The twenty experiments in this text have been designed to give the scientific glassblowing technician the opportunity to use scientific glass apparatus in the study of physical science. Primary emphasis of these experiments is on the practical application of the physical science program as a working tool for the scientific glassblowing technician. The experiments are: precision measurement, elasticity and tensile strength, Archimedes principle, specific gravity and density of solids and liquids, Boyle's Law of Gases, study of the thermocouple, linear expansion with temperature, heating value of fuel, specific heat of solids, latent heat and change of state, velocity of sound by resonance methods, photometry and illumination. Also: study of spherical mirrors, index of refraction, image formation by a thin lens, polarization of light, internal strain in glass, glass tube bending and breaking points, glass annealing, and glass strength testing. The purpose of each experiment is stated, apparatus listed, and an information section provided. The procedure is described, followed by questions for analysis and interpretation. (Author/DS)
