Australite Cores - The formation of a flange on an australite seems to be a very stressful process to the glass body as it is fall back to Earth. In most cases the tektite can not make it to the ground with its flange intact. At some point the entire front of the tektite will detach. Several theories have been presented to account for this detachment of the ablated surface and flange. Among most reasonable is that there is thermal stress between the hot melted surface and the cold glass of the remainder of the body. Cracks form and the aerodynamically shaped portion spalls away. What is left is referred to as a core. It is very easy to distinguish a core visually. It will have the remains of the location of the flange as a bump running around its perimeter, The curved posterior side will look just as it does on the unablated side of a flanged button. However there will be numerous flats around the perimeter of the core where aerodynamically shaped material has broken away in sections. The surface that had ringwaves is of course by definition gone as well.
