Abstract
A crucible assembly is suited for use melting aluminum cans at a campfire or similar fire. The crucible assembly may include a handle design that facilitates safe and easy handling of the crucible after it has been heated and contains melted aluminum. The crucible assembly may also include a portion having a convex surface that maintains contact with the ground during rotation of the crucible, thereby providing support and stability to the crucible as melted aluminum is poured therefrom.
Claims9
An apparatus comprising:
- a crucible;
- a shaft operatively connected to the crucible;
- and
- a handle assembly operatively connected to the shaft;
- wherein the handle assembly includes a first portion, a second portion, and a third portion;
- wherein each of the second and third portions defines a respective first end and a respective second end;
- wherein the second portion defines a first concave surface;
- wherein the third portion defines a second concave surface;
- wherein the first and second ends of the second and third portions are mounted with respect to the first portion such that the first concave surface cooperates with the first portion to define a first open space and the second concave surface cooperates with the first portion to define a second open space;
- and
- wherein the second and third portions form an angle therebetween, said angle being between 110 degrees and 170 degrees.

2 more elements
A method comprising:
- possessing a crucible assembly having a crucible defining a substantially planar base surface, a shaft mounted to the crucible, and a support member defining a convex surface mounted to the crucible such that the convex surface is substantially contiguous with the planar base surface;
- placing solid aluminum in the crucible;
- causing the aluminum to melt by placing the crucible in heat transfer relationship with a wood or charcoal fire;
- placing the base surface on the ground;
- and
- rotating the crucible such that the convex surface contacts the ground and the melted aluminum is poured out of the crucible.
