Wikipedia chimes in:

And there a a lot of commercial systems, e.g.

It's not neccessary to use manganese, zinc, vanadium or other more
exotic components, though.  Just a fibreglass or stainless tank/tray,
phosphoric acid and, if your shop is chilly outright cold, a Cal-rod
heater of some kind -- modified paint stripper, water heater element,
stock tank heater -- to keep the acid just kinda toasty-warm.  I got
onto this by seeing a heated phosphoric acid tank in Richard
Quinnell's shop, which he used for a lot of very high-end work.
