Welcome to the website. The goal of this site is to list every known vintage refiner from A-Z and compile any information possible about these companies. On mobile, click on the sidebar link at the top to see the alphabetical table of contents from A to Z.

Have a silver bar you have questions about? Either or I would be happy to provide any information we know about it if we can.

If you are looking for Engelhard information, please see All Engelhard. Their knowledge is massive. They also have a 'Other Refiners' page that has a good selection of other refiners such as Johnson Matthey, etc.
