I made a similar window several years ago, but with grout. This is the same idea, but with resin instead of grout. Made with Spectrum Iridized blue and Dichroic glass. 30.5″ w by 27″ h. I love Dichroic glass, but it is very expensive. At approximately $3.75 per square inch, I think I have approximately 112 square inches of Dichro glass in this window.
