Which one of these samples weighs more, the raw lump form of the clay or after it has been ground into a powder? Wrong. It is the lumps. Even though there is all that empty air space between those lumps, there is even more air spaces in the powder. The top one weighs 1662 grams (there is a 500g counter-weight barely visible), the bottom one is 1255. The finer I grind it the lighter it will be. If I were to fill in all the voids between the lumps on the top one with smaller sized lumps I could get alot more weight yet! It works the same on the ultimate particle level, when we combine powders of varying particle sizes we get a more dense and stronger dried product.
