PURPOSE: A hemispherical glass lamp shade mold with a lid is provided to make the edge of lamp shade be leveled by assembling a lid to a conventional lamp shade mold. Also, the edge of lamp shade has various patterns due to shapes grooved on the mold. The resultant lamp shade can be manufactured in a 50-80% saved price. CONSTITUTION: The mold is characterized in that many projections(11a, 11b), corresponding to projections(22a, 22b, 22c) are formed on a lid(10) and a mold(20), selectively, and they are locked each other in an opposite direction to a rotation of motor. Various patterns on an edge of lamp shade are formed with spreading glass melt to the edge of mold having patterns by centrifugal force.
