<p>The present invention relates mainly to the field of household chemistry, as well as to the arrangement of entertainments (performances of circus, theatre, etc.). The main point of the invention is selection and use of compounds, comprising flammable or inflammable substances with atoms of copper, barium, lithium, rubidium, strontium, thallium and/or other chemical elements, with colouring properties enough to see the colour, different from natural yellow-orange, with the naked eye in the conditions of natural flame in fire-place, candle, matches, torch, oil-lamp, etc. when an organic or inorganic firing materials (wood, coal, peat, candle paraffin, lamp-oil etc.) are burnt. The invention can be implemented by - immersion the firing material into the water solutions of salts of above mentioned elements, drying and subsequent insertion in flame so as to make coloured tongues of the flame, or - adding the above mentioned elements to the fire-retardant solution for matches treatment and /or to adding this salt to the mass for matches head, or - adding the above mentioned elements to the candle body substance (paraffin and/or other substances), or - usage the saturated solutions of compounds of above mentioned elements in polar, e.g., lower alcohols, or anpolar, e.g., higher crude oil fractions, organic solvents instead of usual lamp-oil or as additives to it.</p> |
