Traditional

These forms were created using the traditional glass blowing process using molten glass from a furnace set at 1150c, shaped with wooden, metal tools and wet newspaper, and then blown into a plaster blow mould mixed with sawdust and toilet paper pulp to keep the mould damp and prevent it cracking during the process. The mould was formed around a 3D printed PLA object. The glass is then cooled slowly in a kiln to avoid cracking. After the excess is sawed off and ground down, finished with a polished rim.

Process & Production

The Vortex Whiskey Glasses were created using a combination of traditional and digital making. The form was designed on CAD, and 3D printed, and a blow mould was cast around the printed form. The recipe is a mixture using plaster, sawdust and toilet paper pulp (see link to video tutorial), this allows the mould to remain damp when blowing into it, and prevent cracking.

The molten glass is gathered and shaped before being blown into the mould, the final shape is then put in a kiln to cool down slowly to prevent cracking. After it is worked in its cold state in a process called cold working. The excess is sawed off, the rim ground down and finally polished.
