Millefiori is Italian for 'thousands of flowers'. When you look closely at these little glass bits, you'll see not only flowers, but hearts, suns, circles and maybe a few other little random shapes. This is COE 104 glass, if you're interested in using them in your next fusing project. They're also cute enough to be used in any standard mosaic. They measure 5mm - 6mm in diameter. The slice thickness is fairly irregular, ranging from about 1mm thick to 5mm or 6mm thick, with most pieces hovering closer to 3mm - 4mm thick. Many slices are a bit slanted, as well, making each piece truly unique. Hover over the 2nd image to see this color used in a completed project.
