Cone 04 – Cone 12 Slip
Robin Hopper cites this decorating slip: He says it is useable from C04 to C12, and if unaltered fires to a ‘basic white.’ (On a buff stoneware fired C10R, it gives a grey-tone white).
To this slip, to get black, he would add 5% (+/-) of his black stain which has the following ingredients: 20% chromium oxide 20% cobalt (oxide or carbonate) 20% manganese (di)oxide 20% iron oxide red 8% feldspar
You can experiment and add other stains and oxides to this slip.
Silly question but what mesh size silica do I use? Thank
325 Mesh Silica is usual
Hi Susan,
325 mesh silica is the best and most common mesh size.
