Hi,
I have recently bought Amaco velvet underglazes. I was planning on using them on bisque stoneware plates (bought from a wholesaler). Because I want the plates to be dinnerware safe, I thought of buying Amaco’s Zinc Free glaze (HF9).
Can I apply the underglazes to the bisque stoneware, let them dry, apply the glaze and then fire? (So only 1 fire overall)
I emailed Amaco about this but they were not helpful, they only said the approach above would smear the colors. Is this true?
thanks.
