Repairing and Replacing Old Lead in Stained Glass Windows

Hi,
I have been given two semi circle stained glass windows, the lead is old as the windows themselves are.
I'm concerned these do have dangerous lead content in them. How can I safely replace the old lead?

Thank you,
Sophie

Hi Sophie,

Lead is lead, old or new. However, the old lead may have started to flake, so wear a dust mask and gloves to remove it. In addition, wear the same gear when removing the old putty. There could be dust flying around when you remove it. Vacuum often to keep the dust under control and don't do the job where dust would be near children or get into food. Common sense is the main factor here.
