Elementary AdhesivesThere are a number of simple ways to make glues using various starches, flour, or gelatin. An improvement to these formulations is casein glue. While it requires a little effort to make, it is still not difficult and it is a superior product. In fact, it is related to some of the famous brands available at your store, including construction glue.
Milk is a NaturalCasein is an important phosphoprotein found in cow’s milk. It has been used for hundreds of years on porous materials such as paper and wood. To make this historic glue, you will need a quart of skim milk, two cups distilled (white) vinegar, a steel saucepan, a medium glass bowl, a coffee filter, a mixing spoon, an 8-ounce glass, and four teaspoons of baking soda (sodium bicarbonate).
The French ChefFirst, in a saucepan, combine the milk with the vinegar. Place the saucepan on the stove and heat it at a moderate temperature. After the milk is thoroughly curdled, take it off the heat; allow the solids to settle. After cooling, use the coffee filter to separate the solids from the liquid. Discard the liquid.
Squeeze the excess moisture from the curds and press them with a paper towel. Now transfer the curds to the glass bowl.
Fill the glass about three-fourths full with hot (not boiling) water; dissolve the baking soda in the water. Now pour half that solution into the bowl containing the curds. Stir and let the mixture set with occasional additional stirring until the mixture completely dissolves and is uniform. Add additional baking soda solution, as needed. Do not add too much, as you do not want the glue to be too thin and runny.
The Result? High Quality Casein GlueYour yield should be approximately one cup of glue, plus a good deal of pride. It should be comparable to any quality commercial product.
