| I have noticed that when I burn wood it leaves little ash but when I burn mostly tree bark, that it leaves a volume of ash that is about 5 times greater than wood. I have asked this question before with no answer. What is the element or chemical compound in tree bark versus tree wood that explains this difference. Is it potassium that the potassium compounds are metabolized into the bark.

| Yes, you always make a complete ash of yourself when you smoke that wacky wildwood weed, Archie!!!! Why don't you do an elemental astrological analysis of it using your continuum transfunctioner? Most likely it will be your very own element: halfassium!! <[Only registered users see links. ]> wrote in message news:1141584038.045314.210400@p10g2000cwp.googlegr oups.com... |

| At least we don't have marks on our knees like some crybaby who shall go unmentioned. If you want to be one of Archie's fool sycophants, that's your problem. Obviously, tree bark may be contaminated by soil and dirt particles from the environment. There is no hidden mystical meaning behind it.

| Soil and Dirt particles?! Is that a scientific analysis? Contaminated? Do you see many pure celulose trees? Ideally, you should get CO2 and H2O, but nothing's ideal. You don't get enough Oxygen to get such efficient burning, so, you get a lot of charcoal (near pure carbon), as well as lots of other stuff like nitrates and salts that are absorbed from the soil. We know this because ash used to be the main source of nitrates for the production of gunpowder way back when (and may still be, but I doubt it). Ash is not a known mixture, it just means what's left after burning. You could look at some analytical techniques ot detect levels of such nitrates and salts, which should be fairly straight forward, but I'm a chemoinformatician not an analyst.... Happy Ashin' Dan. P.S. Without your Post Script I doubt you would have received such a spurious answer to a very simple (no offence) question. |

| ahahaha... ahahahaha... Hey, yo!.. Farooq!.... ahahahaha... That is some kind of super Oak you've burnt there... along with some high class Ph.D. chemist doing his over-unit analysis: Eating this ash ought to be good for prostate problems (Zn) .... and great for/as an X-ray contrast medium (Ba & Sr). The Lead (Pb) might be a problem, however there appears to be sufficient P2O5 and SiO2 present to from very, very insoluble Pb-products. Still the enviro shits will declare this to a be a very toxic and hazardous substance... while levying and assessing you with permit charges, user fees and enviro surtaxes... even if you never make or sell any of this miraculous ash... and then the tree huggers will sue you for having burnt such a valuable and endangered plant which has sucked up and decontaminated so more than its possible share of toxic substances from the environment thru'/via its bio remediation.... ahahahahaha.. Thanks for the laughs, Farooq.... ahahahaha..... ahahaha... ahahahanson "Farooq W" <[Only registered users see links. ]> wrote in message news:1141653875.221484.242090@p10g2000cwp.googlegr oups.com...

| In article <1141653875.221484.242090@p10g2000cwp.googlegroups .com>, Farooq W <[Only registered users see links. ]> wrote: Yeah. The potassium nitrate for gunpowder came from under old manure piles. Potash was used for making soap, historically, since wood ash was more accessible than lye before industrial chmistry. This much is reasonable -- I'd expect high K and Ca, but the P and Si are a bit of a surprise. I suspect the Si came from the bracken, since some ferns (and notably the non-fern horsetail (Equisetum) concentrate silica, or perhaps it's from dirt. Maybe that explains the high P, too. While wood ash is an excellent source of K, it usually regarded as only a moderate source of P, for fertilizer. Non-woody material is higher in P, Mg and other elements important to plant nutrition. Not sure what Archaeometry is, but if it's analysis of ancient materials, the high silica may be due to infiltration from the soil, an early stage in fossilization. If these numbers come from the residue from an ancient forest fire, it would explain the higher levels of plant nutrients, since a lot of live green material would have been included. I suspect these are in ppt or more likely ppm, rather than %, or we'd be giving up mining in favor of forestry. The amounts of these trace elements probably vary a lot with the composition of the soil in which the plants grew. As for Mr. Plutonium, I can say from personal experience that yes, bark gives more ash than wood, because it contains more minerals than wood. Apparently trees don't pull as much good stuff out of bark cells as they die as they do from the cells that become wood. Note also that hardwood generally produces far more ash than softwood, at least for the North American temperate species I'm familiar with. "Tree" is a descriptive term, unrelated to phylogeny. Trees have evolved many times from different lineages, and conifer trees are unrelated to angiosperm trees. |

| Hi, As it happens, I have done quite a lot of analyses for the various bits of trees (particularly conifers). 14% silica is very high indeed for plant material (though not impossible- rice husks can be 20%). I have analysed bracken in the past for silica, and it would not make 14%. Equisetum just might, but you would need this to be most of the sample! I would think contamination or impregnation were both possible explanations. At least in conifers the bark and wood are generally lower in ash that the needles. In some species silica can be quite high in needles (e.g. spruce at 2% or more), and that can make up a substantial amount of the ash.

I did not see mercury on that list and since coal power stations are notorious for emitting mercury into the air, I wonder how much mercury is in bark of trees. But I know some tree species evolved into a fire resistant bark in order to live in fire prone regions, so I wonder what chemical it is that gives them the best fire resistance. Is it potassium and salts? Archimedes Plutonium [Only registered users see links. ] whole entire Universe is just one big atom where dots of the electron-dot-cloud are galaxies |
