Abstract: A stacking and storage container for metal chucks used in machining optic lens comprising a housing formed with a top and bottom surface interconnected with a plurality of tubes with openings into the tubes through the top and bottom. The top, bottom and tubes are constructed of a material such as plastic that does not transfer heat or cold. Slides are positioned along opposing sides of the bottom for receiving a plate for covering the bottom opening of the tubes when positioned along the slides covering the bottom surface. The slides and bottom plate are constructed of a heat and cold conducting material such as metal. The chucks when placed within the tubes with the bottom plate installed covering the bottom openings of the tubes are cooled by placing the container on a cold surface or in a refrigerator whereby the cold is transferred through the plate and slides to the chucks therein. The cold chucks are removed for use by sliding the plate from bottom of the tubes.
