The antique French opaline pieces are quite rare, and costly, as you can imagine. Larger pieces are so coveted, it is almost impossible to get collectors to sell any, so finding larger vases or centerpiece bowls is always a true treat. Many opaline pieces were made as souvenirs, boxes, sugar caskets, egg boxes for holding jewelry or showing off a gold pocket watch. Others were useful objects of grander size such as covered candy containers, vases, urns, and compotes. But much opaline was created as objet d'art, admired just for their sheer beauty.
The most collected and admired color of opaline is robin's egg blue, although lemon yellow is considered the most rare color of all as fewer pieces were produced in that color. Very early antique French opaline such as this rare to find pair of robin's egg French blue vases with hand painted gold stars are especially sought after by collectors. This pair of vases is special because of their large size, most of the ones like this still in one piece today are 6" or smaller.
As with all Vallerysthal Portieux colored glass pieces, the lighter robin's egg color is almost unique to them. It is an aqua turquoise which was created by using additions of copper oxide to the batch of crystal with varying amounts of other non-metallic elements.
Opaline was very popular again in the 1920's - 1960's and was produced most notably in drinking goblets and table type wares. Opaline remains pretty rare to find, with the really old French pieces being almost impossible to find. There isn't much information on the history of opaline or the provenance of the antique pieces, the only two books I've ever found are in French.
The blue opaline comes in a variety of shapes and sizes. I was thrilled to find everything from small saleron {salt and pepper} all the way up to the most exceptional large blue opaline vases made in the 1800's with hand painted gold stars.
You don't need to amass a huge collection of opaline to enjoy it at home. Even a single piece of antique French opaline will make your interior sing....and make you smile each time you see it. One piece is just as gorgeous as a bunch of pieces are. I will warn you though, once you have bought and owned a single stunning blue opaline French perfume bottle and placed it on your vanity or in your bathroom, you may need more!
This perfume bottle has a unique top, featuring a painting of a French landmark under glass. Made as a Grand Tour souvenir, these are getting more and more difficult to find. The top flips up, and underneath there is a tiny stopper. So wonderful!

Do you know if they produced any pink opaline?

Laura, an antique opaline box should definitely not look brand new. There will always be some signs of age, whether it’s a soft sign of marks on the bottom, the corners, or some patina on the gilt ormolu metal parts and closure. Some antique boxes can have their metal polished by a professional to almost new looking condition. The best way to know if something is an antique is first to go out and see some in person, touch them and get a feel for them. And second, be sure to buy from an established dealer with a stellar reputation. {I’ve seen some lovely vintage Italian glass boxes this summer at market in Europe that are wonderful, but definitely not 100 years old and worthy of some of the prices being asked.}

How can you tell if opaline glass is truly antique? I’ve seen some beautiful boxes popping up everywhere suddenly and they look brand new but are said to be over 100 years old. I’m wondering if there are reproductions being made now. It seems there is no way to identify if it is a true antique.

Annie, I am not an expert on glass, but while Opaline glass is antique, I believe Opalex glass is more like milk glass and made in the 1950’s and later. Either way, I’m sure that your bowl is a treasure!

Is opaline the same as Opalex? I have an Opalex Mixing bowl in blue and I am wondering if it’s connected to Opaline as Opalex was made in France too.

I’m an avid uranium glass collector and stumbled across my first uranium opaline piece yesterday. It’s a very light blue, almost green. I wish there was more information available. I’d love to know if it’s French or not!
