Glue made from starch - paste - has long been used for gluing paper, cardboard, as wallpaper glue. And although there are a lot of different ready-made adhesives in stores, paste is still very popular today. Making glue from starch is quite simple, you just need to adhere to simple rules.
It is necessary
- - starch;
- - cold water;
- - boiling water;
- - container for the preparation of glue.
Instructions
Step 1
Measure out the required amount of starch. Pour room temperature water into it. Stir the mixture, breaking the lumps thoroughly. Starch does not dissolve in water, you should get a homogeneous suspension of starch particles in water - a starch suspension.
Step 2
Pour boiling water into the prepared starch mass, stirring continuously in one direction, twisting the mass with a funnel so that no lumps form. Watch the mixture's thickness - the finished paste should have the consistency of a thick jelly and be transparent. Note that the paste will thicken as it cools.
You can, on the contrary, pour the starch mixed in water into boiling water, stirring the mass intensively. The starch should brew well. It is better if the mass is on low heat. Stir the glue to prevent it from sticking to the bottom of the cookware.
Step 3
Cool the finished paste to room temperature. During the cooling process, stir the mass of glue periodically so that a dense film does not form on the surface. Strain the cooled paste through a sieve, gauze or nylon stocking to separate possible lumps.
