Double glass system

A double glass system comprising:

• a solution tank for containing a solution to be supplied into an interior of a double glass;
• a solution pipe connected between the solution tank and a bottom of the double glass, for supplying the solution from the solution tank into the double glass or for discharging the solution from the double glass to the solution tank;
• an air pipe connected between the solution tank and an upper portion of the double glass, for supplying the air into the interior of the double glass or for discharging the air from the interior of the double glass;
• a pump installed on the solution pipe, for supplying the solution from the solution tank through the solution pipe into the double glass, and for recovering the solution from the double glass into the solution tank;
• a control means connected to the pump, for controlling the pump;
• and
• the solution to be supplied into the double glass being an incombustible solvent with a pigment added therein, a combustion-resistant solvent with a pigment added therein, or mercury.

A double glass system comprising:

• a solution tank containing a certain amount of mercury to be supplied into a double glass, and containing air over the mercury;
• a solution supply pipe connected between the solution tank and a bottom of the double glass, for supplying the mercury from the solution tank into the double glass;
• a solution recovery pipe connected between an upper portion of the double glass and the solution tank, for recovering the mercury from the double glass (if the mercury is overfilled in the double glass) into the solution tank;
• a heat-generating device for generating heat to cause thermal expansions of the mercury and/or air within the solution tank so as to supply the mercury from the solution tank through the solution supply pipe into the interior of the double glass,
• a control means connected to the heat-generating device, for controlling heat generations of the heat-generating device;
• and
• a key inputting means connected to the control means, for inputting command codes into the control means.
