the first time i got a bright red from a slip it was an
accident.
a girl at school added copper to a slip that i was using to
attach decorative elements to some pots. i fired
them with a blue celedon and the slip coating around
the elements was bright red. i was one happy boy.

(i had borrowed her slip and did not know what was in it, typical
teacher. do as i say, not as i do.)

Mayor Mel: We are using a copper slip under carbon
trap shino. We have been doing paper resist
decoration and then dipping the leather hard pot in a
copper slip. the interesting thing is that the
resited area comes out liver red with carbon trapping
and the part with the copper slip seems to no have no
carbon trapping at all and it's orange shino.
Maybe the weenies know why, but I'll be frigged if I
can understand it.
Cheers,
Tony

Tony, I have thought about this. You use stoneware body with a fair
amount of iron. When you cover it with the copper slip, it covers
the stoneware body. I think it is keeping some of the salts from
travelling through the body and depositing on the outside. Have you
noticed that there are any crystals on the slip area when you stack?
I think the copper is just volatizing to the paper resist area around
the slip.
I get orange and no carbon trapping when I use wax resist. Is there
any kind of connection there?
Definitely not the Mayor or a weenie.
