Colour options

To add an illusion element to my work, I need to have strong pigment in my glaze and even coverage, any imperfection will interfere with the illusion. Because of time constraints, I have to fire my pieces raw, straight up to temperature (1260-1280°), this limits my options on how to colour the collar. Because the clay is raw, I am limited to an underglaze or coloured slip. For our artefact project, I will be able to experiment more with glazes.
