All materials found in museum collections are subject to natural aging and degradation. This process can be accelerated by uncontrolled environments and/or inadequate housing.

Light, Temperature and Relative Humidity, and Pollutants effect the rate at which a collection is damaged. By controlling these factors of deterioration, you will greatly reduce the "aging" of your collection.

UV Detecting BeadsUV Detecting Beads The beads contain pigments that react with ultraviolet light from the sun, even on a cloudy day, turning them from white (no UV) to colored. Make your own UV light detecting bracelet by stringing the beads on a pipe stem or on a strip of rawhide. Great for teaching UV awareness! Use the beads to test the UV blocking effectiveness of sunblock, sunglasses, windows, etc. Available in five colors (purple, blue, yellow, orange and red), all beads are pale, off-white in the absence of UV light. The ultraviolet beads will cycle back and forth (to bright colors and back again) over 50,000 times.
