2. Solder will not stick to glass alone, therefore each piece of glass must be wrapped in copper foil or lead came. Copper foil is a technique, made popular by L.C. Tiffany at the turn of the century, involves wrapping the pieces of glass with copper foil and soldering them together along the length of the seams. 

3. Never use acid or rosin core solder for stained glass, only use solid-core solder. 

4. Solder needs a flux to flow smoothly and bond to other metals like copper or lead came. 


5. To use solder you must use a soldering iron that melts the solder to liquid state (approximately 700°F).

6. Handling solder poses a risk of lead poisoning if certain safety precautions are not followed lead cannot be absorbed through the skins – only through ingestion or an open cuts. Make sure to always wash your hands well and always bandage any open cuts on hands and fingers. Always be careful!
