So I need some rocks, minerals, most minerals are very expensive i want knownw the cheap minerals, please.Minerals likeHaliteFluoriteCalciteOrthoclaseQuartzAsbestosPlease minerals like these but cheap onesI need about 9, the cheapest heres a list to get you statedtalcapatitetopazcorundumbiolitelimonitedolomitegraphitehematitesulfurkaolite
all of the ones you listed are cheap. so whats left to ask. you listed all i would have.
if you used a raised box with fire in it ie; a stove burner you would increase the output 3x beacause the heat is retained but the sides if the stove heat the room by thermal airflow for example cold air is sucked under and around and returns to room hot from higher up which acts almost as a radiator would so not as much fuel is needed. also tiles to reflect heat would help.
It only really helps if you have a fan that blows the hot air back into the room, otherwise most of the heat from the fireplace, and the room, head up the chimney in the updraft.
I'm not sure your motive for asking this question, but I think you should know that Asbestos cause cancer, and is a toxic material. Lol, be careful, whatever your doing. Unless your just making a list, in that case I'm of no help. Sorry.
If you look in your yellow pages phone book under minerals, rock crushing, quartz, talc, kaolite, granite, marble,iron smelters; you will find companies that deal in these minerals on a commercial basis. Phone them up individually, Tell them your name and ask if they could send you specimen pieces for a mineral rock collection that you are personally building in relation to school studies. If you live in an area of sedimentary rock outcrops, you will probably find limonite on top of those rocks, a rusty looking yellow, almost clay-like mass. you could also ask the curator of minerals of the geology department of yur local university if they would have any pieces of rock forming minerals and commercial miners that you might have for free. Do the same to the curator of minerals at your local museum. Have fun.
