I am not a purist when it comes to my Blenko collecting. I am into collecting to enjoy and to have fun. I don't buy glass for resale purposes unlike some others that occasionally post here. When I no longer have fun collecting that is when I will be done. If someone wants to call a 573 a teapot then they should be allowed to do so. I had a friend call me tonight and said it looks more like a coffee pot. I just hope no one out there would think about putting boiling water in any piece of Blenko. Also unlike a couple others I do not wish to see the Blenko company permanently closed. I believe everyone should collect what they want to collect. If it is a 573 "teapot" or a 9316 "face vase" or something made at the company in 2009 then they should buy it if that is what they want. I have always had a problem with being told what I should buy. I personally like Don Shepherd designs but in some eyes the glass made after 1974 is not something that people should invest their money in. Sorry I believe in collecting what you like not what someone tells you to buy.The first picture proves that some people need to let up and start enjoying Blenko and life ! As you can see in the picture I am NOT a purist otherwise I would not have used crystal punch cups with a chartreuse handle to serve the tea along side a Teal 573 "teapot, coffee pot, cocktail pitcher"The 2nd picture is for those that think the 573 can be just a coffee pot.Life is short, Enjoy it!
