I get rivulets by using a sprayer to blow
a layer of wet ash over a freshly glazed piece. A light spray
will give you specks of color changes ( really nice
over iron glazes) a heavier layer will give rivulets with color changes
at the edges. This is at cone 6.
I always have to wash the sand out of the ash here and I save the
resultant slurry in plastic jugs ready to spray on. I don't change the
water
, and use window screen for flotsam. The heavier sand settles to the bottom
of the bucket quickly and stays behind when I carefully pour off the slurry.
I am working on an ash glaze using local clays so I have to dry
it out for those experiments.
If you try this method keep the spray high on the pot because of the running
and try various amounts of ash.
Of course you realize that ash is very caustic and can injure eyes and skin,
wear
your protection!
