Blue clay is particularly effective for mature or oily skin, and for dry or coloured hair. The benefits: Removes impurities, pollution and dead skin. Oxygenates the skin.

According to Inca mythology the creator god Viracocha formed humans from clay on his second attempt at creating living creatures. In Norse culture humans are made from sand in tree trunks. In the Korean Seng-gut narrative, humans are created from red clay.

Ball clay. The definition of clay is fine-grained soil or water-soaked earth. An example of clay is a soft blob of water-soaked earth or fine grain soil that you use when wet and pliable to sculpt a vase, which is then fired under high heat and becomes hard.

Clay minerals have a sheet-like structure and are composed of mainly tetrahedrally arranged silicate and octahedrally arranged aluminate groups. It is a 1:1 clay mineral – the basic unit is composed of a 2-dimensional (2D) layer of silicate groups tightly bonded to a 2D layer of aluminate groups.

Ceramics are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms. Once the ceramic has been shaped, it is fired in a high temperature oven known as a kiln. Often, ceramics are covered in decorative, waterproof, paint-like substances known as glazes.

Many metal fumes generated at high temperatures are highly toxic by inhalation. Since lead vaporizes at a relatively low temperature, it is especially hazardous. Carbon monoxide from fuel-fired kilns or the combustion of organic matter in clays is highly toxic by inhalation and can cause oxygen starvation.

Dust from ordinary clay and several other materials contains some free silica that is too fine and heavy to be expelled from the lungs. Over time this can cause fatal silicosis if breathed often enough. She said that the instructor had not cautioned them about the effects of clay dust.

Pottery and Ceramics – A Brief Explanation Pottery and ceramics are one and the same. The word ceramic derives from Greek which translates as “of pottery” or “for pottery”. Both pottery and ceramic are general terms that describe objects which have been formed with clay, hardened by firing and decorated or glazed.

CAUTION: A kitchen oven cannot be set hot enough to fire pots. Firing pots in any indoor stove is never recommend. It may cause a house fire. The temperatures needed to fire clay are too hot (1,000 F degrees and hotter).

Remnants of an Ancient Kitchen Are Found in China. Fragments of ancient pottery found in southern China turn out to date back 20,000 years, making them the world’s oldest known pottery — 2,000 to 3,000 years older than examples found in East Asia and elsewhere.

Porcelain, vitrified pottery with a white, fine-grained body that is usually translucent, as distinguished from earthenware, which is porous, opaque, and coarser. The distinction between porcelain and stoneware, the other class of vitrified pottery material, is less clear.

Stoneware: less porous than earthenware, stoneware is also more durable and has a lighter color (but is more opaque than porcelain). Porcelain: is the non porous option of ceramic. It has an incredible durability resulting from the high firing temperature. Porcelain is also resistant to microwave, oven and freezer.

The major difference between porcelain tile and ceramic tile is how it’s made. Both tiles are made from a clay mixture that’s fired in a kiln, but porcelain tile is made from more refined clay and it’s fired at higher temperatures. This makes it denser and more durable than ceramic tile.

Bone china is a type of porcelain that is composed of bone ash, feldspathic material, and kaolin. Bone china is the strongest of the porcelain or china ceramics, having very high mechanical and physical strength and chip resistance, and is known for its high levels of whiteness and translucency.

Bone china offers a slightly more elegant appeal due to the lighter weight and body composition. It’s typically a bit more expensive than porcelain due to its manufacturing process and overall elegant perception. Porcelain is generally thicker than bone china products.

High quality fine bone china contains at least 30% bone ash, enabling thin, walled pieces to be made with a more delicate appearance and translucency compared to porcelain, and allowing for greater chip resistance and durability. Fine bone china is thinner and lighter in weight than porcelain.

High Quality Materials for Durability, Made from extra strong toughened glass, the Larah by Borosil Mimosa Opalware glass dinner set is lightweight, highly durable and will last for a long time even with regular use. This dinner set is microwave-friendly and can be used to quickly heat your cold meals.

Considering this, is Opalware safe for health? Healthy dinnerware products are made out of opal glass and are non-porous in nature which means it does not absorb food particles curtailing bacteria formation, which makes your dinnerware 100% food safe & hygienic.

The dinner set features utensils made of melamine which is easy to maintain and durable, break-resistant, dishwasher safe, heat resistant. The 20 Pcs dinner set includes 6 full plates, 6 soup bowls, 6 quarter plates and 2 salt & pepper pots.

Break, chip and scratch resistant, made for everyday use. Dishwasher safe, micro wave safe and stackable. Fully tempered up to 3 times stronger, recyclable, easy to clean. Food grade, 100 percent hygienic.

Most melamine dinner ware is break-proof and shatter resistant, which is perfect for fast paced, high turnover environments. And whilst ceramic dinner ware does not hold the same reputation for durability, high quality ceramics with little to no lead content can prove just as hard wearing and chip resistant.

Melamine is a type of plastic found in many reusable plates, utensils, and cups. The FDA has ruled that melamine is safe to use, but that you shouldn’t use it in a microwave. However, if you’re concerned about melamine exposure from dishware, there are other options out there.

It has been found that melamine does not migrate from melamine-formaldehyde tableware into most foods. Foods and drinks should not be heated on melamine-based dinnerware in microwave ovens. Only ceramic or other cookware which specifies that the cookware is microwave-safe should be used.

Melamine is the base chemical which makes the robust melamine plastic tableware we so love because of its durability. Some research has found that placing very hot fluids (distilled water and acetic acid) in melamine plastic tableware for 30 minutes can cause melamine to leach into those fluids.

Are Corelle® products microwave safe? My plates and bowls become hot in the microwave. Yes, Corelle® dinnerware is oven safe up to 350° F (177° C) when used in accordance with the safety and usage Instructions that came with your product at the time of purchase.

Melamine-ware is safe for food use when used according to the manufacturer’s instructions. Melamine-ware should not be used for cooking or heating in microwave or conventional oven, holding hot oil, deep-fried foods, or storing highly acidic foods.
