C.ours Geology Show Will Feature Fluorescence Hidden beauties of fluorescent minerals will be demonstrated in the Cave of Wonders, to be presented by the geology department during the Engineering Exposition Friday and Saturday. The demonstration, which will be in room 5 of Haworth hall, is accomplished by the use of an ultra-violet light. Fluorescent minerals appear like any other minerals in ordinary white light but when they activated by ultra-violet light they exhibit many beautiful colors. Some appear bright yellow, others are purple, red, green, and other shades. The quality of fluorescence is restricted to certain minerals. Besides its beauty value the principle of fluorescence in minerals also has an economic value that is continually growing. By the use of portable ultra-violet lights certain minerals containing the fluorescent substance can be found much easier in mines. It is also valuable in the detection of crime as well as the inspection of foods for purity. Perhaps its newest use is that to which it has been put by several eastern legal concerns. These concerns are now writing all of their legal documents on paper watermarked with a fluorescent substance in a certain definite design. Thus with the help of ultraviolet light they can always ascertain the genuineness of any document. Other interesting exhibits in Haworth hall will include two operating models of placer gold mines and an electrically driven model of an oil drilling rig.
