Bottle Bricks and How to Make ’em
You can make bottle bricks by simply placing two bottles together and taping them. Or you can cut each bottle and tape them together. Here are pictures showing how to make bottle bricks. In this case, a picture truly is worth a thousand words. The finished bottle ends are being pricked with a map pin to allow moisture to transpire. (Editor’s note: If your bottles are completely dry there is no need to make a pin hole.)
Dozens of bottle ends are ready to provide a spot of light in the wall. We have found that that aluminum flashing needs to go to within an inch or two of the end on each side for maximum light transfer.
How did we make all of these bottle bricks? It is important to start collecting a large number of bottles and vases ahead of time. The glass must be clean and dry. It helps if the labels are removed.
There needs to be an ample amount of clear and colored glass to brighten your walls.
Sometimes even paws and a wet nose are helpful to sort and select bottle sizes.

Below are a set of pictures showing how to put two bottles together “WITHOUT” cutting.
Note that the neck of one bottle is accepted by the opening in the other. This is especially useful when using bottles with different diameters. (Oval, diamond, rectangle, etc.)

It is good to have extra hands.
Objects can be placed inside bottles. These are being used at the Cordwood Education Center, which is a cordwood public school classroom. Aluminium flashing and tape were added to these before placement in the wall.
