Significant advances in float furnace design and operation, in the development of glass compositions, and in the glass forming process itself have all played a role in the optimization of glass manufacturing. For example, thermodynamic modeling assists with the enhancement of glass composition and offers control over devitrification characteristics, and studies examining burner design, to ensure flames have maximum luminosity and impinge on the glass at the correct angle, aid the minimization of fuel consumption. The exploitation of such advanced research allows glass manufacturers to reduce their expenditure on fuel, decrease their defect rates and produce glass of the highest quality, all of which are important if they are to retain their commercial standing and customer loyalty.

Question: Glass of a higher quality is produced when the float furnace is at its maximum temperature.
Options:
A. true, B. false, C. uncertain
Answer: "C"
