making charcoal
Bookmarked 526 weeks ago
i made a batch of charcoal using the mound method then stored it in baskets for later use charcoal is a fuel that burns hotter than the wood it039s made from this is because the initial energy consuming steps of combustion have taken place while making the charcoal driving off the volatile components of the wood such as water and sap the result is a nearly pure carbon fuel that burns hotter than wood without smoke and with less flame charcoal was primarily a metallurgical fuel in ancient times but was sometimes used for cooking too to make the charcoal the wood was broken up and stacked in to a mound with the largest pieces in the center and smaller sticks and leaves on the out side the mound was coated in mud and a hole was left in the top while 8 smaller air holes were made around the base of the mound a fire was kindled in the top of the mound using hot coals from the fire and the burning process beganthe fire burned down the inside of the mound against the updraft i reason that this is a better way to make charcoal as the rising flames have used up the oxygen and prevent the charcoal already made above them from burning while driving out even more volatiles i watched the air holes at the base of the mound and when the fire had burned right up to each opening i plugged them with mud once all 8 holes had be sealed the hole in the top of the mound was sealed with mud and the mound left to coolthe next day when the mound was cool to the touch this can take about 2 days sometimes i opened the mound the resulting charcoal was good quality some wood near the air entries had burned to ash though these were only small twigs and leaves this is the reason small brush is put on the out side of the mound to be burned preferentially to the larger wood on the inside thus protecting the large pieces of charcoalthe charcoal that was made was hard and shiny when broken open it had the ray structure of the wood preserved when moving the hand through it the charcoal sounded tinny like coral on a beach being moved by waves these are signs of good quality bad charcoal is soft breaks easily and has a muffled sound i intend to use the charcoal to produce hotter fires than i039m able to with wood alone from my research a natural draft furnace using wood a kiln can reach a maximum of 1400 c degrees whereas a natural draft furnace using charcoal can reach 1600 c degrees achieving high temperatures is necessary for changing material to obtain better technology eg smelting ore into metal

how to understand the image of a black hole

we are about to see the first image of a black hole the supermassive black hole sagittarius a at the center of the milky way galaxy or maybe the supermassive black hole in the galaxy m87 but what is that image really showing usthis is an awesome paper on the topic by jp luminet:image of a spherical black hole with thin accretion diskastronomy and astrophysics vol 75 no 1-2 may 1979 p 228-235https:ve42columinetusing my every day intuition i wondered: will we see the quotshadowquot of the black hole even if we039re looking edge on at the accretion disk the answer is yes because the black hole warps space-time so even if we wouldn039t normally be able to see the back of the accretion disk we can in this case because its light is bent up and over the black hole similarly we can see light from the bottom of the back of the accretion disk because it039s bent under the bottom of the black hole plus there are additional images from light that does a half turn around the black
