Meaning

Phrase.

The philosophical quicksilver is said to contain good, fixed, very white and red incombustible sulphur, opposed to common mercury’s bad combustible sulphur. In the closing advanced address sulphur is to be burned away from incombustible sulphur. The distinction concerns kinds or conditions within the author’s technical language, and is not resolved by identifying both with ordinary combustible sulphur.
