A pattern set is when the design flows from one window to the next. Please Read This Carefully. We only sell OLD Windows. Glass making was not perfected until around 1930. Before then a lot of glass, especially glass made in to sheets had bubbles, waves, imperfections such as ridges or lines of separation when the glass was made. It’s not unusual at all to find these in our windows, in most cases it’s desirable because it validates the age of the windows. If you get a window that to you looks like a “crack” is in it, simply run your finger across the line on both sides to “feel” the glass, if one side is smooth and the other side has a ridge or bump, it’s simply an imperfection in the way the glass was made. CRACKS Can Be Felt On BOTH Sides of the Glass, you can’t crack one side on a piece of glass without cracking both sides. Each of these windows have three (3) types of Green, Red, Two (2) Types of Amber and a type of textured white. There are No Cracks in the glass of these windows. The overall size of each window is about 21 3/8″ wide by 18 1/2″ tall. The glass size in each window is about 17 3/8″ X 14 3/8″. Check Out My Feedbacks!!
