ABSTRACT:
A form for making a glass lampshade constructed by cutting a solid mold having an outer surface of a desired configuration into a pie-shaped section, shaping it so that it will stand on a table with the curved surface uppermost and placing a pattern upon the section of the form. The glass lampshade is constructed using the form by the method of placing colored glass or the like upon the form in conformance with the pattern and securing the glass sections together in a manner well known in the art. Following the completion of one section, an identical section is formed using the same form, and this process is repeated until a sufficient number of sections are fabricated to form an entire shade. The sections are then secured together to complete the shade.
