Midpull

Midpull refers to a specific phase in the process of drawing glass, particularly in the context of glassblowing or other hot glass shaping techniques. It occurs after the initial gathering of molten glass from the furnace and before the final shaping or cooling stages. During the midpull, the glassworker manipulates the semi-molten glass, often by rolling it on a marver, swinging it, or using tools, to refine its shape, equalize its temperature, or prepare it for further manipulation. This stage is critical for achieving symmetry, control, and the desired form of the glass object. The duration and specific actions taken during the midpull can vary significantly depending on the complexity of the piece being created and the desired outcome. It is a period where the glass is still pliable enough to be worked but has begun to cool and solidify to a degree that allows for more precise control. Successful execution of the midpull ensures that the glass maintains its integrity and moves towards its final intended shape without distortion or flaws.
