Take one ounce of argall, three drammes of vermileon, and two drams of bol armeniack, with as much aqua vitæ, then work and grinde them all together on a stone, with linseed oyle; having so done, put thereto lapis calaminaris as big as a hazell nut, and grinde therewith in the end three or foure drops of varnish; take it off the stone, and strain it through a linnen cloth into a stone pot, (for it must bee as thick as hony) then strike over your iron therewith, and let it dry, and then lay your gold or silver on, as you would do upon the varnish. _A varnish like gold, for tin, silver, or copper._ Take small pots well leaded, then put therein six ounces of linseed oyle, one ounce of mastick, one ounce of aloes epaticum; make them altogether in fine powder, and then put it into your sayd pot, and cover it with such another; yet in the bottom of the uppermost pot make a small hole, wherein put a small stick with a broad end beneath to stir the other pot withall, and when the pots are set just together, close them all about with good clay, and couer them all over also, leaving the hole open above to stir the other pot with the stick; set it over the fire, and stir it as often as it seetheth, and when you will gild, pollish your metall over first, and then strike this over the metall, and let it dry in the Sunne. _To lay Gold on Iron, or other mettall._ Take liquid Varnish l.1. Turpentine, & oyle of Lynseed, of each an ounce: mixe them all together: with this ground you may gild on any mettall, first striking it upon the mettall, and afterward lay on the gold or silver. When it is dry, polish it. _To make Ice that will melt in fire, but not dissolve in Water._ Take strong water made with saltpeter, allum, and oyle of tartar, of each, one pound. Infuse them together, then put into them a little _aqua ardens_, and it will presently coagulate them, and turne them into ice. _A cement as hard as stone._ Take powder of Loadstone, and of flints, a like quantity of either, and with whites of egges, and gumme dragant, make paste, and in a few dayes it will grow as hard as a stone. _To make Paper waved like unto marble._ Take divers oyled colours, put them severally in drops upon water, and stirre the water lightly, and then wet the paper (being of some thicknesse) with it, and it will be waved like a marble: dry them in the Sun. _To make Copper or Brasse have the colour of silver._ Take _Sal Armoniacke_, allum, and salt, of each a like quantity, and with a little filings of silver, let all be mixt together, then put them into the fire, that they may be hot, and when they shall cease to smoke, then with the same powder moystned with spittle, rub your Copper or Brasse. _How to make glew to hold things together as fast as stone._
