They were likely given the name "dump glass" as the glass used to make them would otherwise have been dumped at the end of the day. Smaller examples of dump glass weights were used as paperweights, and larger ones as doorstops. Many weights had internal designs; controlled bubbles, complicated designs made from foil or powder, and rarely sulphide plaques or figures.
The vast majority of these objects are unmarked and have a rough pontil base, but there are some examples that have been given a factory stamp on the base. This example is on the larger side, 5" tall and 3.4" in diameter, and was probably used as a doorstop. The interior design consists of a pot with two flowers, and was done using the powder technique.
The base has a rough pontil mark. As is the case with the vast majority of dump glass weights, there are some minor inclusions and bubbles in the glass.The surface of the weight has some minor surface scratching and three small (1/4 or less) bulls-eyes, also common for weights of this size and age.
