A great reference for you would be works by Alexis G. Pincus who very thoroughly documents the use of molds in the glassmaking industry as well as decorating in the glass industry. Specific titles are Forming in the Glass Industry (Ashlee Publishing Co, 1983) and Decorating in the Glass Industry (Ashlee, 1984). According to Drinking Vessels of Bygone Years (1927) by G. J. Monson-Fitzjohn, mugs were commonly made of wood and bone, and eventually were made of clay. It was in the 2000 BC that mugs made of metal began to be produced. Another source that maybe be of interest to you is our resource guide on Drinking Vessels Through History, which includes information on how various drinking objects were made and shows some videos of techniques of creating stems, decorations, and handles.
