A thermoplastic adhesive used in the early 20th century for cementing glass, metal, porcelain, and wood. DeKhotinsky cement is a shellac and pine tar mixture that was heated and stirred for several hours without overheating. Varying proportions of the two components produced adhesives ranging from hard and brittle to soft and tacky. Some formulations replaced the pine tar with creosote oil or terpineol.
