U.S. Glass 310 Line
All of the 310 Line items have paired rays on the outside of the pieces. A considerable number of different pieces can be found, including 'open work' pieces. Most of the pieces have snap bases (not ground) or ground maries (the three-footed pieces).
310 pieces are usually found in blue, pink and green. There appear to be three lines that have paired rays. The 310 line has the paired rays on the outside of the piece, often down the foot, on footed pieces, and rounded points where the rays meet the rim. The 314 line has paired OPTIC rays (on the inside) of the pieces. This line also has the rims of pieces flat, without points, and there are always four sets of the rays. A third line is distinctly different, having paired optic rays, usually six sets. These pieces also have distinct points where the rays meet the rim, but the points are not as prominent as the 310 pieces.
The tall candleholders are occasionally found in yellow opaque and blue opaque though the other pieces in these colors are not the typical 310 pattern; they usually have the optic rays and points.
