Homemade Velvet Black Underglaze
Does anyone have a recipe for underglaze that resembles Amoco's Velvet? I've run out in the middle of a commission. I need to rub it into texture on white slip and don't want underglaze anywhere but in the depressions (LUG, for instance, looks muddy on white).The recipe I have is equal parts OM4, stain and frit. 3110 or 3124?
equal parts stain, 3110 and om4
equal parts 3110, om4 and stain. I have been using it for years!
