The materials used by Neptune Hot Glass to create its glass sculptures involve soda lime glass,dichroic glass, various glass powders and frit.The individual parts inside these pieces are produced seperatly for each sculpture. Assembly takes place at about 1200 degrees F when various precious metals are added as the interior of each piece is sculpted. Once the assembly process is complete, the sculpture is encased in clear glass that has been melted to 1200 degrees F in an electric furnace.The piece is then shaped by hand with graphite smoothing pads. The Lagoons are cooled, then cut with high speed diamond wheels, and polished for many hours through eight separate steps. This process results in the mirrored images seen deep within the pieces.
