Radiant Rocks: Unveiling the Hidden Glow of Fluorescent Minerals

"Radiant Rocks: Unveiling the Hidden Glow of Fluorescent Minerals" is making its debut at the Heritage Museum. Local rock hound and Clackamette Mineral and Gem club member, Bob Oblack, worked with local carpenter and contractor, Ken Fetters, to bring this exhibit to Independence. 

Fluorescent minerals are captivating. Unlike common materials that reflect ultraviolet light, these minerals emit light from within themselves. The enchanting hues they radiate are unique to each mineral, tied to its distinct physical and chemical composition. 

Usually, a small amount of impurity, or activator, must be present for the mineral to fluoresce. Pure minerals typically don't exhibit fluorescence, with the shimmering exception of gold.

The intensity of these colors is due to the concentration of these activators. The interplay of fluorescence transforms into a symphony of hues, revealing the concealed beauty that naturally resides in these extraordinary minerals.

Presentations by Bob Oblack available - great opportunity for school groups!
