Ninth Period Mark - Jan 1997-Dec 1999

9th Period Mark or 2nd Blue Mark. This change was made due to purely technical reasons. There were a lot of problems with the first blue mark with parts of the mark burning off during firing. This resulted in a lot of pieces having to be re-fired with obvious added costs. New artwork for Belleek packaging had been developed around the same time and it was decided to use the opportunity to match both together. Looks like old 1st period mark but again has registered trade marksmall R. They also used to types of this one with the words "IRELAND" and one with EST 1857, under the word Belleek.
