Differential thermal analysis was applied to detect some characteristics of glass under transformation temperature range.<BR>At first, the apparatus construction of sample holder parts and measuring conditions were investigated, and then checked with some glass samples. The author found fairly good analytical conditions for detecting some characteristics of glass during the transformation range. These are as follows: 10°C/min heating rate, 200 mesh sample grain size with Pt-alloy sample cell in the symmetrical hole type ceramic block.<BR>The method was applied to commercial glasses. Analysis of D. T. A. curves of some glass samples had been tried by comparison with other characteristics of transition range, got by the methods of dilatometry and viscosity measurements.
