Varieties and scope of fish glue, how to make it yourself

Fish glue is a binder made from swim bladders. For this substance, valuable and massive species of fish are used. Additionally, glue can be made from waste from the fishing industry. In order for the use of the substance to bring the required results, it is necessary to strictly follow the instructions and ensure the correct preparation of the surfaces.

General description and characteristics

One of the best and most effective ways to fix different surfaces is fish glue. It is obtained from the swim bladders of fish. Most often, representatives of the Sturgeon family are used for this. These include star sturgeon, beluga, sturgeon. It is also possible to use other fish - especially catfish.

Fish glue comes in the form of large slabs, fibers or shavings. They can vary in thickness. It is better to use natural glue in the form of plates. These are fragments of the walls of the swim bladders. An inferior composition is made from bone fish scales. It is a thin plate of hard consistency that can have different shapes. Additionally, glue is often brewed from heads and other waste from the fishing industry.The properties of the substance are due to the presence of collagen in the composition of these products.

In some cases, fish glue is obtained from broth, which is prepared by melting fat with the addition of water. In this case, after removing the solid residue, a thick broth accumulates in the container. A small amount of alum is added to it for purification and poured into molds. Once the jelly has solidified, it is cut into tiles and dried.

This type of glue can not be considered very popular. However, there are several production areas in which it is actively used. These include in particular the following:

1. Winemaking. With the help of glue, impurities and sediments are absorbed into the viticultural material. Thanks to this, they can be quickly removed.
2. Restoration. Fish glue is used as a base for paints and artistic primers. It is used when restoring old canvases. Also, the substance is used for the restoration of furniture, mosaics and frescoes.
3. Make musical instruments. In this case, only high-quality and expensive types of glue are used. This is due to the specifics of production.
4. Light industry. Fish glue is often used to decorate clothing.
5. Manufacture of furniture and carpentry. The substance is used for the manufacture of mass products.

The advantages of fish glue are:

• lack of smell and taste;
• moisture resistance;
• lack of color;
• excellent mechanical binding parameters.

At the same time, the glue also has a number of disadvantages:

• lack of heat resistance - the maximum allowable heating temperature is considered to be 80 degrees; at higher settings, the composition begins to break down;
• high price;
• the risk of destruction under the influence of mold, parasites, pathogenic bacteria.

Varieties of fish glue and their purpose

There are a number of varieties of isinglass, each with specific characteristics.

Sturgeon

This substance is also called dwarf. It is made from the swim bladders of representatives of sturgeon breeds. Such glue is produced in the form of dry plates with a translucent texture. They are small in size and weight. They are usually sold in sets of several. These items weigh 50 grams. If the karluk is made to order, then it can have arbitrary dimensions and weight. These parameters are determined by the buyer. At the industrial level, the production of such glue is carried out in countries where there are representatives of sturgeon breeds. It is made in Russia, America, Iran.

Usual

This glue is made from large species of fish. For this, bone cartilage tissue and skin are used. The substance is sold in the form of dry granules or thick formulations with a viscous consistency. At a cost, such glue is significantly lower than sturgeon, but much more expensive than carpentry. The price difference is due to the composition of the adhesives. For the preparation of sturgeon substance, the cartilage and swim bladders of large fish are used as raw materials with the help of fins and skin. To make wood glue, take any scraps left over after cutting.

Carpenter

This type of fish glue is considered the most common.For this, all residues from the processing of materials from the fishing industry are used. The fins, heads, scales and entrails of fish serve as the basis.

How to do it yourself

If you cannot get ready-made glue, it is permissible to make it yourself. Manufacturing technology is affordable and simple. In this case, the process of cooking the adhesive composition is considered quite long. Experts advise boiling fish glue if you have the necessary materials to make a composition of a particular variety and quality. Depending on this, it will be possible to get carluk, ordinary or carpentry glue.

Before starting the manufacture of such a substance, it is worth making sure that there is no allergy to the specific smell of fish.

The easiest way to make carpentry fish glue. This is due to the availability of raw materials. Dry records can be found and purchased if needed. Thus, in order to obtain an effective composition, it is recommended to proceed as follows:

1. Grind the plates. This should be done to the size of gelatinous granules.
2. Place the raw materials in a suitable container and cover with cold water.
3. Let stand 5 to 6 hours in a warm place to swell the material.
4. Grind the finished mass with your hands. As a result, it is recommended to obtain a porridge consistency.
5. Place the dish with the solution in a water bath.
6. Stir constantly to obtain absolute dissolution. It is important to ensure that the mixture does not heat up to a temperature above 80 degrees.
7. Add an antiseptic to the adhesive. This will help prevent putrefaction in the composition.
8. Strain through cheesecloth.
9. Pour into a molding container.In this case, it is recommended to place plastic wrap on the bottom and sides.

After that, glue can be used. It is recommended to dry the remaining product and store it in an airtight container. This will allow it to be used as needed.

Application Tips

The use of fish glue differs depending on the type of surface and other factors. Experts do not recommend storing the finished composition for a long time. This will lead to the solidification of the mass and the loss of its properties. Before using the glue, it is worth preparing the surfaces for gluing. This rule cannot be neglected, since the mass best retains its characteristics for 2 hours.

If there is a need for an adhesive composition, it is allowed to introduce additional additives that will improve its characteristics. Fish glue is considered an effective product that helps to achieve a strong and secure hold. To achieve a good result after using the substance, you should pay attention to the choice of composition and strictly follow the instructions for use.
