Why are the bottoms of bottles hollow?
This characteristic is very old and actually dates back all the way from the 4th century. During this time is when we first see this distinctive hollowed style on the punt, i.e., the bottom of a bottle. The primary purpose of this hollowed punt is to ensure the stability of the bottle when it is placed upright. Why not just make it flat? Fifteen centuries ago, craftsmen were unable to make bottles with a perfectly flat punt, which caused some difficulty in standing them upright. Craftsmen decided to solve the problem by stabilizing them with a heavier concave base. See acast.com/privacy for privacy and opt-out information. Hosted on Acast.
