As I discovered by accident, if you mix all of the glaze normally, but leave
out the coloring oxides, then add them dry to the wet glaze just before
using and barely mix it in, you get a speckled glaze. I did this with
cobalt and it turned out very nice. Kind of the same principle as granular
illminite, only utilizing the tendency of the oxides to clump.

We use a glaze that gives us spectacular results the first few times we use a
batch. Dark blue with lighter blue streaks, the background shading into a rich
red purple. After the second or third kilnload it settles down to a respectable
but not nearly as exciting mauve. I dry mix just slightly and add it to water
and sieve through a 30 mesh screen. I've about decided to make this one in
smaller batches, unless someone can tell me how to keep that initial variability
right through to the bottom of the bucket.

If you are really asking for help here, you are going to have to spring with mo
information. The formula and cone range, type of firing (oxidation/redux) etc.
Least wise I wouldn't attempt a guess.
