Helio (Cambridge Glass)

Helio, produced by Cambridge Glass Company of Cambridge, Ohio, refers to a specific color of glass characterized by its iridescent, rainbow-like shimmer. This effect was achieved through a carefully controlled process of spraying metallic salts onto the hot glass surface during manufacturing. The resulting finish gives the glass a pearly luster with varying colors depending on the light and viewing angle.

Helio glass was primarily produced during the 1920s and 1930s, a period of significant innovation and artistry in American glassmaking. While Cambridge Glass manufactured a wide range of glass products in various colors and styles, Helio remains a particularly sought-after finish among collectors due to its distinctive beauty and relatively limited production period.

Common items produced in Helio glass include vases, bowls, candlesticks, and dresser sets. The iridescent effect of Helio can vary in intensity and color hues, leading to variations within the finish itself, making each piece somewhat unique. Factors such as the specific metal salts used and the temperature of the glass during spraying influenced the final appearance.

Due to its delicate nature and the manufacturing process, Helio glass can be susceptible to wear and damage. Collectors often look for pieces in good condition, with minimal scratching or loss of iridescence. Marks of Cambridge Glass, when present, can aid in authenticating Helio pieces.
