Two cube goldfish

Object made entirely by hand, structured in two phases.
 Initially the master creates the goldfish using the "lamp" technique,
 subsequently the fish is submerged inside a quantity of transparent glass which is then modeled into a cube.
 A lot of experience is required above all to respect the phases in which the glass can be submerged, if only you were wrong for a few moments the glass would break due to the thermal shock.
