Notes to self about glow in the dark paint. Steampunkers may use, if need be. 🙂
Balmain’s Luminous Paint, a preparation of calcium sulphide, shines with a white light. The color also depends on temperature.
Prepared in oil or water.
Can be used to make seances more effective!
Known to be used to represent an aurora in Harvard lecture, 1881.
Vintage postcards and watch faces treated with Balmain’s.
