Your items are part of a Castor set. They are Vaseline glass. Many glass companies didn’t mark there glass for different periods of time. I don’t recall ever seeing vaseline glass within a castor set. Those would be oil and vinegar holders. They may be reproductions. I would google Vaseline glass, also Castor sets, & oil and vinegars to see if there are any others out their.

vasaline glass is usually opaque and not see through… I believe it to be green glass or depression era glass

I agree totally with Barntiques and have never seen vaseline glass with original castor sets.

They are bottles that go with a castor set. If you lived in the south there may be pickled peppers, oil, vinegar, hot sauces found in these bottles. Southerners loved their pickled vegetables.

I agree with what Barns said.

BTW- if it is green glass it is not vaseline glass.

I love glass but am not an expert, it looks a lot like vaseline glass from your pics. Your pics are not clickable so I can’t see them up close, like to look at a pattern. Any marks on the bottom? They make me think of vinegar jars I have seen in the past. Again, I’m not any kind of glass expert, I just like it a lot.

Need better pix dear.
Close up of pattern, and measurements too.
Try on a white background, and better yet, roll a piece of white paper
into a tube & slip inside, so we can see the pattern.
Don’t use flash, it messes with the true color.
Check the bottom too, for marks.

The color doesn’t look like Vaseline glass, but it still may be old. An easy way to tell is to put it under a good black light (tube style, not bulb). If it is depression era glass, it will glow due to the manganese used in the glass during its production. If it doesn’t glow like green fire, then it probably isn’t old. The pattern looks like thumbprint, but its hard to tell. Many libraries carry glass identification books, so that’s a good place to start your research. My personal guess from the photos (which are kinda small), is that they are probably not that old, but I am just guessing. Good luck in your research, and have a great day (or evening as the case may be!).

Thank you all , It did glow under the black light. This a picture of a castor set in vaseline glass by Duncan Miller…wow they did make it in castor sets…

Probably modern production glass. Uranium is added to give the green / yellow black light glow. Older “Vaseline” glass was usually yellow in normal appearance.

Unfortunately for a lot of collectors, look alike glass has been massed produced lately, and has been flooding the market.

This all makes the glass collectors area of the market very shaky and buyers must be wary of all the “not so old” pieces available,

Good luck with whatever you have there.

Vaseline glass will glow under a blacklight. Bought a desk lamp, put in a black light bulb and test my glass that way.

Hold up a mini black light- vaseline glass is just what it is- and collectors adore the rare!

BTW, in answer to your question, not all glass is marked but you can find some wonderful research books online. They will give examples of their patterns, glass type, shape, etc.

Go to some of the vintage glass sites and they usually have a good reccomendation on books.
