1. A process for producing a glass melt, comprising the steps of:melting glass in a first stage;refining the glass melt in a second stage, the glass melt having a polyvalent ion content of at least 0.5 wt. %;homogenizing and conditioning the glass melt in a third stage; andraising the temperature of the glass melt to at least 1700° C. prior to said homogenizing and conditioning step. 2. The process of claim 1, wherein said raising raises the temperature of the glass melt to at least 2400° C. 3. The process of claim 1, wherein said refining step is conducted at a temperature of between 1800° C. and 2400° C. 4. The process of claim 1, wherein said polyvalent ions comprise one or more ions selected from the group consisting of vanadium, cerium, zinc, tin, titanium, iron, molybdenum, europium, manganese, and nickel. 5. The process of claim 1, wherein said glass melt is free from toxic refining agents. 6. The process of claim 1, wherein said refining step is conducted by heating the glass melt in a crucible using an induction coil. 7. The process of claim 2, wherein said refining step is conducted at a temperature of between 1800° C. and 2400° C. 8. The process of claim 2, wherein said polyvalent ions comprise one or more ions selected from the group consisting of vanadium, cerium, zinc, tin, titanium, iron, molybdenum, europium, manganese, and nickel. 9. The process of claim 3, wherein said polyvalent ions comprise one or more ions selected from the group consisting of vanadium, cerium, zinc, tin, titanium, iron, molybdenum, europium, manganese, and nickel. 10. The process of claim 5, wherein said polyvalent ions comprise one or more ions selected from the group consisting of vanadium, cerium, zinc, tin, titanium, iron, molybdenum, europium, manganese, and nickel. 11. The process of claim 2, wherein said glass melt is free from toxic refining agents. 12. The process of claim 3, wherein said glass melt is free from toxic refining agents. 13. The process of claim 4, wherein said glass melt is free from toxic refining agents. 14. The process of claim 1, wherein said refining step is conducted by heating the melt in a crucible using an induction coil. 15. The process of claim 2, wherein said refining step is conducted by heating the glass melt in a crucible using an induction coil. 16. The process of claim 3, wherein said refining step is conducted by heating the glass melt in a crucible using an induction coil. 17. The process of claim 1, wherein the glass melt is contained in a crucible made from one of platinum and a platinum alloy in said homogenizing and conditioning step.
