Proposed three-part conduit transfers pure silicon between crucibles. Four-strip heater augments layers of insulation to prevent molten silicon from cooling and solidifying during transfer. Since melt is maintained at temperature relatively close to fusion point, to minimize quartz erosion, even relatively-minor heat losses precipitate solidification and terminate work in progress. Several crucibles may be fed through conduits from central crucible. Each would be contained in its own compartment under inert atmosphere.
