The strongest glue based on resin and charcoal with your own hands. So, in life there are situations when you really need strong glue, for example, for the house, repairing equipment, creating birch bark dishes with your own hands or feathering the arrows of a bow. There are many ways to get glue in the natural conditions of real nature, but if you are in an area where there are many conifers that still have "evergreen", then you are terribly lucky.
An easy-to-manufacture and very strong adhesive can be made using coniferous resin and additional components.
One of the features of conifers is that they are able to heal their own "wounds" with resin or sticky juice.
When you travel through the forest, from time to time you will notice lumps of such a substance on tree trunks. Insects and various debris often freeze in the sticky mass. In addition to a physical barrier that helps stop pests from entering damaged areas of the tree, resin has certain compounds that will prevent microscopic organisms from multiplying. A similar property of the resin can be used to treat wounds on the human body or to impart antiseptic properties to handmade soap (lye made from wood ash as fat).
You will need:
It is possible to collect the resin, that is, the first and most important component can be obtained from different conifers, but please note that the resin from different trees has a different consistency and unique properties, therefore it will be necessary for an experienced by achieving the optimal formula for preparing the glue from the ingredients. Charcoal is widely used for extreme situations and survival.
It can be used to camouflage objects, camouflage, purify water, for medicinal purposes, and to create glue. Pieces of dried coal (a product of incomplete combustion of wood) can easily be found in the remains of a cooled fire.
The glue will actually be more effective if there is a binder in it. Vegetable fibrous material is ideal for this, but keep in mind that it should be fine. Cannot be excluded from the lists of components for use and the results of waste from herbivores.
Instead of using time and energy to collect and chop leaves and dry grass, you can let the animals (deer, elk, and rabbits) do the work for you. Such animals are herbivores, that is, they feed on plants, and usually do not eat meat at all.
Plant buds, leaves and grass are all things that are poorly digested, so herbivores must break them down and grind them so that the stomach is lightened to the maximum. In both humans and herbivores, the concentration of hydrochloric acid in the stomach is 10 times weaker than in predators, so the digestive process will begin in the mouth, with the help of a special enzyme called ptyalin, which helps in the breakdown of starch and polysaccharides, which are very abundant in plant foods.
Use a flat base stone and a rounded stone to grind charcoal and plant material to grind ingredients and create a resin, herbal, and charcoal glue.
It may take a little more effort and time, but if you can crush everything to a powder state, then everything is fine. Next, you should melt the resin. It is better to use a Dakota hearth for this, and it will be the best solution to the problem, as it creates more heat, it is easier to control, and it will emit less smoke with a small amount of wood.
In addition to everything else, the Dakota hearth causes minimal damage to the environment, and this is an extremely advantageous position. You must be careful while heating the resin as it is flammable.
So, if the flame is near the molten resin composition, the fumes can pick up the fire and you will have to put out the fire. For this reason, it is better to melt the resin on hot coals, which will reduce the risk of ignition of the heated substance in the heating vessel. When everything is melted, the ingredients should be thoroughly mixed, namely, the charcoal and plant fibers should be added.
The approximate ratio is:
Once everything has been mixed, the glue will become thick, black, tar-like and very sticky. You will see that the gummy mass will begin to solidify quickly when removed from the heat source and soften again after being exposed to heat.
It is not difficult to use glue, for this you need to roll it into a ball while it is malleable and warm, and if necessary, warm up small areas and process the surfaces that you plan to glue. For best results, only heat surfaces before using the adhesive so that it does not harden too quickly.
There are alternative recipes that can be used to make glue, and this includes different combinations and ratios of charcoal, resin, plant materials, iron filings, sulfur, fur or hair , animal fats or beeswax. Depending on what components and preferences you have, materials can be used to make good, strong home glue.The main component will still be coniferous resin, but recipes can be improved if you use the rich resources of nature.
There are big differences between glue and resin, which will reveal imperfections that are unacceptable:
In addition, epoxy glue can be made from resin. For the first time such a resin was obtained by a chemist from France Castan.
Currently, epoxy can be obtained from a variety of epichlorohydrin compounds and organic compounds. This is called "epoxidation". Valuable epoxy-type resins can be obtained by catalytic oxidation of the unsaturated compound. For example, this is how cycloaliphatic resins are obtained, which are valuable in that they do not contain hydroxyl groups, and therefore they have resistance to water, which has a positive effect when using material for the house.
For the practical use of resins, a hardener is required.
It can be an anhydride or polyfunctional amine, other acids. You can also use catalysts for hardening. After mixing with it, the epoxy will quickly begin to harden and become insoluble and infusible. If you use PEPA, the resin will be able to harden in 24 hours at room temperature, and anhydride-type hardeners will require 10 hours and warming up to 180 degrees in a special thermal chamber.
