Vorliegende Erfindung bezieht sich auf das bekannte Verfahren zum gleichzeitigen Biegen von mehreren aufeinander liegenden Spiegel-' glasscheiben durch Auflegen der Scheiben auf eine gekrümmte Formfläche und Erweichen und Anschmiegen der Scheibe an die Formfläche; um mehrere Scheiben zugleich auf derselben Form biegen zu können, müssen sie durch ein das Anhaften verhinderndes pulveriges Mittel getrennt gehalten werden. Als trennendes Mittel wird nach vorliegender Erfindung fein verteilter Asbest verwendet, welcher das Zusammenschmelzen oder sonstige gegenseitige Einwirkungen der Spiegelglasscheiben in vollkommener Weise verhindert. Asbest zu verwenden, um das Anhaften erweichter Glasflächen an anderen Flächen zu verhindern, ist an sich bekannt.The present invention relates to the known method of simultaneous bending of several mirror glass panes lying on top of one another by placing the panes on top of one another onto a curved mold surface and softening and snuggling the disc to the mold surface; by several slices at the same time To be able to bend on the same form, they must be prevented from sticking powdery agent must be kept separate. Finely divided asbestos is used as a separating agent according to the present invention used, which is the melting together or other mutual effects of the Mirror glass panes prevented in a perfect way. Use asbestos to prevent sticking Preventing softened glass surfaces on other surfaces is known per se.
