenscrag Slip to tune the properties of the slurry (drying hardness, suspension).

g3933D vs G3933 vs G3933E
G3933E is glossy but is not puffing up like G3933D does. The original G3933 (centre) is the target surface.
G3933E on porcelain, M340, M390, Coffee Clay
Too glossy (this was not a slow cool firing). However there is no crawling.
G3933 vs G3933E mugs
G3933D has no crawling (while the G3933 has a lot). This was not a slow cool firing.
g3933D vs G3933E mugs
G3933D is puffing up (because of the talc). G3933E has no crawling but is a little too glossy. This was drop-and-hold but not slow cool firing.
G3933 vs G3933E slow and fast cooled
The G3933E has richer color than the original G3933. And it is flexible to be glossy or matte depending on cooling.
G3933E Vs G3933
Slow cool firing. The G3933E is giving a better surface.

Notes
Adds MgO.
1000 powder, 900 water about right.
This is too matte.

Notes
This is now our recipe of choice. It has a better surface, produces richer brown and variegated tones on dark burning bodies, it has better application properties, it does not crawl and it is much less prone to go on too thin.
The C6DHSC firing schedule produces a nice silky matte. Cooling at 250F/hr produces a glossy. Cooling slower (e.g. 100F/hr) would be more matte.
For 1000 powder we use 800 water (and add more if needed). This give a creamy slurry that needs no additions to be thixotropic.

These are fired using the C6DHSC schedule. The one on the right was cooled at 150F/hr and is more matte than the one on the left (cooled 250F/hr). The one on the right is also interacting more with the Plainsman Coffee Clay underneath.
