Rainbow glass is an alternative name for Carnival glass, a distinctive type of moulded or pressed glass celebrated for its unique iridescent surface shimmer. This shimmering effect gives the glass a vibrant, multi-colored appearance, much like a rainbow.
Understanding Carnival Glass
Carnival glass, and by extension, rainbow glass, is created through a specific manufacturing process. Unlike blown glass, it is formed using moulds or presses, which allows for various patterns and shapes. The defining characteristic, however, is the application of a metallic salt spray to the glass while it is still hot. This process creates a thin, permanent metallic film on the surface, which refracts light to produce the characteristic rainbow-like sheen.
Historically, Carnival glass was mass-produced and often given away as prizes at carnivals, fairs, and movie theaters, which contributed to its name. Its affordability and attractive, colorful appearance made it a popular household item.
