hey man,

just keep diggin around mate, we have 3 different clay pits at ours – all about 2ft below the surface but so worth it once you find it. dig dig dig dig diggin…!! that’s the secret. even if you only find a little bit, mix it around with other soil and sweet lips will be all yours.

Clay minerals are typically formed over long periods of time by the gradual chemical weathering of rocks, usually silicate-bearing, by low concentrations of carbonic acid and other diluted 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 residual deposits in soil, but thick deposits usually are formed as the result of a secondary sedimentary deposition process after they have been eroded and transported from their original location of formation. Clay deposits are typically associated with very low energy depositional environments such as large lakes and marine deposits.

Primary clays, also known as kaolins, are located at the site of formation. Secondary clay deposits have been moved by erosion and water from their primary location.

Clays are distinguished from other fine-grained soils by differences in size and/or mineralogy. Silts, which are fine-grained soils which do not include clay minerals, tend to have larger particle sizes than clays, but there is some overlap in both particle size and other physical properties, and there are many naturally occurring deposits which include both silts and clays. The distinction between silt and clay varies by discipline. Geologists and soil scientists usually consider the separation to occur at a particle size of 2 µm (clays being finer than silts), sedimentologists often use 4-5 μm, and colloid chemists use 1 μm.[1] Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils’ Atterberg Limits. ISO 14688 grades clay particles as being smaller than 2 μm and silts larger.

Depending on the academic source, there are three or four main groups of clays: kaolinite, montmorillonite-smectite, illite and chlorite. Chlorites are not always considered a clay, sometimes being classified as a separate group within the phyllosilicates. There are approximately 30 different types of “pure” clays in these categories, but most “natural” clays are mixtures of these different types, along with other weathered minerals.

Varve (or varved clay) is clay with visible annual layers, formed by seasonal differences in erosion and organic content. This type of deposit is common in former glacial lakes. When glacial lakes are formed there is very little movement of the water that makes the lake, and these eroded soils settle on the lake bed. This allows such an even distribution on the different layers of clay.[3].

Quick clay is a unique type of marine clay indigenous to the glaciated terrains of Norway, Canada, Northern Ireland and Sweden. It is a highly sensitive clay, prone to liquefaction, which has been involved in several deadly landslides.

Peace out…

i totally agree with the scinetific explination mainly because its scinentific but also cos its the same as us we have a couple of pits at my woods all spread out and fairly deep just to find clay

I found my clay on craig’s list.

will if you wrote that you deserve a medal. (blatant wiki-rape)

yeah,our soil is bunday, everywhere at the top of the woods, you cant get a spade down without hitting rock, but further down the hill and to the far side, 2 spades in and you have magic pink clay, (similar to digmore, i will have to consult with william and do some samples) whatever you build this tuff should go on the top, a good amount of it oo, otherwise it will dry/flake off, go spongy… then beat the hell out of it like chuck norris beats women, then water that shit, sweep it, let it dry and you will have pritiiiine lip time baby.

holla x

Forgot also clays are more likely to be on the shores of creekbeds where the force of the water has compacted the land.

clay is god for shaping because you can get it seriously hard but it cracks like a bitch, our trails you dig half a spade and your at clay, you dig 2 ft and you get to blue clay and another 2ft you get to rock, just dig around but i think its mainly to do with the soil type in your area, you could always ship it in?

if you really can’t find any in the end, this stuff might help if you can get your hands on some, we got luck and were given a few jugs ’cause it’s hard to find at our trails too..
