Hello BrightStar,
thanks for the advice.
When I told incense burning charcoal tablet I thought the charcoal tablet on which is placed incense when it gets hot.
Incense is melted on the tablet and drop a specific smell. So, I want to make a tablet compose charcoal powder, potassium nitrate, binder etc. Then I compresses mass in the press so I got a solid tablet. Will potassium nitrate to make the pills for a short time incandesced, of course when the fire?
Best regards

Charcoal and nitrate will be a form of explosive (Black Powder!) in some forms this will simply explode, in other forms it will burn more safely. Can you find the chemical analysis of an existing slow burn pellet? The you would have the chemistry sorted, The physical aspects -particle size and pressing force need to be considered too.

incense sticks give off sufficient carbon monoxide to rapidly trigger a co alarm most aromatic oils are inflammable so they could not be vaporised and dispersed wihout ignition occuring .A more energetic incense dispersal without ignition risk or high co levels and without other gaseous combustion products presents quite a challenge

Dear Pyro-Friends:

You want to make incense and not powder.
I think it's the wrong way to put in any oxidizer: neither chlorates nor nitrates, for they accelerate burning rate, but do not necessarily make the burning more stable.

Put in a burning catalist: not antimony, for vapors may be toxic, but finest copper powder, Copper Oxide (CuO) or Copper Carbonate (heating up, during burning, also transforms it into CuO, but it is easier to mix in). You binder might be Dextrine (burns well), not Arabic Gum (does not burn as well and is quite hygroscopic).

Small (we're talking of the order of a few %) amounts of KNO3 in charcoal or other carbonaceous material can make something that burns slowly and DOESN'T explode, this is used in things like self lighting barbeque bricks, handwarmer sticks and packet ciggies, so should be OK for incense. The secret is to get the KNO3 evenly distributed, so you'll need a wet process.

Dear Toivo,
I want to make charcoal dust tablets. It serves to melt on it incense. My only dilemma is whether the KNO3 to give a relatively fast burning mass in which is inserted. Is potassium nitrate right choice? I have knowledge that the potassium nitrate element that gives the effect of burning compressed charcoal dust and binder.

Does this mean that the potassium nitrate right choice? I have knowledge that the potassium nitrate element that gives the effect of burning compressed charcoal dust with binders.
Previously, I thought it was sodium chlorate (NaClO3) or something different metal powder, but everything points to the potassium nitrate.
