Minimization of contamination is particularly important in the preparation of semiconductors and special glasses. A technique is presented in which contamination from the crucible during melting is avoided by suspending the material in high pressure gas. A particular application is the production of perfect spheres. The figure shows a perfect sphere of polyethylene formed by melting a cube like that on the left.
