Corolla/Oorolla By Cerastone 

Look-alike products frequently copy Corelle patterns, but not many are also duplicates of Corelle shapes.  This product has copied Spring Blossom Green as well as the hook-handle cup.

Imitation hook-handle cups.

It is difficult to decide how this brand name is spelled, it certainly looks like a capital 'O', but Corolla makes a more sensible name than Oorolla.  More intriguing is the logo's deliberate attempt to impersonate the Corelle backstamp from the 1970s and early 1980s.  The name itself might not be important, because it is clear that it was chosen for appearance rather than meaning.  At a glance, it can be mistaken easily for 'Corelle'. 

Cup backstamp, Je Il Glass Co.

The other names on the bottom, Cerastone and Je Il Glass Co., belong to a firm in Korea, but nothing else is known about this company or this particular product line.  Glass dinnerware does not seem to be the focus of their business currently.  Whether these cups were part of an entire set of dinnerware is unclear, and how many Corelle patterns were duplicated is unknown as well.

The stamp warns that the cups are not oven proof, so they are probably made of ordinary milk glass.  It is not a complex glass laminate like Vitrelle, and the cups are shaped by conventional glass pressing technology, not thermal vacuum forming as genuine hook-handle cups are. 

Comparing with Corelle hook-handle cup at right.

With conventional glass-forming methods, it would have been natural to make conventional-looking cups with a closed handle, a shape that most consumers prefer.  So it is interesting that the makers of this look-alike brand duplicated the hook-handle shape as well as the pattern to make an even more convincing copy.

The cups are smaller than genuine hook-handle cups, with a diameter of 3½" and a capacity of only 6 oz.  The pattern is very realistic with a good colour match, but a side by side comparison shows that there are differences as well.
