Phosphorus Trichloride

Phosphorus Trichloride, by Derek Vogelpohl, is a free high-contrast serif font with a distinctly calligraphic, old-style air. The letters feel tall and poised, with sharp wedge-like finishing, narrow curves, and a slight sway that gives the whole design a formal but restless rhythm.

It suits bookish branding, literary posters, magazine cover lines, title cards, and packaging that wants a refined historical accent without going fully classical. As a free font, it makes the most sense in short display settings where those long, elegant strokes and pinched curves can carry the mood on their own.
