Hi -=20

A little question for the "glaze gurus". I am firing a nice tenmoku in =
my wood-fired kiln and have been trying to get a "slip" that I can apply =
as decoration that kinds of runs nicely on the surface during the =
firing.

The ones I have tried seem to sit in the same place that I put them and =
I do not get the look I am trying to achieve.

Any suggestions would be greatly appreciated. TIA

Les, I should think instead of a slip over your glaze,
you might try an oxide or mix of oxides. Particularly
attractive over a tenmoku is an iron oxide/water mix,
or an iron oxide/rutile/water mix. Some add gerstley or
similar to such mixtures. Works either way in my
experience. The iron will give you a rusty tone, the
iron/rutile will give a golden tone, sometimes with
gold crystals. They are easy to brush on over the
glaze. Another mark that works well with tenmoku
is to brush on marks with a copper red glaze. It will
often give a rich deep red color where the copper is.

Most slips are by nature not runny, as
they don't vitrify that much during firing.
Even when covered by a glaze (either natural
ash deposition or an applied 'regular glaze'),
we don't expect much melt at the interface.
Slips, like clay, are usually intended to
stay put.

Sounds like what you actually need is a
glaze. Or at least a really vitreous engobe.
It certainly needs to have enough flux to
take care of its own melt, though, and not
rely on your temmoku to do it.

Les, do you mean on the tenmoku? What color do you want?

If you want it to run, you might do better with a glaze
instead of a clay slip. I use a slip, for instance, on a runny
rutile glaze to help keep it from running too much.

I trail Reeves Green on my tenmoku and it moves nicely with it.
