Supposedly it is to era. We have about pieces of all across the board, makers, s through today custom pieces by out friends the Melting Point in Sedona, AZ and have showed to many appraisors, glass collectors and no one has ever seen anything this magnificent, well made, beautiful, heavy for a lidded goblet, or chalice. Maybe someone here can help us please?? Recently I checked irradiation with the Geiger counter. What kind of emission is this?
I was told that this alpha emission which is harmless. However, information on the website indicates that this is beta and gamma at low doses. If low doses why I have cpm? I will greatly appreciate you opinion. Have you ever seen pink vaseline glass? Building a Blacklight Display Case for all my Glass…. Just picked up a Geiger counter to check background and other things. To my surprise my wife had a old orange ceramic pumpkin candy dish or cookie jar with a plate for it to rest on.
I was checking a closet full of vases and dishes for radiation. Well this pumpkin lit up my Geiger to cpm and had a 2. Now I stay away from it. Actually all radioactive materials increase your risk for cancer. The greater the exposure the greater the risk. So if you own vasaline glass simply keep at at distance 6 feet from where people live and sleep. The glass can also emit some radon gas so the simple solution is to store the glass in a plastic bag.
Then open it up outside to let gas out. The Orange Fiesta wear is another matter. This should not be stored in living space at all. Way to radioactive and radon emitter. I keep items like this in a locked old fridge outside. I inherited an old vintage art deco floor lamp. It is topped with a matching jade green finial. I do hope the size and amount of glass in this is safe in tightly insulated house. Also, does anyone know the value of such a piece?
Thanks, John! Just recently, I started collecting vaseline glass. I love it!! Thank You!! Why are you bothering to bring up radioactivity in vaseline glass if it is well known to be so low in radioactivity as to be non-existent in terms of ever having any negative health effects?
Consider the source of these opinions as to UR safety levels. After all, this is an article on a collectors website, not a scientific journal. Some furniture coasters are made of this opaque glass and represent an inadvisable risk.
Same with bedside lamps or similar proximity , candy dishes, or anything for actual food storage. Six years later I just read this article and what an excellent read it was! Thank you Ben Marks for such an informative yet enjoyable piece. Some of the advice and information here is terrible. This article makes uranium glass sound totally benign, no different to a bed or a banana. That is not true. Unless you actually measure its radioactivity, you have no way of knowing.
I found a milk white glass serving Bowl. When I put a black light to it you can see a crack and the crack actually glows when I looked up to identify the bowl it says it was made in s era and at the Indiana glass company.
Really really interested in finding out some info one way or the other. Excellent article and great photos!! Would love to start a collection but for the lack of space. Since when are beds radioactive, or even comparable to uranium?
This dishware is. For those commenting in disbelief, please… trust science over what random collectors or friends and family with no science background say.
The folks who helped write this article have obviously dabbled in some radiochemistry classes at some point; they probably know a great deal more than you do about the topic. Be more afraid of long-term exposure to the suns radiation or your garden radon which can both actually increase your risk of cancer.
Excellent article! Thanks for this article. Marks, is employed has a history of developing nuclear weapons. In fact, thanks to Ms. I found some Vaseline glass pieces at a yard sale last week.

Ingestion of uranium that has leached into food that has been in contact with the glass.
Landa and Councell evaluated the leaching of uranium into different solutions over a 24 hour period. The glassware they used was designed to hold liquids e.
They determined that the average resulting concentrations of uranium were 0. The highest measured concentrations were 0. They noted that less uranium would leach into solution when the experiment was repeated. The presumed explanation is that less and less leachable uranium becomes available. After estimating the effective dose equivalents for a variety of potential exposure pathways, NUREG concluded that the highest doses would be to the personnel involved in the transportation of the glassware from a manufacturer to a truck distribution center.
Vaseline and Uranium Glass ca. Production Uranium was first used to color glass in the s and it has continued to be used for this purpose with the exception of a fifteen year or so period beginning in World War II.
There are three principal radiation exposure pathways associated with Vaseline glass: 1. Ingestion of uranium that has leached into food that has been in contact with the glass Landa and Councell evaluated the leaching of uranium into different solutions over a 24 hour period.
Pertinent Regulations 10 CFR September When mixed with phosphorescent copper-doped zinc sulfide, radium emits a characteristic green glow:. The use of radioluminescent paint was mostly phased out by the mids.
Today, in applications where it is warranted like spacecraft instrument dials and certain types of sensors, for example , the radiation source is tritium radioactive hydrogen or an isotope of promethium, either of which has a vastly shorter half life than radium. In most consumer products, though, radioluminescence has been replaced by photoluminescence, phosphors that emit light of one frequency after absorbing photons of a difference frequency. Glow-in-the-dark items that recharge to full brightness after brief exposure to sunlight or a fluorescent light only to dim again over a couple of hours are photoluminescent, and contain no radiation.
