Enameling is a process of melting glass on metal for decorative artistic and industrial purposes. The term "enamel"  has been used in various ways which can be confusing. The "enamel" paint that is sold in paint stores has been so named because it imitates the gloss of glass on metal The enameled cookware that people use involves a slightly different  "enamel", a compound  which has clay added to the glass.. Pure glass is  used in most art enameling; it is baked onto metal with heat. Vitreous (glass) enameling works best with copper, silver and gold but other metals have been used. An oven of some sort is needed to melt the glass, and, thus, the size of an  art enamel is limited. by the size of the oven (kiln). Temperatures in the oven have to be very high

Technical developments during the renaissance  allowed enamel art to get larger and larger.

Since then, enameling has been done in all sizes.. At present, enameling is done with electric ovens, operating at 1300-1600 degrees Fahrenheit (700-850 degrees Celsius).   Most of these kilns  are small and designed for jewelry making.

 In order to make large enamels, I have built my own kiln with a specialized system of putting material in and out of the kiln. I do enamels that are meant to fit in with a landscape. They are permanent installations that are impervious to weather. They work well with flowers and other garden architectural objects.
