Abstract
This sheet production apparatus comprises a vessel defining a channel configured to hold a melt. The melt is configured to flow from a first point to a second point of the channel. A cooling plate is disposed proximate the melt and is configured to form a sheet on the melt. A spillway is disposed at the second point of the channel. This spillway is configured to separate the sheet from the melt.
