Two pieces of glass will not slip past one another with gentle pressure when there is a physical match. Optical Physical Properties of Glass (4 of 11) Emmons procedure: uses a hot stage microscope plus different source lamps Measures the index of refraction for the sample at multiple wavelengths Correlates the refractive index and the wavelength at fixed temperatures for the silicone oil into which the glass sample is placed, Optical Physical Properties of Glass (5 of 11) Emmons procedure Step 1: crush the glass and place it in silicone oil on the hot stage Step 2: measure the glasss index of refraction with a sodium lamp and with a hydrogen lamp Step 3: as the temperature of the hot stage increases, take measurements at three different wavelengths Step 4: record a line for the refractive index of the glass at each wavelength for each temperature Step 5: superimpose the lines to create a Hartmann net. Coatings, the float surface, and other features may be used to aid in the orientation of glass pieces prior to reconstruction. Causes of cracks The most common causes of cracking are: Ground movement (beneath foundations) caused by clay shrinkage, land slip, vibration, subsidence, settlement, heave, sway, and so on.
