Eggshell panel "Amanita"

Target: teach how to make a mosaic from eggshells according to plan, and be able to design the work.

Application: The material is designed for children in grade 4, making birthday gifts, decorating the interior of a room, crafts for an exhibition.

Equipment: round board, gouache paints, brush, PVA glue, colorless varnish, gold stained glass outline, toothpick, black marker.

Step-by-step work process

The attractiveness of eggshell mosaic lies in its accessibility: you can achieve excellent results with your own hands, without having any special skills or special devices. You can decorate a variety of objects, decorate any surface

1. I use raw egg shells. For example, I’m preparing an omelette: the contents go into the frying pan, and the shells go into use. Before further use They must be washed thoroughly in cold water, carefully remove the films from the inside and dry.

2. Take a drawing of our future mosaic, printed on a computer. We transfer it to the finished base.

3. The shell is easily glued to PVA. We smear a small area of ​​the design with glue, break it off and lay it down, selecting it by color and shape - as in a regular mosaic.

4. Fill all the empty spaces in the drawing with shells.

5. Lay out the entire pattern with shells.

6. Along the edges of the board we also lay out a pattern of shell pieces.

7. Paint the shell with gouache paints. Using a stained glass gold outline, we draw the tendrils of the spikelets; if desired, we put dots along the edges of the pattern. We outline the entire drawing with a thin black marker. The finished panel must be varnished and your work will sparkle!

* When working with varnish, follow safety precautions. Work in a well-ventilated area.

8. Finished works students in this technique.

9. A product made using this technique will decorate the interior of any home; and the creative process will not cause much difficulty, it will only bring a lot of pleasure! Landscape "In the mountains".

I wish you creative success!

You can learn to make complex, beautiful mosaic paintings yourself. For the first experiments, expensive smalt can be replaced by eggshells; fortunately, there are plenty of colored shells left after Easter.

The shell mosaics were inspired by the paintings of contemporary French impressionist Jean-Marc Janiaczyk. He paints using a palette knife technique. Thanks to a palette knife (artistic tool), paints are applied to the canvas in large, dense, uniform strokes, the color gradations are obvious and clear. Paintings made using the palette knife technique seem to be created in order to be embodied in a mosaic.

Jean-Marc's paintings are full of light, sun, and, no matter what time of year he paints, they always feel a joyful mood. Here are some examples of his works:

Print your favorite image of the painting on a printer in A3 format. When printing, some details of the picture may be cut off. But this can be fixed by stitching the image together.

MATERIALS

• foam board
• eggshells of different colors
• printout of the painting
• felt-tip pens
• PVA glue

TOOLS

• tassel
• toothpick

Step 1

Using a felt-tip pen, highlight the color spots in the drawing. When working with a black and white printout, you will always have to check the color image. Apply glue in several places around the perimeter of the printout with reverse side pattern and stick it onto the foam board with the pattern facing up.

Step 2

The technique for creating a mosaic is extremely simple: select a shell that matches the color of the fragment on the printout. Apply glue to the desired fragment with a size corresponding to the size of the shell.

Step 3

Place a piece of shell on the glue and crush it with your finger.

Step 4

U creative person nothing goes to waste, not even eggshells. There are eggs in every refrigerator, but most people don’t even suspect that you can create a real work of art from their shells. In terms of its hardness, many professionals compare it to marble. Surface chicken egg very difficult to scratch. This is why eggshell mosaics are so highly prized and look amazing. Using eggshells you can create magnificent panels and paintings, do decoupage, create original mosaics and much more. Eggshell is an excellent material for creativity, and we will prove it!

Creating picturesque paintings from broken shells is called crackle. In the East, this technique has been known since ancient times. Today, with its help, you can interestingly transform any object. This creates the effect of a cracked varnish coating.

Decoupage with eggshells

Let's make decoupage using eggshells using this box as an example. Using this principle, you can decoupage any surface with shells.

To do this, we will need items that are difficult to imagine together under any other circumstances: eggshells, paints, a manicure stick, PVA glue, a brush and the cardboard box itself.

There was an old cardboard box, and we decided to give it to her new life! First you need to “sand” the entire box outside and inside with fairly coarse sandpaper, and then go through it again with a “zero” sandpaper.

For decoupage we will need: eggshells, brush, PVA glue, manicure stick

First, apply glue to a small area of ​​the box (we work with small areas, since PVA dries quite quickly). Then we take a small piece of the shell, apply it to the surface and lightly press the stick on the shell so that it cracks, as shown in the photo:

Using the sharp end of a stick, we move the shell fragments apart to the required distance, thus forming a mosaic pattern. The shell fragments, as well as the distance between them, can be large or small at your discretion. After the shells are moved apart to the required distance, they must be pressed to the surface with the flat end of the stick.

