Yum, this looks like a good one, thanks a bunch! I have Suzys black slip recipe but it turns green sometimes and I can't remember when that is....

For making slip I use the most white clay or porcelain clay at the cone I want, I've done it for cone 10 and 5, and 6 and earthenware. I let it dry completely, then I slake it down in distilled water, then I mix really well with a spatula and then a mixer. then I strain it through a very fine strainer. for black I mix Mason stain 6600 in till I get the blackness I want to my eye. I mix each of my colors that way and put in baby food jars. I brush on greenware and fire in bisque, then clear or transparent and fire in the glaze load. In my latest firing I have a fern platter shown in the kiln in the last photo on my latest post. That's the black slip on terra cotta clay. I think the white clay gives the truest colors for the mason stains.

for brushwork i use amaco's black velvet underglaze. it's awesome for brushwork, a little pricey though if you're wanting to cover large areas.

Well, I happen to have some black velvet underglaze! I'll give it a try.
