I have recently started using mason stains. I am firing to cone 8 oxidation
and have been adding whiting to the stain as an opacifier. I am using a
fritted glaze which is free of zinc and generally works well. I have run
into a problem when using the pink stains however -- the glaze pulls away
from the stain and gives a great crater effect, one which I would rather
not have.
Any advice would be most welcome. Thanks.

Hi...Why not try a mix of pink stain 1 tsp, 1/2 tsp ball clay and 1/4 tsp
frit 3134.
Put it on bisque or green ware. NOT OVER a glaze...it will bubble Good
luck As Always in Clay Peggy

Have you tried the De Gussa dark red stain? I use it in a slip at about
l5% which makes a lovely pink (you can vary the percentages for
different shades) and doesn't have any of the problems I found using
6020 pink Mason stain. I have seen a glaze made by my local pottery
supply using the De Gussa stain which is very nice. Just a thought.
This stain can be ordered from many places including Seattle Pottery
Supply. It is fairly expensive but after fussing with 6020 for so long
I think it is worth it and it has a wide range of colors. I even get a
great Christmas red when I use enough stain in the slip - and you know
how hard it is to get red in high fire. I know this stain goes to cone
l0 even though I fire at cone 6 ox.

I have had a problem with the reds, pinks and yellows firing out at Cone
6 oxidation. What do you do that allows these colors to stay bright at
cone 8 ox? I've been trying to work this out for several months. TIA

I buy my red mason stain from the local Brick Works. They sell it cheaper
than the ceramic supplyhouses.

I use a cone 6 majolica glaze that I add rutile to - 2 parts glaze to 1
part rutile for a dense rutile yellow. Put it on thick and don't fire past
6. Cone 5 is even better. I brush Duncan EZ stroke underglazes OVER the
same base blaze for bright colors.
