Fenton Or Mosser? Diamond Optic In Violet Rose Bowl 4" x 4" I BELIEVE IT IS MOSSER BECAUSE OF THE PATTERN EXTENDS AND COVERS THE BOTTOM AND FENTON DID NOT USUALLY DO THIS, THIS ALSO LOOKS LIKE ITS A HAND BLOWN ROSE BOWL, FENTON PRESSED THERE'S IN A MOLD AFTER BLOWING THE GLASS, BUT I DID READ THAT FENTON DID MAKE A FEW PIECES THAT DID NOT GET PRESSED BUT HAND BLOWN.  SO YOU Decide who made it.  it also looks like someone tried putting a logo on the bottom but had a hard time because of the pattern on the bottom.  this is Diamond optic which is one of Fenton's pattern and it is purple Violet IT IS NOT CRANBERRY  it just looks that way through pictures.  the first picture is like that so you can actually see its purple.
