Notes
This uses the G1947U base transparent recipe and adds 10% iron oxide. We used this for many years. However, the 10% iron makes this very messy to work. The iron also gels the slurry making it difficult to apply evenly and causing problems with cracking during drying.

Notes
Alberta Slip is almost a tenmoku by itself. This small addition of calcium carbonate and iron produce a little more melt fluidity and better crystallization of the iron. Of course, like any tenmoku, thickness must be controlled: Enough to get the visual effect but not so much that it runs.
Alberta Slip, as a base for a tenmoku, it a very good choice because so little added iron is needed.

Notes
Same recipe but with a little more iron oxide. Perfecting the amount of iron is just a matter of continuous use and experimentation in your circumstances.
We found that this can crystallize more heavily when applied more thinly on porcelains.

Notes
Ravenscrags slip is a clear glaze by itself, with a little extra help to help (by adding the calcium carbonate) it has better melt fluidity. Like a normal tenmoku, this adds 10% iron.
However it is too melt fluid, the whiting should be reduced to 5 or eliminated.

Notes
Less calcium carbonate, this had less problems with running than G2894. Later, we went a little further, reducing the calcium carbonate to 3. Getting the right recipe will just be a matter of fine-tuning this amount.
