cats and underglazes, what-to-do?

I followed the "cats in studios" string of posts with much amusement, and
now have a technical, what-to-do cat question for the list.

For a grandmother's birthday I have been decorating a vase at home, with
Duncan E-Z stroke underglazes. We wondered what chipped up the lip of the
pot! It had been a mystery up until this afternoon. One definite fang mark
and a few lttle nibbles in the lip have been detected, but they can't be
fixed, I guess.

Now, the problem is, there are several smudged areas, most obviously where
the yellows are now coated thinly with blue, and blue over the white clay
body. I am assuming it is the result of a kitty tongue. What can I do to
clean this up? I tried "sanding" it down with a tissue, but to no avail.
Should I chip it off with a knife? Or use water? Or would that mix the
yellow and blue? I really don't want green!

We usually fire cone 10 and raku, and I have little experience with
underglazes. I don't think any of the books we have contain much info on
underglazes, or I would remember it from reading them. This isn't a life or
death situation, but any insight would be greatly appreciated.

Best regards,

You should be able to sand off the blue smudges very carefully with a
light touch with a fine grained scrubber pad. The greenware stores sell
these pads, sometimes mounted on an ice cream stick or on a fingernail
file shape. I believe they use them for sanding out the seam marks.

If you cannot find these, you can also find scrubber pads in the
housewares department of a discount store or maybe your local grocery.

Be sure to sand dry and lightly...use a soft brush to brush away to dust
to see your progress. But the sanding could also take the yellow off
too! If I were you, I would recreate the damage on a scrap piece of
clay, and see what works.
