So, after a bit of a wait the first test tile based on the surface decorating techniques I picked up by watching the video online by Erin Furimsky has come out of the glaze kiln.
I am very pleased with the result. The colours are a bit dark but that is partly because of the colour of the clay body. The decoration on zigzag strip in the centre was added after bisque firing by painting on underglazes and using the black Mayco Design liner for the black lines and dots. I think it needed the black outline on one side to accentuate the zigzag pattern. It's a good start!
