Foiling is a very important part of making a stained glass window. Often I see students rush through the foiling process without regard to how it looks because they feel the lead will cover it. This is truer than you might believe. Lead follows your foil perfectly. Any flaws that you have in your foil show up in the lead as well.
Below we have a picture with two large problem areas. The red arrow points to a stair-step which happens when the starting and ending points of your foil don't line up correctly. Any lead that you apply on top of the stair-step will take the same shape. It won't hide the problem. Next, the green arrow points to a section of foil that has been flipped upside down so that the adhesive side is upward rather than against the glass. I've used black backed foil so you can easily see that the black back side of the foil is facing upward. This often happens in corners if you aren't careful enough to tuck one side of the foil under the next side as you would wrap a Christmas present.
Here's how to fix these problems. First off we need a SHARP razor knife or Exacto knife to trim off that offensive stair-step. To do that we start at the large overhanging area by butting the blade against the foil we want to match and then traveling downward along the dotted line I've added to the picture. Once the stair-step is removed you can simply use your fingernail in the upper right of the piece to flip the small area of tape so the back side is facing downward. If you can see the adhesive side of the foil no lead will cover it.
Remember, solder will not hide bad foiling but instead highlight any and all of your problem areas. Your soldering will only ever be as good as your foiling so foil carefully.
So first off we look at Lara's Caduceus Window which was completed in just 2 weeks from start to finish. Now we did rush a bit on this but in the end you can't tell at all because Lara's attention to detail outweighed Lara's need for speed. When she asked what color would work well as an accent border with all of that white in the center I knew instantly that blue was the answer-- especially when she said that the window was being made for a man. Perfection.
Now this is what Lisa's four frogs looked like when she left class last week. She had managed to get them all cut and ground (all at once) and then took them home to wrap in foil. This week we saw her solder them all and attach them to their nightlight bases. Showing you this picture in this postafter you've already seen them completed is my way of saying 'Better late than never.' Right?
Cindy finished cutting and grinding her Nicholl's Logo Panel and at this point I'm unsure if she's going to add a border to surround this or not. I guess it all depends on how large she wants it to be. Normally I say a border is necessary mainly for hanging purposes but the N creates lead lines at nice even intervals where we can attach hooks if Cindy chooses to forgo a border.
