The invention provides frame glass prepared through medium-high frequency induction heating and a preparation method of the frame glass. The preparation method comprises the following steps that glass preparation raw materials or/and cullet is/are mixed, poured to a metal frame and heated through a medium-high frequency induction heating coil to be molten, and finally cooling molding is carried out. By means of the method of preparing frame glass through medium-high frequency induction heating, on one hand, the metal frame can be sufficiently utilized for high-frequency heating, and on the other hand, installation of the glass is facilitated by the metal frame arranged in the glass. In addition, the mechanical property of the metal frame glass is greatly improved, and the metal frame glass can be prevented from being broken in the transportation process, can also be used for installing a glass door, and has an anti-theft function.
