::Using the same technique as used in the production of the Rubberrubberplants plants are cast in rubber. An actual plant is dipped in plaster and left to dry. The plaster block with the plant inside is placed inside an oven and stoked to a temperature of 600 degrees Celsius. During this process the plant is completely vaporized and leaves its shape inside the plaster. This mould is now placed inside the vacuumtank and a small tube is connected to the only opening in the mould. A strong vacuumpump draws all the air out of the mould.
On top of the tank a reservoir is filled with a liquid rubber. When all the air is drawn from the mould a tab is opened and the rubber is pressed into the mould. The lack of air in the mould means that the liquid rubber meets no resistance and can reach even the smallest cavity. No air means no resistance. Therefore there is no need for multiple openings for filling the mould, a single entry is enough, even for the most complex shapes. Because of the vacuum the outside atmosphere (1 atmosphere)presses the liquid rubber into the mould. After the mould is filled up it is left to set and dry for a few hours after which the plaster cast is broken away. The end product is a perfect copy of the plant, including the smallest detail and its natural perfection.
