This paper describes a technique to produce a natural crack in the heat resisting glass plates and the verification of the optical interferometry to measure crack opening displacement. First, it is confirmed through the experiment using Newton rings that crack opening displacement can be evaluated by employing the white light source and it is shown that there are some advantages in employing the white light source in the optical interferometric technique. Next, a technique to produce a natural crack with various shapes as single edge, quarter-elliptical and semi-elliptical cracks in the heat resisting glass plates is proposed by applying thermal stress which is caused through the repeated heating and cooling processes, and by observing the interferometric fringe pattern. In the single edge crack, the crack growth velocity is about 0.6-32mm/min and this shows that it is very easy to control the crack length. The technique proposed in this study confirmed the possibility of producing the natural cracks with the desired dimensions and shapes in the glass plates.
