To make metal leaves of plants, prints on wax composition are taken from fresh leaves as follows. A wax composition is poured into a mold made of thick paper, allowing it to cool down approximately to full curing, but in such a way that its surface is elastic. Then on the surface of the wax impose leaves also press them with glass. When the glass is also removed, the leaves leave a clear imprint on the wax composition.
After the wax has hardened, the imprinted form is gently graphitized with a soft brush. Having installed the conductors on the form, hang up the load and lower it into the electroplating bath.

To cover insects with metal (butterflies, beetles, etc.), they are prepared in an appropriate way: insects are kept in a 1.5% solution of mercuric chloride, dried, coated with varnish or a thin layer of wax. Then the surface needs to be made conductive, for this it is brushed with a brush of graphite diluted in alcohol or Vodyar with a brush. After drying, excess graphite is removed.

Plant metallization technology is also insects.

After this, the object is suspended on several thin copper wires with a diameter of 0.1-0.2 mm, twisting or tying them repeatedly crosswise (Fig. 1), is also placed in a galvanoplastic bath. To eliminate buoyancy in electrolyte, a butterfly, a bug, etc., is attached with paraffin to glass or a piece of plastic. The metal is about to be deposited preliminarily around copper wires, spreading very slowly over the rest of the surface. Therefore, in the source of the process, the current is forced to be several times less than normal, at which time the entire surface will be "tightened" by the metal, bringing it up to the norm. The duration of the process is several hours. Coating thickness can vary from 0.1 up to 2 mm.

Using the electroforming method, metal can be used to decorate lace for decorative and artistic decoration of various objects.

Lace stretch on the frame is also impregnated with paraffin. They are then ironed between sheets of paper to remove excess paraffin. Next, a conductive layer of fine graphite is applied, the excess is carefully blown off the laces. Laying the conductors on the outskirts of the lace, they are attached to a plastic frame or a frame of thick wire with vinyl chloride insulation, together with which the lace is immersed in the electrolyte.

Copper-covered laces are treated with a brass brush. Solder them with tin-lead solder.
Electroplating metallic lace is to apply a decorative layer of silver or gold, or in oxidation.
