School glue is often white and other forms of glue can be black, brown or some other color. Those who want to create clear glue will must add alum. Glue is not clear because it contains impurities, which must be removed to make the glue clear. Nevertheless, resin, made from many items in the woods, can be combined with household chemicals to create glue that dries clear and holds strong.

Get pitch. Pitch is a sap that pine trees release when the bark is injured, to prevent insects and microorganisms from entering the tree.
Grind charcoal and plant material into a powder using a grinding stone.
Put the pitch in a pot and cook it until it melts.
Stir 10 parts melted pitch into two parts powdered charcoal and two parts ground plant material. The material will turn thick and black, stiffening very quickly. While it’s still warm, it can be formed into a ball.
Remove all the dirt from the materials you will use to make the glue, so they contain a minimum number of impurities, which can make the glue less clear.
Mix 1 cup of flour and 1/4 cup of resin glue together in a saucepan. Add one cup of warm water to the paste. Mix the warm water with the wheat flour.
Add 3 cups of hot water. Stir the mixture so no clumps form.
Place the pot on a stove at low heat. Keep stirring until the glue becomes thick and clear.
Add 1 tablespoon of alum to the mixture. The impurities in glue, which makes it unclear, can be removed using alum. These chemicals cause the impurities to settle to the bottom of the pan. This type of glue will dry clear and harden more than most forms of glue. Wait until the glue cools and then remove it from pan, putting it in a jar.
