An arrangement for mounting a glass member for a field-assisted ion exchange utilizing anodic and cathodic contacting by molten salts characterized by the glass member being arranged between two salt vessels containing the salts, each of the vessels having a contact opening surrounded by a sealing lip or surface for engaging a surface of the member as the member is interposed between the two openings and each of the vessels having an arrangement for evacuation of the vessels to form a seal between the sealing lip and the surface of the member. An embodiment of the invention includes a device for changing the level of the molten salts, either by dipping electrodes therein or by rotating the vessels so that the contact openings may be submerged in the molten salt or be above the liquid salt to allow a removing and changing of the glass members being processed.
An arrangement for holding a glass member for a field-assisted ion exchange with anodic and cathodic contacting by salt melts, said arrangement including two salt melt vessels, each of said salt melt vessels having a contact opening surrounded by a sealing surface, each of said vessels having an electrode engagable with the salt melt in the vessel, means for positioning the glass member between the two vessels with the sealing surfaces of the two vesseIs engaging opposite surfaces of the members, and means for applying a vacuum in each of the vessels to seal the sealing surfaces on the suface of the glass member by suction.
