Zimax glass cylinder vases: This collection offers you more than 15 different sizes of glass cylinder vases, which can be used for any occasion. We have glass cylinder vases from 4.5” to 26” tall and 4” to 8” opening. Maybe you are looking for small sizes to use them as candleholders or large sizes for centerpieces. The most common size is 6” opening with different heights. Our glass cylinder vases are packed in cardboard boxes with inner boxes, which are safer and easer for storage.

 The art of glass-making as we know it today came into its own with the introduction of a new implement which revolutionized the manufacturing technique: the blowpipe. With blowing it became possible to create objects of lightness and transparency such as had never been seen before. This discovery is generally thought to date from the beginning of the Christian time and its place of origin is believed to have been Syria. The composition of the vitreous material is based on a mineral substance (silica) alloyed with an alkali (soda), which serves as a founding medium. At a high temperature an amorphous material is obtained which assumes a brilliant red color; in this soft pasty state it can be blown, stamped, used to weld two other pieces together, drawn into fine threads, or poured into moulds, cut with scissors, and modeled ad libitum, until it cool down. The cooling must, however, proceed by stages, so as to avoid upsetting the stability of molecular cohesion, which might easily result in breakage. For this reason the objects are removed to successive cooling chambers until they are adjusted to the surrounding temperature. The glass may be colorless or appropriately tinted in its actual substance by the addition of particular chemicals, generally metallic oxides, with which it is possible to obtain the most varied hues, ranging from bright red to blue, green, milky white, and so on (a technique already known to glass-makers of the 1st century). Transparency, on the other hand, is obtained by purifying the material of scoria by means of appropriate substances. The glassmakers used manganese dioxide, the Bohemians and the British employed strong admixture of lead and potassium oxides for their crystal. The glass cylinder vases can be ornamented when the glass is cold, either without first reheating it, or else in such a way that the color is vitrified in its turn. The latter method produces a true enamel painting, characteristic of certain oriental (Syrian) and Venetian decorative techniques.

 Glass is therefore an amorphous material, but unlike pottery, cannot be molded until it is incandescent. Melting takes place in special furnaces, generally circular in shape and provided with several external openings or ‘ working holes’; behind each working hole the compounds are melted in large pots at a very high temperature (2000-2500 C.).  From these pots the master glass blower takes on the end of his pipe a small amount of glass, called the bolo, in a fluid and slightly viscous state. Then he blows into the pipe and adds the finishing touches with the aid of a very few simple tools. This method has remained virtually unchanged since the invention of the blowpipe, which still represents the chief implement in the art of glass making. Likewise, the other tools, perfect in their simplicity, have remained much the same throughout the centuries.
