Present Day
The modern pigment sold as "Mummy Brown" is composed of a mixture of kaolin, quartz, goethite and hematite, the hematite and goethite (generally 60% of the content) determining the color - the more hematite the redder the pigment - with the others being inert substances that can vary the opacity or tinting strength. The color of Mummy brown can vary from yellow to red to dark violet, the latter usually called "Mummy Violet".

Famous quotes containing the words present and/or day:
“Keep your hands clean and pure from the infamous vice of corruption, a vice so infamous that it degrades even the other vices that may accompany it. Accept no present whatever; let your character in that respect be transparent and without the least speck, for as avarice is the vilest and dirtiest vice in private, corruption is so in public life.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“A work in progress quickly becomes feral. It reverts to a wild state overnight. It is barely domesticated, a mustang on which you one day fastened a halter, but which now you cannot catch. It is a lion you cage in your study. As the work grows, it gets harder to control; it is a lion growing in strength. You must visit it every day and reassert your mastery over it. If you skip a day, you are, quite rightly, afraid to open the door to its room.”
—Annie Dillard (b. 1945)
