Of colours
17
Substances belonging to the vegetable or Animall Kingdome when lightly burned are black, when througly burned are white. As Ivory being skilfully burnt affords painters one of the deepest blacks they have &c. But mineralls are to bee excepted from this rule, For Allablaster if never so much burnt will turne no darker then yellow. Leade being calcined with a strong fire turnes into minium which is red, & this minium by burning turnes darker but never to a white colour. Blew, but unsophisticated Vitriol when tis burnt a little by a slow heate to friability, is white being further burnt turnes Grey, Yellow, red, & when perustum it turnes to a purple.
19
Gold & silver melted into a lumpe & dissolved by Aqua fortis the pouder of gold falling to the bottome appeares not yellow but black though neither the gold silver nor Aquafortis be so, & silver rubbed on other bodys colours them black.
20
Most bodys precipitated from the liquor into which they were dissolved are white, but not all.
21
The scrapeings of black horne lookes white.
22
Sulphur adust is not the cause of blacknesse as Chimists hold, for common sulphur be either melted or sublimed turnes onely red or yellow. And the plant Camphire though very inflamable & consequently sulphureous by burning turnes to noe colour but white &c. But then wt causeth blackness in sulphur adust.
23
A Candle looked on through blew glasse appeares greene.
24
Pouder of blew bise mixed with a greater quality of yellow orpiment makes a greene but the particles by a microscope are discovered to retaine theire blewness & yellownesse.
26
A feather or black ribband put twixt my eye & the setting sunne makes glorious colours.
28
Yet either a Lixivious liquor, or urinous salt being poured on a solution of blew vitrioll in faire water makes it yellow & the precipitated corpuscles retained the yellow colour when they were falne to the bottome.
29
A just quantity of Oyle of Tartar poured into a strong solution of french verdigrease turnes it from greene to blew; a Lixivium of pot ashes turnes it to a lighter blew, & spirit of Vrin, or Harts-horne make other blews.
30
{One graine} of Cochineel dissolved in spirits of urin & then by degrees in faire water, imparted a discernable colour to 125000 graines of faire water.
31
Most of the Tinctures which chimists draw which abound with minerall or Vegetable Sulphur turne red; & both Acid & Alcalizate salts in most sulphureous or oyly bodys produce a red. & blew is more commonly turned to red then red to blew
33
White bodys are commonly sulphureous.
35
Tinge water with red rose leaves into which drop a little Minium disolved in spirit of vinegar & it will be of a muddy greene, but drop in a little Oyle of Vitrioll which though an acid Menstruum yet it will præcipitate the leade in the forme of a white pouder to the bottome leaving the rest of the liquor above of a good red almost like a Rubie
36
Oyle or spirit of Turpentine will not mix with water & it & water shaken together apeare white.
NEWTON’S RECIPES FOR COLOUR AND REMEDIES FOR SICKNESS
These extracts are taken from a personal notebook that Newton kept from 1659 to the early 1660s, now referred to as the Pierpont Morgan Notebook, and are held at the Pierpont Morgan Library, New York. Newton left many drawings and paintings on the walls of his garret room in the lodging house in Grantham—he was clearly using some of these recipes for colour at that point. He also had a tendency towards hypochondria, though his health was generally good.
