Openings left by the cores allow water, air and nutrients into the clay, so those essentials stay available and grass can grow healthy and strong. Gypsum enhances soil without affecting soil pH and provides calcium to prevent blossom end rot disease.
Improving soil structure and relieving compaction aren't the only ways that gypsum benefits your lawn and garden. Gypsum adds calcium and sulfur—essential plant nutrients—to your soil. While lime adds calcium and makes soil less acidic , gypsum adds calcium without affecting your soil pH. Adding gypsum to vegetable gardens helps prevent calcium deficiency, a primary cause of blossom end rot disease.
This common disease can undermine your harvest of garden favorites such as tomatoes, eggplants, peppers, and melons.
Adding gypsum at planting time keeps calcium plentiful, so fruit can ripen without end rot. The calcium in gypsum helps your strawberry patch reach its juicy potential, too.

The property of clay minerals that causes ions in solution to be fixed on clay surfaces or within internal sites applies to all types of ions, including organic molecules like pesticides. Clays can be an important vehicle for transporting and widely dispersing contaminants from one area to another.
Clays and clay minerals occur under a fairly limited range of geologic conditions. The environments of formation include soil horizons, continental and marine sediments, geothermal fields, volcanic deposits, and weathering rock formations.
Most clay minerals form where rocks are in contact with water, air, or steam. Examples of these situations include weathering boulders on a hillside, sediments on sea or lake bottoms, deeply buried sediments containing pore water, and rocks in contact with water heated by magma molten rock.
All of these environments may cause the formation of clay minerals from preexisting minerals. The transport and deposition of clays and clay minerals produced by eroding older continental and marine rocks and soils are important parts of the cycle that forms sedimentary rocks.
The ancient sedimentary rock record is composed of about 70 percent mudstones which contain about 50 percent clay-sized fragments and shales which are coarser than mudstones but which may contain clay-sized particles Blatt and others, Today, sedimentary environments that contain muds cover about 60 percent of marine continental shelves and 40 percent of deep ocean basins; continental aquatic environments such as lakes, rivers, estuaries, and deltas also contain high proportions of fine-grained sediments Hillier, , p.
Clearly, clays and clay minerals are critical components of both ancient and modern sedimentary environments. Diagenesis is the in-place alteration of a mineral to more stable forms, excluding surficial alteration which is weathering ; diagenesis occurs, for example, when minerals stable in one depositional environment are exposed to another by burial and compaction.
Common silicate materials such as quartz, feldspars, and volcanic glasses, as well as carbonates, noncrystalline iron oxides, and primary clay minerals, are transformed during diagenesis into more stable clay minerals mainly by dissolution and recrystallization. The formation of bentonite beds containing smectite-group clay minerals including montmorillonite and fuller's earth a type of clay mineral deposit that has high capacity to absorb water may occur primarily by diagenesis, although some deposits may also form by hydrothermal processes.
Bentonite beds usually form from altered volcanic ash, but other types of rock may also serve as sources. The absorptive properties of bentonites and fuller's earth make them ideal for such diverse uses as drilling mud; foundry-sand bond; binder for pelletizing iron ore and bleaching liquids; absorbents for oil, grease, and animal waste; and carriers for pesticides and fertilizers. Bentonite is also used as a soil liner for environmental containment applications and with polyacrylamide for making paper.
Weathering of rocks and soil is the primary way that clays and clay minerals form at the Earth's surface today. The weathering process involves physical disaggregation and chemical decomposition that change original minerals to clay minerals; weathering is uneven, and many stages of breakdown may be found in the same clay sample.
Factors governing rock weathering and soil formation include the initial type of rock, the ratio of water to rock, the temperature, the presence of organisms and organic material, and the amount of time. The types of clay minerals found in weathering rocks strongly control how the weathered rock behaves under various climatic conditions such as humid-tropical, dry-tropical, and temperate conditions.
Kaolinite is found in most weathering zones and soil profiles. Use a needle to recreate a vent hole if your model has an air pocket. For models that have a closed-off pocket of air, include a vent hole to prevent cracking due to temperature changes in the oven. Pierce the clay with a needle all the way through until you reach the inner air pocket.
Be sure to pierce at least 1 hole for each air pocket to ensure proper venting. For example, many clay models of animals have an air pocket inside to make them lighter. Read the directions on the package to locate the baking temperature. Most brands have the amount of temperature labeled on the package, which can range from Check the packaging to see if the baking temperature changes based on the thickness of the clay, and set the temperature on the oven.
Place the clay on a ceramic baking dish. While the oven heats up, transfer your clay model onto a piece of oven-safe ceramic. You can use a baking dish, like a ceramic pie dish, or even a ceramic tile. Avoid using metal or glass, which tend to fluctuate in temperature. Bake the clay immediately after painting or glazing. Adding a glaze or paint might add to the baking time of your model.
In general, for each coat or paint or glaze, add minutes onto the baking time. Bake the clay for the amount of time specified on the package. Most brands of clay have a bake time somewhere between minutes, depending on the thickness and color of the clay. Fill a large bowl with ice and water while the clay is baking. Get a large cooking pot or bucket that will fit your clay model. Then, fill it with ice water, with about 2 inches 5. You want the clay to be completely submerged in the water, so try to use as large of a pot as possible.
Remove the clay from the oven and dunk it into the water immediately. Once the clay has reached its baking time, use a spatula to separate it from the ceramic. Carefully transfer the model to the pot, and submerge it in the ice bath for at least 30 seconds to prevent the clay from over-baking.
Then, carefully remove the model with your hands or a pair of tongs. When you remove the clay from the oven, it might be somewhat soft on the outside, and some tools, like tongs, can leave marks and indentations on the hot clay.
Only use the tongs to remove the clay from the ice bath, not put it in. Method 2. Let the clay sit for hours to dry. Keep the clay in a dry, well-ventilated area, and leave it undisturbed. Every hours, check on the clay to look for cracks or chips, and make sure the clay is hardening.
The drying time will vary based on the thickness of the clay and the moisture in the air, but most types of air dry clays will be completely dry within 72 hours. Check on the clay often. Repair any cracks that appear during the drying process. To smooth them over, dip your fingers into a glass of clean water, and rub the water over the imperfection a few times to smooth it out.
This involves adding a small amount of water to the clay, and placing it in a plastic bag to sit for about 10 minutes. Then, knead the clay and continue adding small amounts of water until it is usable. Turn the clay after hours have passed. If your clay model is multidimensional, like a pot or a piece of jewelry, flip the piece over to let the bottom dry.
Try to avoid touching it for longer than you absolutely need to. Wait to paint the clay until after it has dried. Adding color or a design to your clay is easy. Simply wait until the clay has dried, and use a paintbrush to apply acrylic or tempera paint. Then, let the paint dry for 24 hours, and protect the paint by using a spray-on or brush-on paint sealant all over the clay.
Because modeling clay is oil-based. If you put the clay in the oven it will melt and could start a fire. Not Helpful 54 Helpful
