Purple pinkish glassware - believed to be German

I have approximately 6 of the cups/vases and 1 of the bowls.  These items have a pinkish-purpleish color to them and have lines/marks running from the base up to about ¼ to ½ way to the top of the items.   These items were brought to the US from Germany shortly after WWII.  A family member in the service brought these items back from Germany in the mid 1940's.  Story has it that these were recovered during a US raid on a Nazi hideout by a family member.  I also have a set of silverware with the initials "EB" and a set of plates recovered during the same raid and brought back to the US.
