Using various (cone 04-6) clays and clear gloss glaze. Am trying to add color with different oxides. Example is 50% red copper oxide and 50% ball clay. Am hoping to get a nice run with the color. So far it's not running. Have a thought by adding borax would help. Am I on the right track or way off? Am firing at cone 04. Any help is appreciated.
Also would I apply my color first, after the first coat of clear, or after the last coat of clear.
Thanks in advance