Needlework

First, a little about this technique.
Everything is very simple - from eggshells, crushed into small pieces and painted with any paints, you can lay out a mosaic of any complexity.
For example, a very simple one:

Or real pictures:

You can also decorate interior items with such a mosaic:

For those who are interested in this technique - an article from G. Fedotov's book "Encyclopedia of Crafts".

Eggshells are difficult to scratch with a knife and are close to marble in hardness. It is perfectly sanded and polished, acquiring a pleasant soft shine.

In oriental lacquer painting, eggshells were pasted where it was necessary to depict a stone wall or rock covered with cracks. A scattering of small shells imitated the blooming of spring gardens.

The expressiveness of the "crackle" mosaic is given by the so-called craquelures - cracks that form on the surface various materials fancy mesh pattern.

When straightened, the eggshell breaks into many tiny pieces, which do not disintegrate thanks to the thin film located on the inside. Many of the cracks that form between the shells are almost invisible. But as soon as they are developed with the help of some kind of dye, the mesh pattern of cracks becomes visible, turning an ordinary eggshell into an attractive decorative material.

Preparation of material

The collected shells are dipped for two to three minutes in a five percent solution of baking soda, and then thoroughly washed in running water.

The shell is so fragile that it has become a kind of symbol of fragility. When making a mosaic set, the fragility of the eggshell causes a lot of trouble, forcing the master to take special measures and be extremely careful.

But if the shell is coated on both sides with a thin layer of some kind of elastic glue, then it can be cut with scissors. True, the edges of the cut shell will crumble slightly. If you stick thin paper on the shell, you can avoid this trouble. The inner surface of the shell is lubricated with a thin layer of glue, such as PVA (Fig. 1, a).
Then lay out the shells coated with glue on a thin sheet of paper (preferably colored) and press it on top with a flat board (Fig. 1, b). After about a minute, put the board aside and forcefully stroke each shell with a wooden trowel (Fig. 1, c).
The smoother is a rod made of hard wood, the oblique cut of which is polished to a shine. Individual pieces of the shell will split into smaller pieces that will adhere tightly to the paper. After this, a plank is placed on top again and pressed down with a heavy weight (Fig. 1, d). After two or three minutes, when the glue has set, the paper, together with the shell glued to it, is smeared with a thin layer of flour or starch paste. Place tissue paper on the paste-coated surface of the shell and carefully smooth it with your palms (Fig. 1e). A weight is placed on top and the glue is allowed to dry for several hours (Fig. 1, e).

Having glued all the prepared shells in this way, the sheets are put into a folder. In this form they can be stored for a very long time.

On a colored or dark background, the silhouettes of the glued shells are clearly visible even through tissue paper. This makes it possible to correctly navigate when cutting blanks on which the contours of the mosaic elements are drawn. The silhouette of the pasted shell is unique, it can give impetus to the artist’s imagination. You can fit the contours of various animals, human figures, buildings, cars, plants, and much more into it (Fig. 1, g).

Having drawn the contours of a fish found on the shell, for example, they cut the shell with scissors around the silhouette, without trying to work out small details. Using scissors, it is easy to cut the shell along straight and curved lines only from the outside (Fig. 1, h). All kinds of recesses, concave cuts and holes are made with a scalpel or cutter, as well as drills after gluing the shell onto the base-substrate.

Making a mosaic by removing the shell

All work is carried out on separate boards, which act as the basis of the mosaic set - the backing. The prepared shell is cut into polygons with straight sides (Fig. 2, a). At the same time, they try to ensure that they have right angles whenever possible. This will make it easier to fit them to the base sticker. One side of the board is completely covered with shell, carefully adjusting the cut out polygons to each other. Each polygon is pressed as tightly as possible to the base with a smoothing iron. Then they draw on the shell glued to the board with a simple pencil contours of the intended image (Fig. 2, b).

The figure shows the sequence of making a mosaic set with an image of an elephant.
In areas where there should be a background, excess shells are removed with various cutting tools. To drill blind holes, use gimlets or a small drill.

Carving, as well as chipping of the shell, is done with a scalpel or a blunt knife. The engraving is applied with stichels. The work begins with drilling (Fig. 2, c1), then engraving is carried out along pencil lines (Fig. 2, c2), after which they begin to chip away the shell in the areas reserved for the background. Having completed the mechanical processing, remove the tissue paper glued to it from the surface of the shell. First, the paper is carefully moistened with water using a brush (Fig. 2, d1).
After some time, the soaked paper is easily separated from the shell (Fig. 2, d2). Sometimes small seams remain at the joining points, into which small shells are glued.

At the next stage of work on the mosaic set, we begin to identify the craquelures. In this case, the background is painted in some color, for example, black, dark brown, dark blue (Fig. 2, d3). It is convenient to use mascara for these purposes. The mascara contains an alcohol solution of shellac, dyes, glycerin, bile and antiseptics.

Thanks to the presence of bile - a surfactant - mascara easily penetrates into the smallest cracks, carrying with it all other components. Having filled the cracks between the individual shells, the ink not only colors them, but also holds them together. This is facilitated by shellac, which after drying does not dissolve even with water.

