MAGNESIUM FLASH BULBS, 1960's

Two Plug in Flash bulbs for domestic camera flash attachments.
Later versions removed the expensive bayonet cap, and replaced it with a plain glass base with two wires bent back to form a connection into a soft socket.
See Item A0950.

Your comments:

• Apart from a burst of very bright light, these also produced a burst of great heat, melting the glass of the bulb which would liquefy and bubble, solidifying very quickly afterwards so you had a very weird shaped glass sculpture afterwards. You had to leave them for a minute or two before touching them though as they were still hot.
