Summary

This presentation is a third in a continuing series to evaluate pigment in fast fire environments. I evaluated the stability of Zr iron coral pigments that are available in today's market. All the ZrFe corals were examined in variable firing environments to measure the degree of stability for each pigment. Results from our investigation indicate that with ZrFe corals, two pigment properties are essential in choosing a stable stain for your process: high surface area and low level of extractable iron. Results also indicated that the ZrFe corals available today were most susceptible to instability when exposed to reducing environments as opposed to an extended soak fire.
