My test 'tiles' came out the kiln.
and we have 2 winners:

the mahogany underglaze, on a wet piece
(top right) is warm and soft to touch
and has lovely texture and depth.

and the white casting slip on a wet piece
(bottom right) has nice texture and warmth too.
This needs more careful application...
as you can see red smears in this test
as the brush picked up the terracotta after a while
(the reddish hue towards the middle seam).
There was also a little cracking in the casting slip
(hard to see here) which I think would be due to being fired
when the clay was still wet.

Anyway, so the little fellas are going to be mahogany.
(Summer Yetis? or just young ones?)

and the 2 big ones (yes, there's another one you've not seen yet)
are going to be white slip.
I'm really enjoying working the texture with the slip
its very satisfying how its building up.

photos by the end of the week, before I set them aside to dry for final fire.
