It boggles the mind how artist Carol Milne was able to manipulate glass to look like row upon row of intertwined yarn. You see, the melting point of glass is between 1,400 – 1,600 degrees Fahrenheit, so how was she able to knit the fragile – not to mention very hot – material into intricate artworks?

Milne invented the process herself in 2006. She first makes a wax model of the sculpture, which is then encased by a refractory mold material (that can withstand hot temperatures.) The second step involves melting out the wax with steam and replacing it with pieces of glass. She then heats the mold to 1,400 – 1,600 degrees Fahrenheit, which melts the glass, allowing it to occupy the mold’s empty cavities. The piece is left to cool for several weeks before Milne starts chipping away at the shell to reveal the details of the sculpture.

The result is nothing short of amazing and worthy of this time-consuming process. You can see more of her works over on her Facebook page.
