When the glue absorbs all the water, it will turn into a gelatinous mass. Then it will be necessary to pour hot water into the outer dish of the gluten, then put it on a small fire.

You can also make dextrin from starch. To do this, put the starch in an enamel or porcelain dish, and then place it in the oven. The temperature in the oven will need to be gradually raised to 160 ° C. Upon reaching this temperature mark, the glue should be kept at it for 1.5 hours.So in the process of temperature splitting the starch will acquire a yellowish color. In this state, it will turn into dextrin.
This type of glue perfectly glues wood, cardboard, paper, leather. And while he is almost not afraid of moisture. Casein glue is also easy to prepare.

After that, it is cut into small pieces, put in a vial with a ground in stopper and pour in acetone. It should be noted that the amount of acetone should be twice the volume of the film. After that, the vial should be tightly closed, and let it stand until the film dissolves. All this time, the vial should be periodically shaken. Now the glue is ready. According to its density, it should look like liquid sour cream.
Many are interested in how to make glue with their own hands, which will not be afraid of moisture. And you can cook it from freshly coagulated milk or cottage cheese. It must be mixed with slaked lime so that a homogeneous thick mass is obtained. The resulting texture should be applied to the glued wooden surfaces in a uniform, thin layer. After which they should be strongly compressed and dried.
