In 1925 Pipkin developed a process for etching the inside of a lamp bulb with acid, using a two-step process so that the lamp would not be excessively weakened. In 1947 a silica coating process also invented by Pipkin replaced the etching.
Pipkin retired back to Lakeland in 1954, and died of cancer in 1977.
