i'm not exactly sure, but i would think that it would depend on the soil composition.  after all a fine clay has much different properties than a sandy or rocky soil

OK, here goes---no chemical formulas--look that up in your chemistry book.\n\nLead is mined.  The ore comes out of the mine as a Lead Oxide.  Chunks of ore range from about the size of a loaf of bread on down.  Ore goes through jaw crushers to reduce in size.  Golfball size ore goes through a rod mill. (Large revolving drum full of steel rods)  Comes out pea sized.  Ore goes into a ball mill. (Large revolving drum full of steel balls)  Comes out the size and consistency of talcum powder)   The ore/water mixture is called a slurry.  The slurry comes out of the ball mill and goes into flotation chambers where a mixture of water and foaming agents are being agitated.  The lead particles in the slurry attach themselves to the bubbles created by the foaming agent.  They rise to the top of the tank where the foam is scraped off by paddles.  Waste rock called tailings is pumped in a slurry form to a disposal site.  The lead bubble foam is transported to a dryer.  The dryer removes excess water and leaves the final product of the mine and mill--lead concentrate.  (lead oxide)\n\nThe concentrate is hauled to the smelter.  If it was put into the furnace in its current state it would go right up the chimney---the lead is the consistency of talcum powder.  In order to melt the lead, we have to hold it in place long enough to melt so that it doesn't all just blow out the chimney.  This is done by a process called sintering.  Lead concentrate is added to crushed limestone, coke and other chemical reagents.  It is then run through the sintering machine.  The sintering machine roasts the mixture for 20 minutes and when the sinter comes out the end of the machine it resembles the klinkers that you'll see come out of an old coal fired furnace.  The roasting process causes all the ingredients to mold together into a solid chunk---called sinter.  The sinter comes out of the machine in huge chunks---as big as a car---and is run through a crusher to break it up into manageable size--about the size of a basketball on down.  The sinter goes into a storage bin.\n\nNow, its time for the furnace.  The sinter is mixed with more powdered limestone, iron ore, coke, coke breeze, lead scraps from spills.  This mixture is fed into a top feed furnace.  As the mixture falls down into the bottom of the furnace it encounters the fire.  Pure oxygen is pumped into the furnace, feeding the fire.  The coke and coke breeze burn creating enormous amounts of heat.  The sinter holds the lead in place long enough for it to melt and flow into the bottom of the furnace.  The sinter is then consumed by the fire as its remaining ingredients are partially cooked coke.  When the bottom of the furnace fills up with molten lead, it is tapped by the furnaceman.  The furnaceman will drain off a huge kettle full of molten lead.  Once the kettle is full the furnaceman will shut off the flow.  An overhead crane picks up the kettle and takes it over to the refinery area.\n\nA lot of sulfur containing compounds are generated as by-products of the smelting process.  At one plant I worked at they had an acid plant on site.  By scrubbing the furnace's exhaust gasses, they removed most of the SO2 from the exhaust.  The SO2 was then sent to the acid plant where a chemical reaction took place and the SO2 was changed to sulfuric acid---H2SO4.  The acid plant would produce a rail car full of 98% pure sufuric acid every day.\n\nThe scrubbed exhaust gasses went into another scrubbing device called the 'baghouse'.  This was a huge four story building about the size of a city block.  Every floor had dozens of rooms on it.  Each room was filled with bags that stretched from the ceiling of the room to the floor.  This bags were made of cloth---they were filter bags.  The exhaust gasses passed through these bags and the most minute particles were filtered out. The remaining exhaust gasses went up the chimney.\n\nWhoa--that brought back memories!  Believe me, you haven't lived t

Porcelain is a hard ceramic material. It is fired at a higher temperature than that used to fire glazed earthenware and stoneware pottery. It is white or off-white in colour, translucent and can be decorated to provide additional colour. Porcelain is made by firing a mixture of materials including China clay and China stone in a kiln at temperatures in the region of 1200 to 1350 degrees Celsius. The resulting material is hard, strong, glassy and durable, but also brittle. The main components of porcelain, China clay (kaolinite) and crushed China stone (a form of feldspar) are found in nature and result from the weathering and decomposition of igneous rocks such as granite and basalt.\n\nClays used for the manufacture of porcelain can be specially formulated to provide high-strength and high-durability. It is also possible to blend clays to obtain a clay body that is ideal for throwing on a potter's wheel. A wide range of porcelain clays is readily available from many specialist suppliers of materials for ceramics.

Never trust materials science majors ...\n\n1. NaCl (s) --> Na+ (aq) + Cl- (aq)\n2. Ca (s) + 2H2O (l) --> Ca(OH)2 (s) + H2 (g)\n3. Ca(OH)2 (s) --> H2O (g) + CaO (s)

My first instinct is to say clay. It has all the right ingredients.

I think this guy is talking about bentonite.  It's an expanding, ultra-low permeability clay that comes in pellets or chips (dry, of course).  We use it in the environmental business to seal between groundwater layers.

Let's give the variable to the brick's parameters.\n\n1) W = width of brick\n2) L = length of the brick\n3) H = height or thickness of the brick\n\n   As you already know, brick has six faces.  In this way, we can calculate the surface by\n\n     Surface of brick = (2 * (W * L)) + (2 * (W * H)) + (2 * (L * H))\n\nNote:  Be careful with the unit.  You should have cubic centimeter or cubic of whatever unit the brick is measured by.\n\nAlso, try Math.com for other equations that you are looking for.  Or www.wikipedia.org and type in volume measure or volume formula in the search box.

there are different formulas for volume.

The empirical formula is derived from the mineral's structural (molecular) formula by using the published analysis of the mineral or deriving the analysis using basic rules.\nAtomic substitutions were analyzed by the following procedure if published analyses were not available. Adjustments were made to match the measured density with the calculated density if needed: \n(K,Na) = K0.75 Na0.25\n\n(K,Na,Cs)= K0.6 Na0.3 Cs0.1 \n\nRare Earth Elements (REE in formulae) were calculated based on the chondrite normalized abundances. This analysis used 144 for the REE atomic weight and 61 as the atomic number. \nSolid solution series minerals were calculated based on the mid-points of the accepted compositional range of the mineral..☺

Montmorillonite's water content is variable and it increases greatly in volume when it absorbs water. Chemically it is hydrated sodium calcium aluminium magnesium silicate hydroxide (Na,Ca)x(Al,Mg)2(Si4O10)(OH)2·nH2O. Potassium, iron, and other cations are common substitutes, the exact ratio of cations varies with source.\n\nI would assume it could be magnetic, but not always. As for the affect/reaction I didnt find any information either way.
