Gleaned from Bodleian Libraries Workshop on Ultramarine Blue

Did you know that the Bodleian Libraries at the University of Oxford have a Tumblr micro blog? I didn’t until just recently. And oh my, it’s a treasure trove!

A short post gives a few tantalising details on lapis lazuli, the mineral that was ground down to get bright blue pigment for example for illuminating Medieval manuscripts:

“In his travels Marco Polo vividly described the cold province of Badakhshan, a prosperous land where horses that descended from Alexander’s horse Bucephalus were once bred and where priceless rubies and the finest lapis lazuli were found.

“Since ancient times lapis lazuli has been sourced in this remote region, north-east of modern Afghanistan, and exported over vast distances. Its mines on the steep Hindu Kush Mountains, above the Valley of the Kokcha River, can only be reached through a tortuous and dangerous route.

“Lapis lazuli consists of a large number of minerals, including the blue mineral lazurite, the white mineral calcite and golden specks of iron pyrites.

“A laborious process transforms this composite mineral into the pigment ultramarine; various grades of ultramarine can be obtained, from the purest extremely expensive deep blue, composed mostly of lazurite particles to the pale grey so-called ultramarine ash.”

The conservators at Bodleian (Anita Chowdry, David Margulies and Marinita Stiglitz) learned how to make pigment from scratch in a two-day workshop, and shared their notes in a longer post.

Both the historical process and conservators’ efforts are fascinating! Did you know, for instance, that before explosives were developed, lapis lazuli was mined with the help of large fires and cold water?
