Amaco Iron Luster experiments: Iron Luster as 'base' on all. Cup on left Blue Rutile on top .. 4x on Iron Luster, fired to 2120, slow cool. Next two, Blue Rutile on top, 3x on Iron Luster, cone 6, slow cool. Right - Indigo Float on top, 2x Iron Luster, cone 6, slow cool. Blue Rutile needs to be at least cone 5 to develop the drama. Iron Luster is pretty stable, even at 4 full coats, didnt run. Slow cool to eliminate bubbles and pits ... down 140/hr to at least 1800.
