Certain example embodiments relate to frit materials that have an improved IR absorption property. Certain examples relate to frit materials that substantially melt in about 3 minutes at a temperature of about 525° C. Certain examples relate to a method of making an edge seal by using IR energy. Certain examples relate to adjusting the IR energy applied to a frit material to form an edge seal. Certain examples also relate to making a VIG unit by applying IR energy and adjusting the amount of IR energy over multiple periods of time, e.g., in an oscillating manner.

1. A method of making an edge seal for a VIG window unit, the method comprising: applying IR energy from at least one IR emitter operating at a first voltage for a first predetermined period of time of from 3-7 minutes to a frit material, wherein the frit material along with a plurality of spacers are located between first and second substrates;after the period of time of from 3-7 minutes, reducing the operating voltage of the IR emitter from the first voltage to a second voltage for a second predetermined period of time of from 2-4 minutes so as to reduce the IR energy impinging upon the frit material, the second voltage being between 25% and 75% of the first voltage;after the second period of time of from 2-4 minutes, increasing the operating voltage of the IR emitter from the second voltage to a third voltage for a third predetermined period of time of from 6-8 minutes so as increase the IR energy impinging upon the frit material;after the third period of time of from 6-8 minutes, oscillating the operating voltage of the IR emitter between a first threshold and a second threshold at least two times in forming the edge seal; andcooling or allowing the frit material to cool over a fourth period of time in making the VIG window unit. 2. The method of claim 1, wherein the first predetermined period is between 3 and 6 minutes. 3. The method of claim 1, wherein the fourth period of time is less than 30 minutes. 4. The method of claim 3, wherein the fourth period of time is less than 20 minutes. 5. The method of claim 1, wherein the frit material has an IR absorption percentage of at least 80% in a wavelength range of between 1100-2100 nm. 6. A method of making a VIG unit, the method comprising: providing first and second substantially parallel spaced apart glass substrates, a frit material being provided at a peripheral edge thereof; andforming an edge seal in accordance with the method of claim 1. 7. The method of claim 6, wherein the first predetermined period of time is between about 4 and 6 minutes. 8. The method of claim 6, wherein a temperature differential across the first and second glass substrates does not exceed +/−3° C. during the first, second, and third periods of time. 9. The method of claim 6, wherein the VIG subassembly includes a plurality of support pillars disposed between the glass substrates. 10. The method of claim 9, wherein the frit material is at least initially disposed to a height greater than a height of the pillars. 11. The method of claim 1, wherein the frit material comprises bismuth oxide, zinc oxide, boric oxide, aluminum oxide and magnesium oxide in amounts sufficient to absorb at least 80% of infrared (IR) energy having a wavelength of 1100-2100 nm. 12. A method of making an edge seal for a VIG window unit, the method comprising: applying a first IR energy from at least one IR emitter to a frit material for a first predetermined period of time of between about 3 and 6 minutes, wherein the frit material along with a plurality of spacers are located between first and second substrates, wherein the frit material comprises bismuth oxide, zinc oxide, boric oxide, aluminum oxide and magnesium oxide in amounts sufficient to absorb at least 80% of infrared (IR) energy having a wavelength of 1100-2100 nm;after applying the first IR energy, applying a second IR energy from the at least one IR emitter to the frit material for a second predetermined period of time of between about 1 and 5 minutes so as to reduce the temperature of the frit material;after applying the second IR energy, applying another IR energy different than at least the second IR energy from the at least one IR emitter to the frit material for a third predetermined period of time of between about 5 and 9 minutes so as increase the temperature of the frit material compared to the temperature of the frit material resulting from the second IR energy; andafter applying the another IR energy, cooling and/or allowing the frit material to cool over a fourth period of time in making the VIG window unit. 13. The method of claim 12, wherein said step of applying a first IR energy comprises applying short-wave IR energy having a peak wavelength of approximately 1100 nm. 14. The method of claim 12, wherein said step of applying another IR energy comprises applying short-wave IR energy having a peak wavelength of approximately 1100 nm.
