Glass defects

This book is the first closed representation of errors in optical glasses. It combines research with practical experience in the production of optical glasses. The rich pictorial material reflects the intense experience of the author. "Glass defects" is aimed at researchers and practitioners in glass development and production. Due to the many components of optical glass, unusual phenomena occur which are also of general interest to mineralogists and materials scientists. 14 years the author was in production at JenaerGlas Schott und Gen. From the content: crystallization phenomena as glass defects - small stones, knees and inclusions - streaks in optical glasses - gases in optical and technical glasses - micro-transformation - surface defects.
