FABULOUS end of day coloring, a mix of oranges and milkglass.   This piece does not have a sticker but it does resemble art glass ashtrays from Imperial Glass.  This type of glass was made with layers of colored glasses swirled together.  This was coined end of day because glass workers used whatever was left before cleaning out the melted glass holders and mixed them together to form unique individual patterns and shapes depending on the glass used and artist.  This piece has a wonderfully soft looking matte finish.
