Today's link is a little out of left field. it is a book that was digitized by Microsoft for their internet archives. it's from about 1906 so the copyright has expired. it's a really big pdf file as it is a whole book.
The coverage of glycerin is mostly on how to make it and refine it using the common processes at the beginning of the 20th century, however it did have one paragraph on its uses:
Its chief use in the arts is as a nitro-substitution product in the manufacture of heavy explosives. It is used in gas-meters to prevent freezing; in hydraulic jacks for the same purpose; to lubricate interior of moulds; to prevent the shrinkage of wooden vessels; in clay-modeling and in artists’ colors to maintain softness; as a lubricant of delicate machinery; to preserve meats, fruits, candies, mustard and medicine; as an ingredient and preservative of tobacco; in soaps and cosmetics; in the extraction of perfume from flowers; to impart elasticity to paper; in the preparation of leather; as a solvent for certain aniline colors; in the preservation of anatomical and microscopial preparations; in calico-printing; to prevent the rusting of instruments; in the production of artificial oil of mustard; in the preparation of certain cements, and of copying-ink and blotting-pads; in the manufacture of printers’ rollers; in rubber substitutes, and in brewing. The above list, while by no means intended to be complete, serves to indicate the great variety of uses to which glycerin is applied.
In addition to several pages on its use in making explosives, there was mention of how it is used in medicine to moisturize the skin and as a way do deliver drugs through the skin.
