Thanks Andrew excellent advice
I have just been making some more and it does seem to be a bit better.
Spread out on a piece of metal it is leaving behind a thousand or so tiny (0.25-0.5mm) balls of yellow sulphur and a black patch were it has burnt. I have not seen any red in the leftovers.
I measured the quantity quite accurately with some precision scales and put in 10 % sulphur I will try a bit less as it looks from the residue that there is too much.

I have a weeping willow in the garden so I am about to go and pull a few branches off
I have just been and looked closely at the charcoal that i ground up from forecourt lumpwood charcoal. Whilst most of it is a nice fine matt black powder it does seem to have thousands of small glittery shinny pieces in it. Almost similar to what a piece of coal looks like close up. I imagine this is not so good
especially as i put it in the mill last night and left it on untill this morning.

Just briefly could you let me know is there any tips on making the charcoal that i should know about?
I was planning to just put it in a biscuit tin with a hole in the lid and then place it on my gas bbq. With a few inspections every now and then until it looked pretty well blackened right through.

Thanks again for your excellent reply

thanks
I will give the gd sulphur a go, but i suspect it is going to be the same product

Haha oh well back to the books .How long do you mill your green mix for?.It may be your sulphur as i use lumpwood charcoal and get stupid fast BP (will post vid soon).Try a BP mix with out the sulphur and see if you get the same result

i mix it all for about three hours
Where do you get your sulphur from?
and if i try a mix without sulphur what will that do?
Can you recommend a book?

yes the sulphur looks like small reformed grey hemispheres about 5mm diameter when they are milled they do look a pale yellow colour its the same box as the garden direct sulphur chips that people have spoken about. So if you use the same potassium nitrate I guess it could be the sulphur. Any idea about the residue? I thought it should all go up in smoke

Thanks
So would the gd sulphur chips be the roll sulphur that I need to make the best black powder.
