Use paint brush, applicator bottles or tooth picks to apply the glass powder.
Once the glass powder has been applied and is fully dry, place painted sheet on top of remaining fusing glass sheet.
Put glass on prepared glass kiln shelf.

If using thinfire paper leave kiln door or lid slightly open whilst paper binders burn off and then close kiln.
Hold at this temperature for fifteen minutes.
Bring glass kiln temperature up to 1500° F reasonably quickly, hold for about fifteen minutes or until glass powder is fully fused.

After holding for sixty minutes turn off kiln and allow fused glass coaster to cool down to room temperature.
The above techniques can be used on various sizes and styles of glass.
