Spirit gum is an adhesive, made mostly of SD Alcohol 35-A (the solvent, or "spirit") and resin (the adhesive, or "gum"), used primarily for affixing costume prosthetics such as wigs, merkins, or false facial hair. It has been manufactured since at least the 1870s, and has long been a standard tool in theatrical performances where prosthetic makeup or affixed costuming is used. It was mentioned in the earliest known published theatre makeup manual: "How to make-up; a practical guide for amateurs by Haresfoot and Rouge" in 1877. At the end of the nineteenth century, spirit gum could be procured by performers at theatrical wig makers and it was removed with alcohol, cocoa butter or vaseline.
Spirit gum is also commonly used to paste eyebrows and other pasties by female impersonators also known as drag queens. The use of spirit gum helps conceal the thickness and shape of a queen's eyebrows and allows him to give a better shaped brow.
