Title:The glazing of a stained glass window in the Bryn Athyn glass factory

Medium:35mm slide
Description: The job of the “glazier” was to assemble the various elements of a stained glass window using pieces of lead. The final step was to insert putty beneath the lead to seal the window and make it waterproof. “Now, if we were to put it into the window with just the joints soldered, of course, it wouldn’t be waterproof, and it wouldn’t be windproof. So he first solders it on one side, then turns it over and solders it on the other side, and then he, with this knife, he gently lifts up the flanges of the lead. We then make a cement, the basis of which is putty, but it has other elements in it, and this is actually poured onto the glass, and scrubbed in with a scrubbing brush, so that all the surfaces between the lead itself and the glass is thoroughly filled with this material” (Gunther, Ariel.
