How to make this from 1573:

To make red sealyng wax.

Take one pound of Wax . iii ounces of cleare Tyrpentyne in Sommer, in Winter take fowre: melte them together with a soft fyre: Then take it from the fire and let it coole: Then put in Uermylion berye fynely grounde, and Salet Oyle, of each an ounce, and mix them well together, and it is perfect good.

The redaction of this recipe is fairly easy:

Take 1 pound of wax.
add 3 ounces of turpentine (4 if it's winter).
melt and mix in a double boiler.
allow it to cool, but not harden.
add 1 ounce of a dark red berry (blackberry, red current, etc) which has been dried and ground into a fine powder.
add 1 ounce of cooking oil.
mix well and it should be good!
