This item was used at a local ophthalmologist's office. There are small dot-like marks where a pestle made contact with the surface. It fluoresces under a black light. The image taken with a 395nm wavelength was captured with a high-sensitivity digital camera, so it appears slightly fainter to the naked eye. There is a chip on the rim, which has been carefully repaired with a hard, transparent resin. Diameter: 6.8 cm Height: 4.4 cm For those interested in old glassware and who can accept the scratches and stains, thank you for your consideration.
