Abstract
A process for producing a glass body, the process including flowing oxygen gas from a burner in a furnace at a flow rate of greater than 12.0 standard liters per minute and flowing a precursor gas mixture from the burner. The process further including oxidizing the precursor gas mixture with the oxygen gas to form glass particles and depositing the glass particles on a collection cup to form the glass body.

A process for producing a glass body, the process comprising:
- flowing oxygen gas from a burner in a furnace at a flow rate of greater than 12.0 standard liters per minute;
- flowing a precursor gas mixture from the burner;
- oxidizing the precursor gas mixture with the oxygen gas to form glass particles;
- and
- depositing the glass particles on a collection cup to form the glass body.
A process for producing a glass body, the process comprising:
- flowing oxygen gas from a burner in a furnace;
- flowing a precursor gas mixture from the burner at a flow rate of less than 5.1 grams/minute;
- oxidizing the precursor gas mixture with the oxygen gas to form glass particles;
- and
- depositing the glass particles on a collection cup to form the glass body.
