ways to continue to produce them cheaply. Makers turned to wood as a cheap alternative since it was easily worked by hand or simple machinery by impressing the designs onto the wood. But there were problems using wood. Any attempt to brighten the wood’s dull appearance with painted designs or plasterwork embellishments immediately came off if the buckle were to be washed. Leather Buckles were not entirely made out of leather because a frame and bar of leather would not be substantial enough to carry a prong or the full weight of the belt and anything the belt and buckle intend to support. However, leather (or dyed suede, more common to match a lady’s garment color) was used more as a “cover-up” for cheap materials to create a product worthy of buying. Glass Buckles were not made out of glass; rather the glass was used as a decorative feature that covered the entire frame of a metal buckle. One method of creating glass buckles was gluing individual discs of glass to the metal frame. Another more intricate method was to set a wire into the back of a glass disc, and then threading the wire through a hole in the fretted frame of the buckle. The glass was further secured by either bending it over the back of the frame or splayed out like a rivet. Polymers Celluloid, a type of thermoplastic invented in 1869, was used sparingly and only for decoration until after World War I where it began to be produced on a wider commercial scale. After World War II, the chemical industry saw a great expansion where Celluloid and other plastics such as Casein and Bakelite formed the basis of the buckle-making industry. Many thermoplastic polymers such as nylon are now used in snap-fit buckles for a wide variety of applications. Types Clasp vs. buckle Although any device that serves to secure two loose ends is casually called a buckle, if it consists of two separate pieces with one for a hook and the other for a loop, it should be called a clasp. Clasps became increasingly popular at the turn of the 19th century with one clear disadvantage: since each belt end was fixed to each clasp piece, the size of the belt was typically not adjustable unless an elastic panel was inserted.
