The invention relates to the production of decorated products, mainly slabs, wall panels made of foam glass.

There is a method of decorating foam, providing for the filling of pores on its surface decorative powder material (crushed glass) with subsequent heat treatment [1]. This method assumes that the heat treatment of the products is carried out at a temperature equal to or higher than the forming temperature of the molten glass. Due to such heat treatment under the influence of the temperature is possible deformation of the articles of foamed glass.

The objective of the invention is to reduce the temperature of the heat treatment of the decorated foam glass.

The technical result is achieved by the fact that by way of decorating foam, providing for the filling of pores on its surface powdery decorative material, with subsequent heat treatment and cooling, as a decorative material used ground to the specific surface 1000-5000 cm2/g waste processing of amber.

The method is illustrated by examples.

1. Waste processing amber milled to produce a powder with a specific surface area of 4500 cm2/, Obtained by the powder fills the pores on the surface of the foam and hold its heat treatment in the temperature range of 250-300°C. When the volume of particles amber melt, the resulting melt fills the pores. Decorated product is cooled to room temperature.

2. Waste processing amber milled to produce a powder with a specific surface area of 1000 cm2/, Obtained powder fill (stencil) pores on the surface of products made of foam, for example in the form of a drawing, and hold its heat treatment in the temperature range of 250-300°C. and the particles of amber melted, fill the pores with the formation of the figure. Decorated product is cooled to room temperature.

The method is not complicated, allows to obtain the original articles of foamed glass.
