Operating out of a furnace that contains clear molten glass with a working temperature of 1150ºC, each piece starts out by gathering a small piece of molten glass on the end of a blowpipe made of tubular steel.
After initial shaping of the molten glass our colouring process begins. Using powders, grits, canes and shards of various colours, the motifs and designs are applied onto the molten glass bubble at the end of the blowpipe.
When the layers of colour required for the piece are applied onto the initial gather of molten glass we smooth and shape the exterior of the bubble on a steel table called a marver, allowing for even applicaction of further gathers of clear glass from the furnace.
Additional layers of clear glass are then gathered from the furnace to encase the colour and build up the mass of the piece.
The build up of heat in the blowpipe requires for the occasional cooling of the steel in water to aid in the effieient handling of the piece.
Using fruit wood hand tools called blocks the glass is further shaped and centred to ensure an even coating of glass is created.
The bubble starts to be inflated and a wet newspaper is used to shape and centre the piece during the process.
A constriction line is applied to the inflated bubble using a metal hand tool called a jacks to allow for a clean break away from the blowpipe.
Continual re-heating of the bubble in an secondary furnace called a glory hole to ensure the right viscosity of the glass for inflation and to prevent thermal stress within the piece.
Once the bottom of our piece is shaped to our desired design we break off the bubble from the blowpipe and transfer it onto a solid iron called a punty which allows us to shape and open up the rim of the vessel.
The opening of the vessel is then shaped and opened out using the jacks.
Final shaping by hand and a fire polish in the glory hole ensures a beautiful surface quality. The piece is then placed in an oven overnight to gradually cool down to a room temperature.
A grind and polish of the piece to ensure a perfect finish when cold and the final vessel is complete.
