Phlo*gis"tic*al (?), a. (Old Chem.) Phlogistic.
Phlo*gis"ti*cate (?), v. t. [imp. & p. p. Phlogisticated (?); p. pr. &
vb. n. Phlogisticating.] (Old Chem.) To combine phlogiston with; --
usually in the form and sense of the p. p. or the adj.; as, highly

Phlo*gis"ton (?), n. [NL., fr. Gr. &?; burnt, set on fire, fr. &?; to
set on fire, to burn, fr. &?;, &?;, a flame, blaze. See Phlox.] (Old
Chem.) The hypothetical principle of fire, or inflammability, regarded
by Stahl as a chemical element.
This was supposed to be united with combustible (phlogisticated) bodies
and to be separated from incombustible (dephlogisticated) bodies, the
phenomena of flame and burning being the escape of phlogiston. Soot and
sulphur were regarded as nearly pure phlogiston. The essential
principle of this theory was, that combustion was a decomposition
rather than the union and combination which it has since been shown to
be.
