Dichroic glass is a type of glass that exhibits two different colors when viewed from different angles or under varying lighting conditions. This unique property is achieved through a special coating that is applied to the surface of the glass. The coating is made up of multiple layers of thin materials, often metallic oxides, that reflect and transmit light in different ways, resulting in the appearance of different colors.
One thing I learned recently from Hillary Lawson was to apply the dichroic glass on upside down. In the past, I was applying it on with the glass on top and the dichroic facing my bead, but this method is harder because there ends up being more glass to smooth out. When I did it in reverse, it lays the dichroic glass down cleaner. You still have to encase it, but it just works so much better this way.
