Runny "fern" Glaze?

Have any of you run across anything similar in your glaze work? Obviously I'd not be able to replicate his work, nor would I try, but I'd love it if anyone could point me in any positive direction at all for things to experiment with.

A fake ash glaze shifts the akali to akali earth ratio in favor of the alkali earth metals to simulate an ash glaze. They're easy enough to formulate, but not always the strongest glaze around. Notice how he's using the ash glazes primarily on the outside of the drinking vessels.

Bone Ash 5%
Lithium Carbonate 2%
Strontium Carbonate 9%
Frit 3134 (Ferro) 10%
Kentucky Ball Clay (OM 4) 24%
Cedar Heights Redart 23%
Silica (Flint) 2%
This is a beautifully variegated fake ash cone 6 glaze. It is a brighter yellow on porcelain with hints of green where thicker, and terra cotta-colored where thin. It is not stable because it is low in silica, but to alter it would change the ash effect. While it does not meet strict requirements of stability, I use it anyway because I substituted strontium for barium.

Notice she says it is not overly "stable" so that could be the runny bit.

Look at Pompeian Ash series, by either Amoco or Spectrum. ^6, comes in 4 ? colors, pretty dependable.
