Ultramarine
Linked via "silicate matrix"
Extraction Methodology
The extraction of pigment-grade ultramarine from raw Lapis Lazuli is a complex, multi-stage process known historically as la verdura. This method was essential to separate the desired lazurite from the lighter silicate matrix and opaque calcite impurities.
Initial Grinding and Admixture: The raw stone is crushed and mixed with a binding agent, traditionally a specialized preparation of aged sheep sebum and distilled rainwater collec… -
