Abstract
There is disclosed a process for producing continuous, multicolored glass objects, such as stained glass windows without leading, which includes blowing a glass object, maintaining at least one colored pattern piece in contact with the surface of the object until the pattern piece becomes soft enough to be blown and then blowing the object to a final form whereby the pattern piece becomes incorporated in the glass object. Sheet material may be produced by blowing a cylinder, splitting the cylinder and flattening the cylindrical wall.
Claims11
A process for forming a continuous, smooth-surfaced, multicolored glass object comprising:
- A. forming a gather of glass at a temperature at which it can be blown,
- B. blowing an initial hollow object from the gather,
- C. placing a colored pattern piece in contact with the surface of the initial object while said initial object is at a temperature at which it can be blown,
- D. maintaining the pattern piece in contact with the surface of the initial object for a time sufficient for the pattern piece to reach a temperature at which it can be blown, and
- E. blowing the initial hollow object only to the extent to produce a second hollow object having said pattern piece integral therewith and said second hollow object having a size and shape such that said pattern piece has a predetermined shape which is not substantially distorted from the original shape of said pattern piece.
