A vintage hand crafted glass balls paperweights. The first paperweight has a white cameo image of a mans bust, possibly a historical figure. The cameo is embedded in clear glass that contains red and white glass flecks. The second paperweight features a swirl of blue, red, green, yellow, and white glass. The third is a Italian Murano Millefiori paperweight featuring floral design. The last item featuring a white single flower surrounded by multicolored glass flecks. They made using a technique called blown glass with inclusions. This process involves melting clear glass, adding tiny pieces of colored glass, and then blowing the molten glass into a sphere. The colored glass fragments get trapped inside the clear glass as it cools, creating unique patterns and colors. European Art Glass Table and Desk Wares, and Home Decor, and Collectibles.
