what chemicals are used to colour the smoke after the conclave?

umm. iknow this one..can't think...they use little sulfur tablest to make white?  and straw to make black?  right?

If I remember correctly, it gives off a yellowish violet color when heated in a flame.

AgNO3 + NaCl => AgCl(white ppt) + NaNO3\nAgNO3 + KI => AgI( yellow ppt) + KNO3\n\nthere is a change of color because AgI is produced

The colour of smokey quartz in nature is caused by the effect of background radiation from the surrounding rocks. The system of colour production is complex and involves the removal of an electron from a normally occupied site. This colouration can be induced into clear quartz by bombardment in a Cobalt 60 gamma-irradiation unit. It will turn a deep smokey colour in about half an hour and reach maximum colour in less than a day. This type of smokey colouration is sensitive to heat and heat treatment is often used to modify the basic colour to other lighter shades.

If you trust yourself not to burn the place down, you could light some candles. The flame will burn the carbon particles in the smoke and make it clear up quicker.

If you mean foam as a suppression agent, they are usually protien or soap based.  When mixed with water they create the "foam" that can used to blanket a fire, particularly when flammable liquids are involved and water alone would simply spread the fire becuase most flammable liquids float on water.

If it were possible to extract the heat, it would self-extinguish and cease to be a flame. You can have an invisible flame with no colour, if I remember rightly, burning pure alcohol produces this.

some have a bleaching agent in

Nitrate it. Treat it with H2SO4 and HNO3. Simply warm it.

flammable , orderless, colorless . have low frozen point ,reactive

pass a lighter or a match near to it, the smoke will make it look old, I tried that for a History assignment it looked cool =)

In chemical qualitive analysis, this is known as a flame test.  Many metals (and some non-metals) have distinctive colors.\n\nThe heat of the flame excites one or more electrons of the metal atom causing it to go to a higher energy state.  When the electron returns to the "ground state" electromagnetic energy is released and this appears as light of a specific color.

The official ingredients in 'fog juice' are glycol and water, although I've heard of people using liquid paraffin wax.  The glycol/water mixture is turned into a mist inside the fog machine, and then forced over a heating element.  It overheats and becomes a non-toxic smoke.  You don't want to be standing within a foot of the nozzle, however, because some of the glycol mixture comes out as a very hot spray, not smoke.

Food colouring and bleach.

Put the lighted end of a glowing splinter into a test tube containing the subject gas. If it burns or bursts into flames, you have oxygen in there. But if the splinter makes a pop, you have hydrogen instead. If it is extinguished, you got carbon dioxide

A rapid, persistent chemical change that releases heat and light and is accompanied by flame, especially the exothermic oxidation of a combustible substance.\nAn oxidising reaction takes place which gives off light and heat to form a flame. The burning process converts oxygen and other substances into a mixture of gases, water vapour and small solid particles which we call smoke. The gases are mostly carbon dioxide - C02 and carbon monoxide - CO.\nThe smoke particles, or soot, are mostly unburned carbon (C). If you hold a polished metal spoon above a candle flame it will become stained with soot. Smoke contains water vapour which is produced when the hydrogen from the candle wax combines with oxygen in the air.

nope!  pine tar is clear..however... it's very sticky so any dust, blood or smoke is likely to adhear to it causing it to color.
