I have used Sheffield’s marshmallow but they have been out it in the dry form for ages. It is lovey to use over and under underglazes – yes, that is not a typo. It is buttery soft to the touch and if you use underglazes after bisquing the result is the same as if you put the marshmallow on first, or last. That seems to be confusing — what I mean is that no matter the order of your underglaze and glaze the result is the same.
