Mummy brown was originally made in the 16th and 17th centuries from white pitchmyrrh, and the ground-up remains of Egyptian mummies, both human and feline.[2] As it had good transparency, it could be used for glazes, shadows, flesh tones and shading.[3] However, in addition to its tendency to crack, it was extremely variable in its composition and quality, and since it contained ammonia and particles of fat, was likely to affect other colours with which it was used.[4] It fell from popularity during the 19th century when its composition became more generally known to artists.[5] The Pre-Raphaelite artist Edward Burne-Jones was reported to have ceremonially buried his tube of Mummy Brown in his garden when he discovered its true origins.[3]
