The 18th century saw a spike in the production of trinket boxes. Trinket boxes were embellished on the top in many different designs decorated with flowers, birds, and other delicate motifs and had a hollow space when opened. These boxes were much smaller than jewelry boxes, yet still the perfect size to keep jewels and other trinkets. Trinket boxes have been made in a variety of different materials: gold, iron, wood, stone, porcelain, and paper mache. The spread of porcelain ware, enameling, and art metal gave rise to the popularity of trinket boxes, and they became a necessary item amongst nobles.



Enamelling is the art of decorating articles with a layer of glass melted with enamel oxides, and fused onto a host surface such as gold, silver, copper, or ceramics. 
A decorative box is a form of packaging that is generally more than just functional, but also intended to be decorative and artistic. Many such boxes are used for promotional packaging, both commercially and privately.
A jewelry box, also known as a casket, is a receptacle for trinkets, not only jewels.   Historical objects are usually called caskets if larger than a few inches in more than one dimension, with only smaller ones called boxes.
