I'm working on restoring windows in a former mining worker's house in Michigan's Upper Peninsula. This modest worker's house was built around 1895 and most of the windows are in need of freedom from a hundred years of paint. I started work on one already, and found that the wood is in good shape and these windows are worth saving. However, I'm finding very little information on how to restore this type of window. The upper sash is fixed and lower sash raises. The panes of glass are secured not by glazing putty, but by muntins or glazing bars (took me forever to learn this much!). There is one pane of glass cracked in the first window, and I've removed the glazing bars and scraped away a very thin layer of residue. As I put a new pane in, should I secure it with anything other than the glazing bars (a.k.a., muntins, mitered molding)? Like a very thin bead of caulk or putty? Or should I just tap the brads back into place and paint over with the linseed oil paint I'm using to repaint with? In general, are there any resources that describe this type of window and how to care for them? Thanks!
