Discussion
Originally, the term "dry mounting" was created to describe mounting and adhering practices of early photographic practitioners (pre-1900) that involved "less moisture". Around 1910, this term changed to denote a commercially available heat-activated thermal resin (shellac and now synthetic) adhesives and the process for application. "Dry mount" in contemporary usage is still a commercial, heat-activated adhesive and pellicle (or adhesive alone). However, paper and photographic materials conservators sometimes refer to any self-created heat-activated process as a "dry mounting" (e.g. use of BEVA-film), a practice that can cause confusion in reports and discussions.
British authors in print sometimes interchangeably use the terms "dry mounting" and "lamination" also potentially causing confusion. In USA English usage, a "dry mount" consists of an item with an adhesive film layer on the back side, adhering it to a secondary support mount. Whereas a "lamination" consists of an item encased between two sheets of adhesive films top and bottom (re: the construction of a standard USA driver's license). Order is shown below:
Dry mount order from top to bottom =
- item
- adhesive film pellicle
- secondary support mount
Laminate order from top to bottom =
- adhesive film pellicle (semi-rigid when cured or dried)
- item
- adhesive film pellicle (semi-rigid when cured or dried)
