candle

The invention relates to candles and in particular to decorative candles with flame colorants, such as strontium, copper, barium, lithium,

Sodium and potassium and their compounds, perfumes or aromatic substances and wax dyes, such as ultramarine,

Chromium oxide, cadmium sulfide, cobalt blue and English red.

Serköaaliche Kersen, especially those with additives of the type mentioned above , generally do not burn with a steady flame, but run-off often occurs. This instability of the flame is at least partly due to the fact that the candle contains incombustible and hardly combustible substances that adhere to the wick and prevent it from burning evenly and completely . Furthermore, such deposits of incombustible substances on the wick promote the sucking up of molten wax in the wick by capillary action, as a result of which the combustion of the wick is further impaired and which leads to the formation of smoke and

H67525

for the candle to drain.

These disadvantages are avoided with the candle according to the invention or reduced, in which the incombustible or hardly combustible substances are removed when the wick burns.

■ According to the invention, the candle body and / or the wick contains the Candle a cutting agent that when the candle is lit, a melted one on the burning part of the wick Forms material whose boiling point is above the temperature of the flame.

The molten material that forms on the wick adsorbs or dissolves non-combustible or non-combustible substances that dissolve otherwise as solids were deposited and would cause the mentioned run-off and puffing «

^ When the candle burns down, the tip of the wick curls up, see above that it protrudes from the flame and the molten material solidifies and falls due to its own weight together with the adsorbed or dissolved substances and the remains of the burnt Wicks off.

By the inventive addition of a cosolvent, the flame of the burning candle is stabilized even if the K _e contains rze interfering colorants, or other additives of the aforementioned type.

The extender is preferably a material which is on
burning wick results in a substance whose melting point is between 200 and 800 C and whose boiling point is at least
1200 ° C.

The extender can be an oxide which can be reduced to a metal on the burning wick, which at the temperature of the
burning wick is molten. Oxides suitable for the purpose according to the invention are the oxides of tin, bismuth, thallium, cadmium, lead, zinc, tellurium, arsenic and antimony. The reduction of the oxide on the burning wick contributes to the oxidation of the wick,
to destroy its fiber structure and to promote its complete combustion.

JSs can also use other metal compounds provided that they yield the molten metal on the burning wick. Such connections preferably also assist immediately the burning of the wick, as described.

Optionally, low-melting metals themselves can be incorporated into the candle, for which purpose the metals given above are suitable. In some cases it appears that upon initial contact with the base of the flame, the metal will
burning candle is oxidized, but the oxide is then, as mentioned, reduced back to the molten metal at the wick.

The abovementioned diluents can be used individually or mixed,

can be used, for example, in the form of alloys.

In the following the invention is given with reference to the Examples are described in more detail in connection with the accompanying drawing and show:

. 1 is a schematic view, partly in section, of a candle according to the invention shortly after the wick has burned has been brought;

Fig. 2 is a similar view of the candle showing a burned out Wick shows and

Fig. 3 shows the candle of Fig. 2 shortly after the tip of the wick has fallen off.

In Fig. 1, a candle is shown with a wick 12 made of cotton yarn, which is surrounded by a guard body 11, which with impregnated with an extender. The exposed sin 17 of the wick burns with a flame 13, which is the tip l * f dee Wicks UKhUlIt. If the flame keeps burning the wick down, the exposed sine 17 of the wick curls until finally * the tip of which protrudes beyond the boundary 16 of the flame to the outside, as shown in FIG. Part 15 of the The wick falls outside the flame 13 by its own weight and, as shown in FIG. 3, falls down.

In the following examples, the same applies to those given ! Parts and prosecution by parts by weight and percent by weight.

example 1

The after-body 1 of the candle has the following composition:

Paraffin 80 %

Stearic acid 8 % Red lead (Pb ₃ O ₁ ^) 2 % (all solvents)

Copper nitrate (Cu (NO> ₂ > Io % (all flame dyes) cobalt blue a small amount (as a guard

dye)

When the wick 12 is first lit (Fig. 1) it will burn incomplete with a relatively low temperature. • (en η je do eh the Dooht the part of the higher temperature of the flame, i.e. the kisser flame (Figs. 2 and 3) »has reached and that Red lead destroys the fiber structure of the wick, it gets through the incomplete combustion of the wick oxidizes the carbon produced1

Pe ₃ O ₄ ♦ 2C -— 3Pb + 2CO ₂

The Bi'i produced by this reduction is also in the melt flow so that, since its melting point is 327 ° C, dissolves or ad-

sorbed, which otherwise impair the burning of the wick became. When the wick is curled, its tip protrudes from the out «so that the lead in this part solidifies and is through Dead weight falls off together with the non-fibrous residue of the wick.

The incombustible components of the candle are therefore when it burns down the wick is constantly removed and a steady flame is maintained.

Example 2

■ The ^M axle beam 11, the composition has:

Paraffin 6o %

hardened 01 16 %

Antimony oxychloride (SbOCl) 1 % (as extender)

Barium chlorate (Ba (ClO ₃ ) _£ ) 13 % (as flan dye)

Potassium chlorate 1 % (as an oxidizing agent)

Chromium oxide (Cr ^ O.-) a small amount (as # acha-

dye)

In this case the antimony oxychloride acts as an oxidizing agent sur promoting the burning of the wick:

2SbOCl + C 2Sb + CO ₂ +

and if it is reduced to molten antimony (melting point 630 ⁰ C)

welohes in the same way "ie the molten lead in Example 1 works.

Potassium chlorate provides the oxygen to promote the combustion of dyes and the like.

. Example 3

The specialist body 11 has the following composition:

Paraffin 42 %

hydrogenated oil ko%

Thallium perchlorate

(TlClO ₂ J 3 5 <6 (as a solvent)

Nat ri urn hlori d

(NaCl) 15 % (as flame dye)

Cadmium sulfide in small amounts (all wax coloring agents)

Thallium perchlorate contributes to the burning of the wick and destroys its fiber structure:

+ 2C - 2Tl + 2CO ₂

and results in thallium in the armpit (melting point 3o3 C)

example

The guard body 11 has the composition:

Paraffin stearic acid cadmium (powder)

Nickel chloride (NiCl ₂ )

Cobalt blue (CoCAl ₂ O)

80 %

8 %

3 % (as blending agent)

9 % (as flame dye)

a small amount (as a specialist dye)

In this case, the extender is cadmium metal, which is oxidized to oxide in the lower part of the flame, so that in a similar way to the above- described extender cadmium results in molten cadmium:

2CdO

2Cd CO,

example

The wax body 11 has the composition:

Paraffin hardened oil

Alloy au * Sn (80 %) and Pb (2o *) powder)

fltrontium carbonate (SrCO ₃ )

Red lead ^ 3 % ko%

The tin / lead alloy behaves in a similar way to that Cadmium in the previous example and becomes one first Oxydgemiach oxidized:

2 Pb + O ₂ 2PbO

2Sn + O ₂ 2SnO

which is then reduced again to a molten Sn / Pb alloy will.
