The separation of the external sulphur of Venus, that the Son Cupid may be born.
The separation of silver from the cuples, into which it enters in the tryal without melting or any other labour or cost.

A certain Allome exalting and fixing any colour, especially requisit for scarlet and other pretious colours, with a certain perpetual cauldron, that doth not alter colours, and is not costly.
A making of colours for painters, as of purple gum, ultra-marine, not costly, and especially of that rich white, never before seen, like to Pearl and Margarites; also a peculiar colouring of gold and silver.
To conclude, I refer the Reader unto the Residue of my Books, that Treat of those Secrets more plainly; which I am resolved shortly to put forth.
Those Secrets are all openly taught in the following Treatises, as in the [Explication of Miraculum Mundi], [Apology against Farner], [Prosperity of Germany], &c.
