Colored frits were combined and mixed thoroughly in a lidded container with enough volume of color to use the base colored glasses to a percentage of clear as shown above.  Use a N95 respirator when using dry glass, especially powders.  Once the frit is wet using a pate de verre glue.  I tend to mix dry frit and powders outside under cover as fine particles the eye can not see remain in the air for 8 hours.  I have track lighting which is how I discovered the finest of particles in the air.  Another reason to wet mop my area after doing art.
