That's different to dual use being an integral part of the design??

Not necessarily (IMHO). It is a general concept that provides an impetus; a way of thinking, designing and marketing.
There are also examples of dual use being an integral part of the design, from this era and even earlier (late 1800s) in pressed glass. Examples are:
(1) sugar bowl = (2) stand for centerpiece
(1) celery vase = (2) stand for fruitbowl
(1) compote = (2) base for punch bowl
(1) candlestick = (2) top part of three piece epergne
And to Peter - I can remember the circumstances of the purchase of most of our glass. It's part of the entire "charm" for me. Even the on-line purchases are often in my memory - though not as much as the "live" purchases. I recall my first eBay purchase. It was an Australian berry bowl (Carnival Glass) in the rare "Kiwi" pattern. What a thrill that was.
