A cross over category: Amethyst glass is any of the many glasswares made in the dark purple color of the gemstone called amethyst. Included in this category are any pieces made amethyst. Very dark pieces called 'black amethyst' should be listed under this heading.

For this section we will leave it up to you - if you can not find another section to list your item in. We say antique, but old maybe used - let said before the 1980s. Here could be pieces made in other parts of world not listed below. Such as Germany, Bohemian, Czech, British, French, Italian, North American, Scandinavian. While not being over a hundred years old, the kids next door (under 10) think I am old - So if you think your item will fit - use it.

While China, Japan, Korea, and even Mid-Eastern pieces are made of something other than 'glass', we listed this.

Carnival glass is an inexpensive 'pressed glass', made as both functional and ornamental objects Always iridescent and found in a wide spectrum of colors. Produced in the United States, Britain, and several European and Asian countries from the early 1900s until the present. Carnival glass gets its iridescent sheen from the application of metallic salts while the glass is still hot from the pressing then re-firing the glass. Glass workers sometimes refer to carnival glass as "dope glass" because the process of applying the iridescent coloring to the surface is called "doping".

Cobalt glass is a deep blue colored glass Prepared by adding cobalt compounds to the molten glass. It is appreciated for its attractive color Also used as an optical filter in flame tests to filter out the yellow flame caused by the contamination of sodium.

More or less any thing made today

Also known as CRAQUELLE GLASS, ICE GLASS, OVERSHOT GLASS It was the Venetian Glass Makers of the 16th Century, who invented this marvelous process, still used today. The glass was immersed in cold water while it was molten hot, thereby cracking the glass Then reheated and either mold or hand blown into the shape the glass blower desired The reheating of the glass sealed the cracks If you run your hands over CRACKLE GLASS, you can feel the cracks, but the inside is smooth to touch.

Glass ornamented with patterns cut into its surface by an abrasive wheel and polished. Could be Crystal or not.

Lead crystal, (also called crystal), is lead glass that has been hand or machine cut with facets. Lead oxide added to the molten glass gives lead crystal a much higher index of refraction than normal glass, and consequently much greater "sparkle". The presence of lead also makes the glass softer and easier to cut. Crystal can consist of up to 33% lead, at which point it has the most sparkle. The higher lead content also makes it much more difficult to form crystal during blowing. Englishman George Ravenscroft discovered crystal in 1676.(source: http://en.wikipedia.org/) Could be cut glass or not.

Clear or colored/tinted translucent glassware machine-produced during the 1930s Most of this glassware was made in the central and mid-west United States, where access to raw materials and power made manufacturing inexpensive in the first half of the twentieth century. More than twenty manufacturers made more than 100 patterns, and entire dinner sets were made in some patterns. Common colors are clear, or crystal; pink, pale blue, green, and amber. Less common colors include yellow, jadeite (opaque pale green), delphite (opaque pale blue), cobalt blue, red, black, and white.

Pattern Glass, also referred to as Pressed Glass, was produced between 1850 to 1910. Originally designed for everyday use and was made to be very durable and at the same time, attractive. Patterns ranged from very plain to very elaborate cut glass imitations. The market tried and tested each pattern. Even patterns with Animals, Fruits and Florals were designed and created, with attention to fine details. Some of the patterns were produced as full table settings, while others were produced only in goblet form or single tableware pieces. People originally bought goblets and tableware for their beauty and artistic design. In addition, it was functional and affordable.
|
Elegant glassware, including patterns made by Fostoria, Heisey, Cambridge, Duncan and Miller, Tiffin and others. While not a 'glass person' we attempted to give you sections that fit your needs - many of these area cross over. It is one of those cross over.

Here is another area that is a cross over, not just bowls, etc but Depression Glass as well.

Opalescence is a type of dichroism (the property of exhibiting different colors by reflected or transmitted light) seen in highly dispersed systems with little opacity. The material appears yellowish-red in transmitted light and blue in the scattered light perpendicular to the transmitted light. The phenomenon is named after the appearance of opals There are different degrees of opalescent behaviour. One can still see through a slightly opalescent phase. The more particles and the bigger the particles are, the stronger the scattering arising from them and the cloudier the particular phase will look. At a certain concentration the scattering is so strong that all light passing through is scattered, so that it is not transparent any more. Examples are the blue sky in the daytime and the yellowish-red sky at sunset. Another example can be made by adding a few droplets of milk to a glass of water: the milk looks bluish. If one looks through the milk at a light source, it looks yellowish-red.

Pressed glass (also Pattern Glass) is a form of glass made using a plunger to press molten glass into mold. It was first patented by American inventor John P. Bakewell in 1825 to make knobs for furniture. One type of pressed glass is 'carnival glass - the method is also used to make beads

PYREX is a trade-mark (1915) for products manufactured and sold by Corning Glass Works. Originally borosilicate glass. Borosilicate glass is a type of heat-resistant glass. Borosilicate glass was first developed by German glassmaker Otto Schott in the late 19th century and sold under the brand name "Duran" in 1893. Holophane manufactures original equipment lenses for street lights under the Endural brand name. Bomex is a brand of borosilicate glassware made in China for a number of resellers in the United States and abroad.

Another cross over: Ruby is a red gemstone that varies from a light pink to a blood red, a variety of the mineral corundum (aluminium oxide). The color is caused mainly by chromium. Its name comes from ruber, Latin for red. Other varieties of gem-quality corundum are called sapphires. It is considered one of the four precious stones, together with the sapphire, the emerald and the diamond.

Stretch glass was made by a number of American glass factories from about 1916 to the early 1930's. It was either pressed or blown into molds. When the piece of glass was still hot from the mold - it was sprayed with metallic salts to give the surface iridescence. It was then reheated and "worked"in some way (flared out, cupped in or crimped, etc.). The working of the glass "stretched" the iridescent surface and produced an "onion skin" effect. Some pieces of stretch glass will have very obvious "stretchmarks". Other pieces that have not been worked as much will have very fine "stretchmarks". Stretch glass differs from carnival glass in two distinct ways. Carnival glass was "worked" first and then iridized - and carnival glass was heavily patterned while stretch glass has little or no pattern. (source: http://stretchglasssociety.org/)

A particular color of yellow-green glass that is made by adding 2% Uranium Dioxide to the ingredients when the glass formula is made. The addition of the Uranium Dioxide makes the glass color yellow-green. Vaseline Glass is verifiable by using an ultraviolet light (blacklight) on the glass item. When done, the glass turns a bright florescent 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. Not all yellow-green glass will turn florescent GREEN when a UV light is shined on it. When manganese is added to the glass formula (which also makes a yellow-colored glass) instead of Uranium Dioxide, for instance, the end product will glow under a black light, but the color is an orange/peach color OR a lime green color that is much fainter than the bright neon green under UV light. Manganese was added to the glass mixture to counteract the minor traces of iron that would give the glass a 'coke-bottle' greenish tint to it. (source: http://www.vaselineglass.org/)
