This vase is blown, irridised, cold worked with rusted iron finish and stands 37cm high.Denizen Glass Design is created by Robert Wynne with each piece being individually crafted to the most exacting specifications by highly skilled artisans working under his creative direction.
Denizen Glass Design is one of Australia’s most respected glass studios, represented in many prominent collections both nationally and around the world.
Rob begins with a cake-mix called “the batch”; a combination of sand (silica), sodium, potash and potassium carbonate. Additives are used to stabilise the batch, reduce bubbles and increase workability. Various mineral oxides, including copper, silver, cobalt, gold and nickel are added if colour is required. The batch is melted in a special furnace at temperatures around 1280 degrees Celcius.
Molten glass is gathered on the end of the glass blower’s most important tool, the blowpipe. This gather of glass must be turned constantly or it will drop to the floor like honey from a spoon.
As the hot, pliable glass is exposed to the air it cools gradually and stiffens, and must be reheated at intervals in a special chamber called the glory-hole.
Hand tools, such as cold steel plates, wet newspaper and wooden blocks are used to shape the formless molten glass as a bubble is formed and slowly blown larger.
Finished pieces are placed in a kiln to be “annealed”; cooled gradually from around 550 C to room temperature so as to resolve internal stresses and ensure they don’t crack.