After making sure that the mosaic set is painted evenly, use a slightly damp cloth or swab to remove excess ink from the surface of the shell (Fig. 2, e1). After waiting until the remaining ink has completely dried, they begin sanding the mosaic with fine-grained sandpaper mounted on a wooden block (Fig. 2, e).

They sand the surface of the shell very carefully - after all, the eggshell is so thin that in some places it can be easily removed completely. After finishing sanding, replace the sandpaper with regular writing paper. It also has abrasive properties due to the presence of koalin and chalk in it. The polished surface of an eggshell acquires a soft shine and vaguely resembles old ivory or marble. The dark matte background emphasizes and enhances the expressiveness of the mosaic set (Fig. 2, f).

Mosaic set with mastic background

If the background occupies a significant place in the mosaic set, as, for example, in a composition with images of owls, then there is no point in completely covering the surface of the decorated object with the shell (Fig. 3, a). After all, approximately half of the pasted shell will have to be removed later. In this case, it is better to paste over the shell only those areas where the mosaic images will be located directly.

Work on a mosaic set begins with the prepared drawing being transferred to a wooden base.
Then they cut out generalized silhouettes from the shell with scissors and paste them onto the base. After the glue has dried, the excess shell (shaded in our figure) is removed with a scalpel or cutter (Fig. 3, b).

Typically, cutter marks spoil the surface of the background, and in large areas this is very noticeable. However, flaws can be removed by filling the background with a layer of special mastic flush with the glued shell (Fig. 3, c). The most commonly used mastic is epoxy glue filled with graphite, stone dust, and brick powder. You can paint mastic with any dry pigments, as well as oil paints.

The mastic is carefully applied to the background areas with a wooden spatula or a sculpture stack. Once the mastic has completely hardened, the mosaic set is carefully leveled with a file. The mosaic is then wetted clean water. Tissue paper pasted onto the shell gets wet and is easily separated from it. All that remains is to use a brush and ink to reveal the craquelure on the surface of the shell. If the mastic is painted, for example, dark blue, then blue ink is used to develop the craquelure (Fig. 3, d).

Finally, the set is sanded and polished. The entire surface of the mosaic, including the background, acquires an even soft shine.

Mosaic with multicolor background

The background can not only emphasize the beauty and expressiveness of the material used in the mosaic, but also actively participate in the color scheme of the composition. In this case, the parts made from the shell will serve as partitions, separating one section of the background from another (Fig. 4, a).

Mastic of three colors - brown, black and red - is prepared in different jars. First, fill the background areas with brown (Fig. 4, b) and then with dark red mastic (Fig. 4, c). To obtain a speckled background, black mastic is mixed with shells crushed in a mortar (Fig. 4, d).

To prevent the mastic from spreading, edges made of thin cardboard are glued to the edges of the board with the mosaic set. After the mastic has hardened, the sides are removed, the mosaic set is carefully leveled with a file and the remaining tissue paper is removed. The shell is covered with black ink. As soon as it penetrates deep enough into the cracks of the shell, its excess is removed with a slightly damp cloth. After a few minutes the ink has dried and the set is sanded with fine-grit sandpaper mounted on a wooden block and then polished. The black speckled background of the mosaic will appear to be made from many individual shells.

If it was possible to prepare a shell that has various natural color shades, then, if possible, they use this modest palette, for example, when working on a mosaic panel based on ancient architecture (Fig. 5). Let's say the master has white, brown and cream shells at his disposal. White shell is suitable for simulating snow, white stone walls, brown for fortress walls and towers, and cream for buildings located inside the fortress. This is, of course, an approximate layout.

The use of a particular shade of shell will depend on the nature of the image and the task facing the artist.

Mosaic on turning products

Completed on lathe Wood products can be successfully decorated with eggshell mosaics (Fig. 6). When turning on workpieces, small recesses of no more than 0.5 mm are selected in advance with a cutter. The mosaic elements are glued onto the surface to be decorated and carefully rubbed onto it with a smoothing iron (Fig. 6, a). Then the product with the mosaic set glued to it is tightly wrapped with some kind of harness (belt or rope), tightly laying the coil to the coil (Fig. 6, b). To prevent the glue protruding from under the shell from sticking to the bundle, the product is wrapped in newsprint in advance. After the glue has completely dried, the rope is removed, and the areas where the shell is not glued are filled with epoxy mastic (Fig. 6, c).

When the mastic has hardened, begin sanding the mosaic set. You can grind directly on a lathe, taking the necessary precautions, or manually, attaching sandpaper to a wooden block with a grooved recess corresponding to the diameter of the workpiece (Fig. 6, d). After identifying the craquelure on the shell and subsequent polishing, the wooden parts of the product are painted dark with stain.

Finally, the entire product is rubbed with wax mastic or varnished and polished.
