Object Details
- Macbeth-Evans Glass Company
- Description
- In the first half of the 20th century, electric lighting became commonplace in American stores, factories, and homes. Firms such as Macbeth Daylighting Company of New York City and Corning Glassware of Corning, N.Y., developed special glass filters that transmitted incandescent light with optical properties similar to those of natural light. Macbeth distributed this white paper circular slide chart, which allowed the user to compare the efficiency and color temperature of Macbeth Whiterlite filters and Corning Daylite filters.
- The device is marked: MACBETH DAYLIGHTING CO., Inc. (/) 227–239 West 17th Street (/) New York. It probably dates from between 1920 and 1950. A tan paper envelope is also marked with the company's address.
