Abstract
A method of making rings which includes the steps of placing tubes into a container, filling the container with a bonding material in liquid form, solidifying the bonding material within the container, slicing the container into wafers and then removing the bonding material from the wafers leaving the rings as a residual product. The wafers can also be metalized in order to metalize the upper and lower faces of the rings embedded therein.
