Wheaton NJ has for many decades been a combination museum and glassworks, keeping alive the traditions of the South Jersey glassblowers. In keeping the traditions going, they keep the fires lit and produce stuff...giftshop stuff, etc. They are not meant to be reproductions competing with real rare collectors' bottles. You can think of them as decorator items or teaching models. Most are not exact duplicates of real rare bottles, so there should not be confusion among antiques dealers & collectors. But, like Fenton, there are some collectors who will pay a few dollars for Wheaton products because they are examples of keeping a dying craft alive. [By the way, the craft is coming alive again at Fenton; follow this connect for the story...
