Lifting Foil

My foil is lifting after I solder, I have burnished very well, where the foil meets the glass is so smooth and it still lifts????I'm getting very frustrated.

Answer

You need to make sure the glass is absolutely clean before you apply the foil. After you cut and grind, wipe the edges with alcohol before you foil. The alcohol will clean the edges and it seems to make the foil stick better.

Also, if you read through the copper foil questions page you will find many questions (and answers) about the same or similar problems. There should be other answers that will help.
