A glass capillary tube (ID 1.5 mmφ× OD 8 mmφ) is used as a cell of the library. Zinc tellurite melt at 800 ^∘C is sucked into the cell by applying a vacuum pressure to the other side of the capillary. Crystallization is observed as a white segment in the library under an appropriate annealing condition. A set of 2D sample array is obtained by preparing several sample libraries with different annealing time. Since this array itself corresponds to a T-T-T (Time-Temperature-Transform) diagram, a tangent which touches the crystallized region and pass through the melting temperature at t=0 gives critical cooling rate, Q. Compositional dependence of Q shows that the minimum of Q is not located at the eutectic point of ZnO-TeO2 system, which has been believed to be most stable composition on the basis of the known glass forming regions, but is shifted to ZnO-rich region. Considering the high reproducibility of this automated system and the large error bar of previous results, this result is more reliable. We also investigated the dependency of Q on thermal hysteresis. For the melt once quenched below the glass transition temperature (T\mathrmg) and annealed at above T\mathrmg, the Q value becomes larger than that without the quenching. This is because the former glass melt went through the nucleating temperature region located just above T\mathrmg. It is concluded that this automated system makes it easier than ever to examine quantitatively the thermal stability of glass melt having low melting temperature, which is one of the important factors for judging the feasibility of fabricating new glass devises with desired quality."

This method reduces the laborious routine work for preparation, which is needed in the conventional method. Since the surface/volume ratio of the present samples is large, their crystallization is mainly governed by heterogeneous nucleation. Thus, the Q values in this study can be used as a practical index for the glass products whose surface should be free of being ground and/or polished, such as fire-polished lenses, optical fibers and waveguides.
