Re: use of Phlorogucinol and Lycopodium
We place several spoons of plain flour in a petri dish inside the can. Make sure the hose you blow through is resting in the petri dish so you you can easily make a flour cloud inside the tin when you give it a good huff. The height of candle is not so important but I wouldn't make it too tall...Hop...

Re: Nitrates
I always keep saying I'm going to measure out 1M quantities to store in jars. Then if they turn to liquid you still know the quantity will make up 1M. But of course it's on my "round tuit list"!

Re: Splints?
Hi,
I used to use paddle pop sticks which I cut to thinner strips (which was annoying because they didn't split evenly) but now I use wooden skewers. I cut the skewers in half in most cases and they last for a long time.
