Air is the best mould for glass, since it is the only material able not to leave marks on the glass. When in contact with air, the glass will have a clear, smooth and clean surface.
This project aimed to expose to air the most amount of molten glass as possible. The tests focused on creating a mould which would behave as a volcano, letting the molten glass slide onto it and harden in contact with the least material possible.
This fragments represent a test where the glass melted on top of a ribbed surface, leaking upon it to cover the volume.
