The above picture shows part of a chinaware factory, notice the kiln's in the background. 
One of the difficulties with Arabia’s collection of common unmarked glassware and chinaware is identifying the manufacturer. Although it might be a curse for the collector, it is a gift for the historian.  
The competition between manufacturer’s was brutal, as seen by the example at the bottom of this posting, taken from the Sketch Book of St. Louis 1858. I have two copies of this book with book plates showing the text was property of a hotel and steamboat library. Guests could use these guides for shopping.

Few patents were filed for glassware designs, so other glassworks such as St. Louis Glassworks, which opened in 1854, at 75 N. Second Street in St. Louis could freely duplicate the molds and even advertise doing so (see scan's of their store below). Hence, this store could very possibly have manufactured and sold some of the glassware found in Arabia’s hull.
St. Louis Glassworks ace in the hole was the merchant would avoid paying more by purchasing St Louis manufactured glassware and that could be a deal maker. They claimed,
“We feel confident in asserting that this company can manufacture every variety of glass as cheap, if not cheaper, than it can be done in Pittsburgh….This Company is prepared to duplicate all orders from the Pittsburgh manufactories, thus saving to our dealers the cost of transportation. When this fact becomes generally known, we may look for a marked change in the trade.” 
If you recall in my last blog, my St. Louis salesman visited Pittsburgh, Pennsylvania and met Mr. McKee at his glassworks J & F McKee’s glasswork’s printed in their first catalogue in 1858,
     “As we have our Glass put up by experienced packers, in the most neat and careful manner, we make no allowance for breakage, Bills of Lading being guarantee of good order when shipped…DO YOU WISH TO HAVE YOUR GOODS INSURED? We have an open Policy, covering shipments to all points, at as low rates as can be secured here.”
