When I have some free time in the studio in between commissions, I love to play around with different products and techniques.  A few months ago, I found something called photo fusing paper which allows me to print an image, transfer the image to glass, and fuse it in the kiln. I decided to give it a try with an image of my Dutch grandparents, Oma & Opa, taken in Holland in 1933.  (It's noted on the back in my Opa's distinctive handwriting, "Zondag wandeling in Den Haag")  I transferred the image onto a piece of vanilla glass and, after firing, it had become a beautiful sepia tone.  It turns out this is because the coloring agent in the toner is iron which creates an iron oxide, also known as rust!  This technique is a great way to personalize jewelry boxes, holiday ornaments, gifts, and keepsakes.  I think the sepia tone makes old photographs especially beautiful.
