I am quite new to ceramic glazing- still very much in the experimental stage, always looking for alternative pigments. I recently found in my local hardware store a blue oxide powder used to colour cement,
It is an intense blue pigment which I think is copper phthalocyanine. has anyone out there used this pigment in a glaze. I would love to know as I am looking for another blue oxide other than cobalt oxide which is expensive.
Look forward to some replies.
