A method of making flashed glass in continuous sheet form, comprising: heating a first quantity glass with one color and a second quantity of glass with another color to the molten state; separately introducing each of the differently colored molten glass into a vessel adjacent to a pair of counterrotating forming rollers such that the differently colored molten glass contact each other along an interface to form a laminated molten glass mixture having two different colored layers; feeding the laminated molten glass mixture into the feed side of the pair of forming rollers which press the layers of the laminated molten glass mixture together into a continuous laminated plastic elongated sheet; stretching the continuous laminated plastic elongated sheet in the machine direction, i.e., the direction of sheet travel produced by the forming rollers; simultaneously with the stretching in the machine direction stretching the continuous laminated plastic elongated sheet in a direction transverse to the machine direction; and annealing the stretched laminated plastic glass sheet. A method of making cathedral glass or the like in continuous sheet form, comprising: heating a quantity of glass to the molten state; introducing the molten glass into a vessel adjacent to a pair of counterrotating forming rollers; feeding the molten glass into the feed side of the forming rollers which press the molten glass into a continuous plastic elongated sheet; stretching the continuous plastic elongated sheet in the machine direction, i.e., the direction of sheet travel produced by the forming rollers; simultaneously with the stretching in the machine direction stretching the continuous plastic elongated sheet in a direction transverse to the machine direction; and annealing the stretched plastic glass sheet.
