It is a small story about the production of our findings. At the photo above you can see prior results of our work- casted bronze products, but they are not processed and crude yet.
So, everything starts with building up of wax "tree ". The "tree " looks so finally-
Then these "trees " are placed to the casting boxes and filled up with special gypsum. It is the result -
Then casting boxes ,where our "trees " are formed, we put into the furnace for calcination for 10 hours. They are heated up there, wax burns out and emptiness is appeared instead of it. The emptiness will be filled up with metall further. The casting boxes in the furnace look in such a way -
Then we take metall of necessary weight (it is calculated on a formula ), we melt it to this temperature -
Then we get the casting box ,which is calnicated and heated up to 620 degrees,from the furnace
and place it to molding camera,
We switch on the pumping of vacuum and it is the most interesting moment now. We reach a crucible with melt metall from the furnace and fill in metall into a casting box.
After we take heated up casting box and place it into water.
The tree is made from metal now, it drops out and we take it to pieces.
