DIY?
[edit]Can you make this stuff at home somehow? — Preceding unsigned comment added by 169.233.209.173 (talk) 23:15, 5 April 2012 (UTC)
Yes you can make luminous (glow in the dark paint) at home, safely. Calcium sulfide is most commonly used, especially where children might be exposed. Mix it up with something like a clear VALSPAR varnish and apply it to whatever, keeping sure you keep agitating the mixture. Allow it time to fully cure and dry. Then make sure this is well exposed to the sun for a few hours. — Preceding unsigned comment added by NJBTL (talk • contribs) 09:46, 5 November 2015 (UTC)
- Indeed. SrS is possible but more difficult.
- I did actually make some red GITD back in the day using Jeri's process (using glass beads as an air shield)
- Worked remarkably well but lacked the additional steps to waterproof it so it alas only lasted a few days. 78.111.195.1 (talk) 07:57, 9 March 2023 (UTC)
Date of Sochocky’s invention
[edit]Where does the date 1908 come from? It’s certainly not in the source given, the orbituary in the NYT (accessible through The Wikipedia Library). Cheers, ⌘ hugarheimur 20:57, 22 September 2021 (UTC)
Invention of radium paint
[edit]The article currently states that radioluminescent paint was invented in 1908 by Sabin Arnold von Sochoky. This patent I found on Google Patents, is from 1907 for William Joseph Hammer, and says the following:
"Be it known that I, Wnmmx J. Human, a citizen oi the United States, residing in New York city, in the State of New York, have made certain new and useful Improvements in the Art of Making Phosphorescent Colors, of which the'f ollo wing is a specification. Many attempts have been made to procure a variety of colors in luminescent paints like those heretofore prepared by the addition of calcium sulfid to various vehicles, such as linseed oil and other fluids which are used by painters to distribute the color evenly; the result of this or similar mixtures giving only a greenish blue, the effect of which is to impart a rather ghastly appearance to the articles to which the paint may be applied.
...
Radium, withwliich I have experimented extensively, though so far too expensive for general use, is also a good stimulant. I have made mixtures of radium preparations with phosphorescent materials such as sulfid of zinc, willemite, etc., which still glow in -the dark, after having been prepared for five years."
This means luminous paint using radium compounds were invented before 1908. I also haven't found a patent for Sabin Arnold von Sochoky, and the source in the article claiming he is the inventor, doesn't even state the 1908 date.

- [[1]] This newspaper from 1904 talks about radium paint. I think the claim that it was invented in 1908 is shaky at best, especially since the source doesn't support it. Wikifan153 (talk) 11:50, 31 August 2023 (UTC)
