"New Year's Day. A fresh start. A new chapter in life waiting to be written. New questions to be asked, embraced, and loved. Answers to be discovered and then lived in this transformative year of delight and self-discovery. Today carve out a quiet interlude for yourself in which to dream, pen in hand. Only dreams give birth to change." Sarah Ban Breathnach

Trial #5 - Closer Look
The French vanilla fine frit turns a creamy white color after firing unless it is near cyan. These two colors being positioned next to each other is a perfect example of reactive colors. The heat from firing provides the catalyst to activate the chemical reaction between these two frits. Notice in the example below that the places where the French vanilla frit is the most dense, the particles that are not in contact with the cyan frit have turned white but the particles that have ANY contact with the cyan have turned a dirty brown. This layering effect is the easiest to view in the third example below.
In this close-up, the layering effect allowing the surface French vanilla frit to remain untouched by the cyan frit has allowed it to turn white and NOT react.
