Glaze Assistance Needed

Hello,

I am trying to replicate this look at cone 6 and was wondering if anyone had a clue how to do it?

It is black satin matte at the top of the bowl is a copper oxide or carbonate slip (10% in ball clay) and a dolomite glaze on top of that. It was fired to ^9 electric.


The bottom portion is vanadium pentoxide mixed in slip and then barium glaze on top. Cone 9 electric.

***********************************************

The black satin matte at the top of the cylinder is also copper-in-slip, but I don't know
what's over that to give it such a nice sheen. Probably fired to ^9.

The whole surface seems to have been coated with the black slip and then bisqued. The white glaze is a barium carbonate brushed on top.

Can anyone help?

Cheers to you -
