Abstract
A fusion down-draw method for making a glass sheet using a forming body comprising an upper part () made of a first material and a lower part () made of a second material, where the first material has lower creep rate than the second material at the normal operating temperature of the forming body, and an fusion down-draw forming apparatus comprising such forming body. The invention is advantageous in that it solves the issues of internal stress and long-term creep issue of a unitary forming body made of a single material such as zircon.
