Oh - lots of information here. Thank you everyone
I brought back some insence and charcoal from Lourdes last year but could not find a burner that I liked then [ those available seemed - how can i politely put it - New Age ?

] but have encountered a few problems, and solved some of them since.
For a burner I have a small almost triangular stainless steel dish which rests on a heat resistant mat and it is in front of an icon.
Charcoal has been a bit of a problem - my french stuff was wonderful - lit instantly but of course eventually the supply went done and I had to start looking for a local supplier - I assure you not easy. What I did find was expensive 10 pieces for about 2.33 US Dollars and it was very very hard to get it alight. Once lit it burned very quickly.
Now I have managed to find a good source - a ROCOR Monastery in England - wonderful incense [ a sample pack was 3 chunks of each of the 14 varieties

] and rolls of quick lighting charcoal [from Prinknash Abbey

] Now I have no problem , my charcoal lights easily , once the first contact area glows red I drop my piece of incense on and all is well
Still having problems finding wicks for my little vigil lamp though

That will be solved in time - next time I can get into Town I will take the 'wick holder' into a craft shop and see what I can find there. Till then a candle suffices [ I have little votive ones here and a lovely beeswax one for the caravan]
