Pictured at right  and below  is of some of the hardware from the doors of First Church Christ of Scientist. The size and weight of these doors required hinges with bearings. The bottom row of photos show the parts of one of these bearings. The bearing pictured was dis- assembled for repair and lubrication. The stripped and polished hardware was painted with bronzing powder in lacquer and then a coat of clear lacquer was applied. The final step was the application of a burnt umber glaze.
