I simply must add my two cents worth on terminology used. First for the novice lets define Stretch. A glass article is made, doesn't matter how, and while hot it is sprayed with metallic salts, it is then reheated and in the reheating the glass expands at a greater rate than where the salts were applied. Further working of the piece increases the effect. Thus you have a stretch effect. The stretch effect can be found on pressed molded wares as well as Tiffany, Steuben and even into the present day with modern artists like Steve Lunberg. So the statement that all stretch is pressed and moulded to me is the same as stating that all irrid. glass is carnival. Stretch is an effect and if I were to describe your bowl I would say " Art glass bowl, polished pontil with stretch effect." Terry
