Pneumonoultramicroscopicsilicovolcanoconiosis is "a lung disease caused by the inhalation of very fine silica dust found in volcanoes" and this dust sometimes can be found in lava rock and some sands from certain areas. It is "a special form of silicosis caused by ultra-microscopic particles of silica volcanic dust..."
Thanks Willlllllllllllll!!!!!!
But down here where I'm from (zone_5_illinois) we call it "silicosis of the lung" or "Sand Lung". We (in our area) do alot with the mining of the silica that everyone takes for granted day to day.
Now back to the rest of the story ( P.Harvey), when I mix any bulk soil amendments I usually have a mask on hand, so should anyone not knowing what they're concocting.
I personally use Turface, for simplicity reasons.
but thanks again for all the input from all,
I'll try some of your ideas too, (always looking for improvement)
