Glassmaking Experience Unavailable. Uranium was used by both Japan and western nations as a glass colorant between the 19th and the 20th centuries. The glass made at this museum uses uranium from the nearby Ningyo Pass, and was named “Fairywood Glass” because of how it fluoresces green in the presence of UV light. Although a small museum, we house an exhibition of both uranium glass works from around the world and contemporary glass works, a glass workshop offering glass experiences, and an art shop which sells glass items.
Please enjoy the mysterious glow of the glass. Following the completion of mining in , it was decided that the uranium from the Ningyo Pass would be used as a colorant in creating original uranium glass pieces as part of a plan for regional development centered on unique product development using uranium. Later, designs were drawn up for a museum and glass workshop which could become a center for the development of local industry, tourism, and regional culture: The Fairywood Glass Museum was opened in April

Yellow glass with 1% uranium oxide was found in an ancient Roman villa uranium is million years, making them useful in dating the age of the Earth.
In , it became Adams and Co. Glass Co. These two gypsy tubs are rare to find with lids intact. They also had their own foundry and mold shop for producing molds for. The pattern was originally called No. Baccarat open salt or nut cup , 2. Glass has been documented as being made at that location since They are known for both clear and colored glass.

It is the world’s first museum specializing in uranium glass in Kagamino-cho, currently the oldest uranium glass item in the world with a known production date.
The European definition describes vaseline glass as any kind of creamy yellow glass shading to white with a colour that resembles the original vaseline ointment. In experiments with uranium as a glass colourant were being carried out by Whitefriars Glass Works in London and in a pair of uranium glass candlesticks were presented to the Queen. Also in the 19th century, Davidsons glass produced a glass called pearline that contained uranium and was made with heat sensitive chemicals that turned milky white when reheated, producing a shading effect from yellow to milky white at the edges.
American collectors consider any kind of glass which glows under ultra-violet light because it contains uranium, as vaseline glass. The addition of the Uranium Dioxide makes the glass color yellow-green. Vaseline Glass is always verifiable by using an ultraviolet light blacklight on the glass item. When this is done, the glass turns a bright flourescent green. Sometimes, even the most trained eye can be fooled by a piece of glass that looks like Vaseline Glass, but will not glow or fluoresce bright green under a blacklight.
Manganese is added to the glass mixture to counteract the minor traces of iron that would give the glass a coke-bottle greenish tint. Yellow to yellow-green glass that turns florescent bright green under UV light is the only true verification of Vaseline Glass. The range of makers, styles and age is diverse. Many of the current sources of vaseline glass are American glassmakers, with several of these still in production.
In Europe the use of uranium was almost eliminated after WW2, with the exception of some Venetian glass on the island of Murano. There have been claims that its first use was as early as 79 AD following the discovery in of a glass mosaic in the excavation on a Roman Villa near Naples in Italy but this was never proven.
Uranium Glass Bowl
Each ring is hand-woven with solid Sterling silver wire, then oxidized and polished to an aged, dark silver lustre with faceted uranium glass, stainless steel watch gears and Sterling silver bead caps. They are also completely adjustable and may be worn on virtually any-sized adult finger without sacrificing comfort or style. The band is about 4mm wide.

Vaseline and Uranium Glass ca. Purists might argue that the green sugar bowl in the picture should not be considered Vaseline glass because an additional colorant probably iron has been used in addition to the uranium to produce the green. Vaseline glass is a recent term that probably dates from the s. Uranium glass, an older and more general term, is sometimes used as a synonym for Vaseline glass, but this can lead to confusion because some types of glass colored with uranium e. Canary glass is an even older name that was first used in the s to describe what is now referred to as Vaseline glass.
To confuse matters somewhat, this non-Vaseline glass might even be radioactive due to the presence of thorium impurities! Perhaps the most reliable way to identify the presence of uranium in the glass is to expose it in the dark to a source of ultraviolet light e. If the glass glows a rich green color, it contains uranium. This green fluorescence explains why an example of Vaseline glass that looks yellow under incandescent lighting might take on a greenish tinge when viewed outdoors.
There are exceptions. Some uranium-containing glass does not fluoresce under ultraviolet light, e.

The presence of uranium glass objects in museum and private collections has raised radiation protection concerns resulting from possible exposure to ionizing.
This is a special type of dating method that makes use of a microscope rather than a mass spectrometer and capitalizes on damaged zones, or tracks, created in crystals during the spontaneous fission of uranium In this unique type of radioactive decay , the nucleus of a single parent uranium atom splits into two fragments of similar mass with such force that a trail of crystal damage is left in the mineral. Immersing the sample in an etching solution of strong acid or base enlarges the fission tracks into tube-shaped holes large enough to be seen under a high-powered microscope.
The number of tracks present can be used to calculate the age of the sample if the uranium content is known. Fortunately, the uranium content of precisely the spot under scrutiny can be obtained by a similar process when working with a polished crystal surface. The sample is bombarded with slow thermal neutrons in a nuclear reactor , resulting in induced fission of uranium as opposed to spontaneous fission of uranium The fission tracks produced by this process are recorded by a thin plastic film placed against the surface of the sample.
The uranium content of the material can then be calculated so long as the neutron dose is known. The preservation of crystal damage i.
