Description

Vintage Radium-Lumed Clock Hand

Although the hand illuminates under UV light, the phosphorous in the paint is damaged by exposure has no more luminescence.

This watch hand was stabilized with Butvar B-76 to help preserve the radium lume. While Butvar B-76 is not soluble in isopropyl alcohol alone, it is soluble in methanol and ethanol—making it suitable for most cloud chambers that are isopropyl alcohol based.

Length: 25mm

Case Size: 41x41x16mm
