(Jaani kirik ja Toomkirik) Moving on, What is clay? (slide 4) Clay is fine-grained, firm earthy material that is plastic when wet and hardens when heated. Clay minerals are size of (point zero one mm)0,01mm. It is consisting primarily of hydrated silicates of aluminum and widely used in making bricks, tiles, and pottery. Clay minerals are typically formed over long periods of time by the gradual chemical weathering of rocks, by low concentrations of carbonic acid and other solvents. These solvents, usually acidic, migrate through the weathering rock after leaching through upper weathered layers. In addition to the weathering process, some clay minerals are formed by hydrothermal activity. Clay deposits may be formed in place as remainder deposits in soil, but thick deposits usually are formed as the result of a secondary sedimentary deposing process. Clay deposits are typically associated with very low energy depositional environments such as large lakes and marine basins. (slide 5)

About Dying Veneers I figured out that about 3 cups of solvent will give you about a foot of fluid height. The picture shown is curly maple. I used 3 cups of lacquer thinner, mixed with 10 parts Stewmac Cherry red, 10 parts Stewmac Vintage Amber, and 1 part Stewmac Black aniline dyes. Transtint liquid dyes can also be used. It only takes about 5 minutes of vacuum to fully impregnate most veneers with dye. I recommend using dyes with lacquer thinner or alcohol as these solvents will not warp the veneer and will dry very quickly. Something to remember... You can save the mixtures of dye in mason jars or any other solvent proof container if you want to use the same color again. If you're having trouble fitting a large length of veneer into the vessel, first wrap the veneer around a spare piece of 3" PVC, then slide the veneer and pvc into the vessel, push the veneer down onto the vessel's inner tube and remove the spare section of pipe .
these processes generally involve removing carbon from or adding hydrogen to the molecules, and using fluid catalytic cracking to convert the longer, more complex molecules in the oil to the shorter, simpler ones in the fuels. Due to its high energy density, easy transportability and relative abundance, oil has become the world's most important source of energy since the mid-1950s. Petroleum is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, and plastics; the 16 per cent not used for energy production is converted into these other materials. Petroleum is found in porous rock formations in the upper strata of some areas of the Earth's crust. There is also petroleum in oil sands (tar sands). Known oil reserves are typically estimated at around 190 km3 (1.2 trillion (short scale) barrels) without oil sands, or 595 km3 (3.74 trillion barrels) with oil sands.
