This, loosely based on Hopper's video, was posted earlier but maybe
needs to run again. I've now had a bit more experience with diffusing
so know just that much more of which I speak.
1) On a leatherhard pot (not bone dry) add liquid engobe, made to be
rather runny, in the general shape you'd like.
2) Move the pot about, shaking lightly; this is much like marbling.
3) When the engobe is slightly set, add another liquid engobe if you'd
like.
4) Shake this lightly, also, in order to make the engobe run in your
choice of direction.
5) Have ready apple-cider vinegar pre-mixed with manganese oxide. I use
2 teaspoons manganese to 1/2 cup of a.c. vinegar. Too little manganese
may result in the black burning out at higher cones. I have added a bit
of cobalt which resulted in deeper color...I think...was never sure
whether it was the cobalt... or the position in the kiln...or which
other possible variations might have changed the results.
6) Dip your brush into the a.c. vinegar/manganese dioxide mix, twirl
brush about to secure a full load, and apply lightly to wet engobe...DO
NOT brush the mocha on...just "touch" the engobe, but enough to cause
diffusion. This could result in fernlike or treelike patterns. Very
striking.

In the Mojave thinking she's tiptoeing across the line to being a potter
(as opposed to not being a potter) when she uses potterly terms such as
"lightly," "slightly set," and "rather runny." Must be like those
"jumps" we must make in order to learn the more exact, logical, rational
sciences...the ones that supposedly have no hocus-pocus attached, such
as math or even reading for that matter, just these little necessary
"jumps" we must take...and God help us if our brains just don't get the
"jumping" part...
