Lit-Art Company specializes in monumental art casting from bronze, aluminum and cast iron. Besides here they produce plaster sculptures of any size.

First of all they make a full-size model of a future statue.

Sometimes statues are entirely made of plaster – they prepare a  scale copy first, where measuring points are marked.

Then, using these measuring points, they make a basic frame.

Subsequently it is covered with plaster but the statue remains hollow inside.

This statue is taped after the initial shaping.

The workshop of art casting.

These are wax models of a statue separate parts being made.

Here, in plaster forms, the wax models are getting colder. Then they are filled with special fixing mixture containing pitch and sand.

A lump form made of this mixture is dismantled. The wax is removed manually. The interior surface of the dismantled form is covered with non-paint stick. The cavities, from where the wax is previously removed, are filled with molten metal.

Fixing mixture making.

Working process.

All workpieces are transported in the workshop with help of electric winches. Lighting up – on the right.

One full tank is finished for about 10 minutes in a furnace.

Molten metal is poured out from the boiler and “the skin” is removed.

Filling the forms prepared in advance.

There, at a distance, is a shop for finish work with bronze workpieces.

The process is repeated.

Filling again.

Hot!!!

The metal should get cold.

The remains are poured in the furnace again.

Separate parts are assembled into one solid statue. It is made with hot gas welding.

A ready statue.

Something is sawn off, something is welded on, and then all that is ground.

The result are such sculptures.

The work is quite laborious but very impressive!
