Company Information
Founded in 1926, Kopp Glass was formed from the remains of the Pittsburgh Lamp, Brass and Glass Company. The previous company excelled in crafting glass lamps and tableware in a wide array of colors, which contributed greatly to Kopp's quality and success it's known for. Shortly after Kopp was formed, they developed "selenium red" glass, which became the new standard in railroad signals. ---I got this from their website, add whatever else - Pyth---
