"Star" type cuts on the underside of feet are too often overlooked. It is important to look at the mitre cuts themselves as they are a source of dating evidence.
On some early examples the opposing face of each cut often differ in length and width. These were made with two cuts. We have seen this tell ale indicator on a marriage glass dated as late as 1807.
On this example the mitre is uniform, however the polishing within the cut is not. As the cut narrows the polishing within the cut is progressively less effective and negligible in the base of the cut at the narrowest points. We have examined various glasses with "star" undercut feet from the early 19th century to the early 20th century. This "issue" with polishing mitre cuts had been solved by 1850-60. This was due to two factors. Firstly the ready availability of constant power with reliable delivery or torque at cutting wheels. Secondly the cutting tools and polishing tools and methods themselves.
A customer with a fifty year career in glass cutting who finished his professional career with Tudor crystal is writing an article on this very subject for us with a focus on "telltales" and production method.
