• Air Twist - An air twist is a decorative feature found on some types of glassware, including Georgian drinking glasses. It is created by twisting the glass while it is being blown, which creates a spiral pattern of ridges or rings around the stem of the glass. The air twist is typically made by a skilled glassblower using a hot glass rod to shape the glass. It is a decorative feature that adds visual interest to the glass. Georgian glassware is known for its high quality and intricate design, and the air twist is just one of the many decorative elements that may be found on Georgian drinking glasses.
• Twist - A rod of glass in which there is one or several threads or tapes of coloured glass, or bubbles of air embedded, which is then twisted to give an attractive appearance. The technique is mostly associated with the stems of Georgian glasses. The technique was in use from about the 1740s to the 1760s.
  
  Collectors have identified over 150 variations of twist decoration. One of the most common is the air twist which as the name implies, has one or more columns of air embedded within the rod. A colour twist has one or more coloured tapes, usually opaque but sometimes translucent. other common types of twist include cable, corkscrew, enamel, gauze, lace, opaque and thread.
• Bowl - With drinking glasses, the bowl is the hollow section of the glass that holds the liquid. Many glasses were mounted on a stem joined to a foot, others were cylindrical, of tumbler shape. The size and shape of the bowl was determined by the type of liquids they were meant to hold. Shapes used included bell shaped, conical (funnel), bucket shaped, trumpet, cup, ogee, funnel, cylindrical and rounded.
