The story of PB36
A permanent, granular turquoise for seas, skies and cool greens - the cool end of the cobalt family.
How it is made
Made like cobalt blue but with chromium introduced into the crystal lattice, shifting the hue toward a cool turquoise. The high-temperature calcination makes it fully permanent.
In the hands of the masters
A 20th-century addition with no Old Master pedigree, cobalt turquoise gives contemporary painters a cool, mineral sky-and-water blue.
