burning powdered incense is different than burning resin incenses, which one burns in portions upon charcoal disks. each Lucky Mojo formula powder contains saltpeter, which is a natural combustible that keeps it burning after it is lit (that's why it is called 'self-lighting', because it keeps itself lit over time). if one burns such a powder on charcoal (try it sometime if you're curious, i have and it was kind of interesting), it combusts extremely quickly and almost evaporates without leaving any scent whatsoever (a waste of both charcoal and incense powder).
the trick is to get the powder into a form that will allow it to be lit easily and to burn properly. the conventional method for burning powdered incense is to shape it as a cone. this is described by catherine and illustrated with photographss by Carin Huber at:
http://herb-magic.com/incense-powder-cones.htmlbriefly, one makes a cone shape by using a piece of paper turned upon itself. typically this is done in small size, comparable to the size that cone incense is sold by mass-manufacturers. packing the cone, the incense naturally clings to itself as one sets the cone upon a metal, stone, or other non-flammable surface where it is to burn. one may then light it with a match, and it should burn naturally away.
CAUTION: I have occasionally placed cones upon the end of my cheap wooden stick incense holder, and this eventually did set the holder itself aflame (additionally setting the altar to smolder!). this is why there are metal bases provided with many cones that are sold in packaging -- whatever they are set upon will be exposed to burning embers and should therefore be capable of holding them).
in terms of their size and shape, i don't know why one could not make a larger size for extravagant events (i'll test this someday soon with a medium size and see if there are burning problems), or make them into some other stable, essentially vertical shape for which one has a form. one's limitations here would depend on how well the powder cleaves to itself, since in a cone it forms a little pile, whereas other shapes may fray about the edges or collapse away due to the effects of gravity.
since these cones burn completely through, theoretically (test it and get back to us!) they might be placed aside one another and burned in sequence, even with different formulae powders (effecting, for example, a 'reversible' effect by burning an Uncrossing Powder cone and then some pro-active cone such as Blessing, Attraction, or Destruction Powder).
I can imagine a constructed vertical stand in which the bottom of one cone sets upon a disk with a hole allowing the protrusion of the next one below it so as to set up a multi-cone burn quite elegantly, but i have never seen such a contraption. most people just light them individually as they need them.
enjoy!
