New Martinsville made their stylish Radiance glassware from 1936 to 1939 in crystal plus rich colors of the era, ice blue, red, amber, some cobalt blue, pink and green. The pattern features large, solid handles with scalloped edges as with this creamer.
Pieces have small scallops on the rim and the short flared ribs near the center or bases. The flares show better on this piece
The other characteristic motif is the line of small tear drops that runs up the side of the bon bon base and lid. You can see this tear drop line on this cute amber cordial. Note the horizontal line of tiny flares near the top of the stem.
New Martinsville used Radiance as a blank for several decorations and sold pieces to decorating companies. The top photo shows the crystal creamer with New Martinsville Meadow Wreath etch. This next sugar bowl has the Hughes Cornflower cutting, a cut which you can find on several other patterns too. I am not aware of colored Radiance with etches or cuts.
Radiance pattern line includes dinnerware pieces such as plates, cups and saucers but appears to be mostly an accessory or decorative line. There are pieces like candle holders, a candy dish, comports, vases, cheese and cracker sets, plus a butter dish, cake stand, honey jar, serving bowls, pickle, celery, oval tray.
Radiance is an interesting pattern in both colored and crystal glass and is distinctive for its scalloped, solid handles, scalloped rims, little radiance flares and tear drop trickles. If you enjoy it, consider adding a piece or two!
