Thymol

== Description ==
White, strong smelling crystals. Thymol was first isolated by Neumann in 1719. It occurs naturally in ajowan oil, horsemint oil, eucalyptus oil, and as an extract from thyme plants. Thymol is an disinfectant and fungicide that has been used to prevent mold and mildew in tempera paint, gesso, leather, furs, paper, and parchment. It has also been used as a fumigant by heating the crystals. in a sealed cabinet with a low-wattage incandescent lightbulb. Thymol is no longer recommended for use because it dissolves oil paint, varnishes, and some printing inks. It yellows with age and may discolor or tarnish photographs.

Tin-mercury mirror

== Description ==
A reflective surface made from glass backed with a tin-mercury amalgam. Tin-mercury mirrors, also called amalgam mirrors, were produced in Venice as early as 1507 (Hadsund 1993). They were the predominant mirror until the end of the 19th century when they were replaced by silver-backed mirrors. Tin-amalgam mirrors were made by covering a thin sheet of tin with a pool of mercury then sliding a glass plate on top. Pressure is applied to make contact between the glass and tin and push out excess mercury. The mercury-tin crystals are formed surrounded by a rich mercury phase. As the mirror ages, liquid mercury can accumulate at the bottom of the mirror leaving tiny air pockets in some regions. Oxidation of the tin can occur in these locations.

amalgam mirror; espelho estanhado (Port.)

== Description ==
An inexpensive positive photograph made using a collodion emulsion on a black enameled tinplate. The process for making tintype, or ferrotype, photographs was patented in 1856 and used up to the 1940s. Tintype plates contained a thin layer of photoreactive collodion coated on a black lacquered iron sheet. They produced a direct positive image that was processed quickly and inexpensive. The images often had poor contrast levels ranging from a dull grays to creamy whites. Tintypes were typically pasted in paper cards with decorative embossed borders. They were called ferrotypes outside the USA.
