I recently - on holiday - came across this nice little Richardson vase. I suspected it was American from the similarity to other small vases I have from the USA. As you can see it has a relatively early date and research into Glass artists called Richardson threw up Cathy & Ellen. Cathy however did not start in hot glass until the early 1990's and the other lady only does stained glass now. Then I remembered the other vase I have with this most unusual 4-post pontil.
Sure enough Don Carlson (he of the strongly iridescent vase) had employed a Don Richardson for some 20 years up to 1995. This is thus a Don Richardson vase,
Don Carlson also claims to have invented the device that allows the 4 small pontils. The effect on his vase is really noticeable because the iridescence goes in and around the actual pontils.
