As much as we love our Pyrex -sometimes a little “swinger” action is necessary to keep things fresh and new in our Pyrex relational space! To say “blog coveting” these lovely Federal Glass Circus mixing bowls (from the 1940’s) – for years, is an understatement! Finally found these lovelies to ad to our collection! Maybe we are no longer Pyrex-preservationists, BUT Pyrex-swingers??!!
