Embodiment Construction

[0029]The present invention provides a composition having one or more flame colorant components and a drying agent. The flame colorant components are one or more inorganic metal salts. The flame colorant components are preferably selected from the group consisting of copper chloride, lithium chloride, copper sulphate, calcium chloride, potassium chloride, strontium chloride, sodium chloride and magnesium chloride. Each of these metal salts will produce a flame of a characteristic color when burned. The color corresponding to the flame produced by each salt is set out in the table below:

Abstract

A flame colorant composition, device and method incorporate inorganic metal salt particles as flame colorants, and a drying agent. The metal salts are preferably selected from among copper chloride, lithium chloride, copper sulphate, calcium chloride, potassium chloride, strontium chloride, sodium chloride and magnesium chloride, each producing a flame of a characteristic color. The drying agent is Micro-Cell E silica, prevents particle aggregation. Preferably, the components are similarly sized particles which do not exceed 0.16 centimeters (0.0625 inches) in diameter. There is also provided a dual layer envelope containing the flame colorant mixture, the inner layer a vapour barrier and the outer layer easily combustible. The device of the present invention will produce a colored flame lasting up to thirty minutes without additional components.

Description

FIELD OF THE INVENTION[0001]The present invention relates to flame colorant devices. In particular, the present invention relates to a flame colorant device incorporating a mixture of one or more inorganic metal salt colorants and a drying agent, as well as a method for producing the flame colorant device.BACKGROUND OF THE INVENTION[0002]It is known to provide devices and methods for flame coloration. For example, U.S. Patent Application Publication No. 2002 / 0148540 A1 to Hiskey et al. published on Oct. 17, 2002 relates to pyrotechnic compositions and, more particularly, to low-smoke producing pyrotechnic compositions which employ various metal salts as flame colorants.[0003]Metals are known to have an associated spectrum when burned. Hiskey teaches that among the metal salts that may be employed are sodium salts for the color orange-yellow, copper salts for the color blue, potassium salts for the color violet, and antimony salts for the color white. Further, combinations of metal s...
