Specific Technique

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 local soil to keep the mould damp and prevent it cracking during the process. The mould was formed around a 3D printed 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.

Culture & Context

The Eorna Whiskey Decanter and Glasses were created especially for an exhibition in the Lavit Gallery in Cork called Lúnasa,  curated by Stephen O’ Connell. Lúnasa is the Irish word for August, and celebrates the harvest festival. The form of the glass was inspired by the barley grain, harvested each year to create whiskey. I created the form on CAD, and 3D printed it before casting a blow mould around the printed form.

 

Normally I create my glass blowing mould 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. This time I used local soil mixed with the plaster to keep it damp. The molten glass is gathered and shaped before being blown into the mould, the final shape is then harvested from the mould, just as the barley is harvested from the soil.
