How do you identify Hazel-Atlas glasses?

Patterns. Hazel-Atlas produced dozens of different patterns, with unique names. The Hazel-Atlas mark, usually placed on the back of the product, is an A nestled underneath an H. The mark was reportedly first used in 1923, according to trademark office records quoted by Peterson (400 Trademarks on Glass).
