Description:

The Blow More Glass Tools 5 inch Infinite Rim Marble Mold is a forming mold used to shape hot glass into consistent, round marble and sphere forms. It is built as a rigid mold with a circular forming opening sized for 5 inch work, allowing you to roll and true up a gather while keeping the outside rim continuous so the glass can be rotated smoothly without catching. In lampworking and small-scale hot work, this style of mold is used when you need repeatable diameter, clean symmetry, and a controlled surface while you bring a piece into round before final fire-polish and annealing.

How it is used:

Bring your gather up to a workable heat and keep the surface evenly molten. Place the hot glass into the mold and roll smoothly while maintaining steady rotation to keep the piece centered and round. Reheat as needed to prevent chill marks and to keep the surface moving, then return to the mold to refine the sphere. Once the desired roundness is achieved, remove from the mold, fire-polish as needed, and anneal appropriately for your glass type.
