| Ice Glass
|
 |
Ice Glass A decorative technique whereby
the surface of the glass is deliberately made rough and
opaque, like cracked ice by plunging a paraison of soft
glass into cold water early in the blowing process so
that the surface is fussed. After gently reheating, the
final blowing enlarges the web of cracks to create a frosted
appearance. |

to glass by fusing. Inlays may be golden or coloured.

due to oxidation. Artificial oxidation can be obtained
by the action of metallic oxides fumes in a medium heat
kiln. |
