Thopre's etched florals were unquestionably more interesting and elegant than most of her competitors, and her later minimalist pieces decorated with silver are now the most collected for that style of glassware (pictured at right). Her work has aged well, still seeming contemporary half a century after being made. But aside from these two highly visible designs Thorpe experimented with and produced many dozens of other patterns and products in both glass and ceramic.
In the relatively unknown category is a pattern I've taken to calling "Midcentury Mayan" (since I've yet to see anything with an actual name reference). It is hard to find, but it's a rich and vibrant pattern that has been overlooked by collectors and mid-mod aficionados. Featuring an etched labyrinth motif, the feeling of the design is part Oscar Niemeyer, part Mesoamerican with an atomic twist. The motifs repeat subtly, and give the impression of being from a mysterious civilization.
The etchings are deep and hard-edged and appear to be acid-etched—in contrast to her earlier florals which are softer, have gradations, and are known to be sand-etched (which is similar to sand-blasting on a smaller scale). The DTC mark is connected in some pieces to the pattern by a thin line and you can see seams where the stencils were joined (bottom right picture at top shows these details), also indicative of acid-etching.
Like most of her pieces the glassware bases are sturdy, simple, and balanced and serve to highlight the etchings well. These were made around the same time as some of the other geometric patterns since they appear on the exact same bases and shapes, and I've seen glasses (like these of Etsy seller elefant design), pitchers (here, on ebay), and plates and platters with the markings.
Overall, it's a really eye-catching pattern with great potential to mix in with a wide variety of decor styles, from the obvious ones like midcentury modern and space age, to those less so like bohemian and tribal.
