I purchased these three vases over a period of the past eight years. When I bought them, all three were attributed as "Rindskopf Oil Spot" decor. On the left is a 5" bowl. The second photo is a 9" vase, and the third and fourth photos are of an 11" vase. All three have the same dark amethyst base glass. All three have similar pontils and show signs of base grinding for leveling. All three have an identical polished quatrefoliate ruffled rim.
There is evidence supporting a Rindskopf attribution for these, but there are also other oil spot vases, both in amethyst and cobalt base glass, attributed as Kralik Astrolit. I am interested in hearing discussion from those who may care to offer an opinion regarding this topic. My current belief is that these three examples are by Rindskopf, but I don't doubt that there may be other similarly styled oil spot glass that may be by Kralik or even other makers. Please feel free to offer advice in the comments section below. I will offer two comments after I post this main article to an example of a known Rindskopf decor in a similar shape as the third vase, and to examples of what is identified as Kralik Astrolit.
