Interesting pieces. Judging by the lack of uniformity in the thickness of the glass, they are mold-blown, as you say. They sort of look like packaging, but it seems like there's not much place to put a lid or a label, so I'm inclined to think they aren't. It almost looks like the yellowish color was intentional on the non-satin one (I have lots of 19th C Bohemian glass, and none of it is anywhere near that yellow; most isn't yellow at all). If they came from Romania, they aren't Bohemian. Interesting examples of old Romanian mold-blown glass. I'd be surprised (and impressed!) if anyone here could tell you more about them than you already know - I know of no documentation for that sort of thing.
