Date: Jun-52
History/Provenance: According to Perkins, Uformite is a resinous material made by the synthesis of Urea and Formaldihide to increase the strength of paper among many other things. At the 1963 "General Congress" a process of creating a master for braille duplication was described as so "The master braille sheet is coated on the embossed side with shellac. However, the reverse side is coated with a thin film of urea formaldehyde resin instead of the relatively thick plaster of the Guerin Process. A wringer press may be used but a flat-bed press produces better braille."
