The difference one can identify between the both is that the solitary flowers are the female flowers and flowers in clusters are male flowers. The pale yellow and spherical shape fruit has a longitudinal groove in the centre. When this fruit matures, it bursts open. It contains the bright attractive mace which covers the nutmeg which is a hard black, shiny shell of the seed. USES Both the spices are used as condiment especially in sweet eatable items. Food processing industry make use of this spice in ground form. It uses this powder as a standard seasoning in Dutch dishes. Nutmeg oleoresin finds usage in preparing confectioneries, baked foods, soups, meat products, sauces, meat & vegetable seasoning. The fruit's outer cover with adequate amount of flesh can be pickled or crystallized, or can be made into jellies. Mace is generally used in savory dishes. Eastern countries use it as a drug, attributable to its astringent, aphrodisiac, carminative and stimulant properties. If taken in excessive amount, it can have a narcotic effect. Nutmeg oil is used for making cosmetics and toiletries.

Kaolin application 1, kaolin industrial use Kaolin has become a paper, ceramics, rubber, chemicals, coatings, medicine and national defense, and dozens of other industries essential mineral raw materials. Ceramic industry is the first application of kaolin, a large amount of industry. The general dosage is 30% ~ 20% of the formula. Kaolin in ceramic effect is the introduction of Al2O3, is conducive to the formation of mullite, to improve its chemical stability and strength of sinter, in firing kaolin soil derived from the decomposition of mullite, forming the main frame of the strength of the green compacts, can prevent the products from deformation, firing in a wider temperature range, also can make the green body with certain whiteness. At the same time, kaolin has certain plasticity, adhesive, suspension and ability to bind endowed with porcelain clay, glaze good formability, make ceramic mud blank to billet car and grouting, easy to shape. If used in the wire, can increase the insulation, reduce the dielectric loss. Ceramic not only on kaolin clay plasticity, binding, drying shrinkage, dry strength, sintering shrinkage, sintering properties, refractoriness and burn whiteness have strict requirements, but also relates to the chemical properties, especially the presence of color elements caused by iron, titanium, copper, chromium, manganese and other, to burn after the brightness decreases, produce spots. Of kaolin particle size is smaller, the better, the porcelain clay has good plasticity and dry strength, but the rapid casting, accelerate the grouting speed and the dehydration rate of the casting process, the need to improve the batching particle size. In addition, kaolinite crystallization degree of difference, will also significantly affect the process performance of the porcelain, crystallization degree, plasticity, binding capacity is low, drying shrinkage of small, high sintering temperature, the impurity content also reduced; on the contrary, the plasticity is high, dry shrinkage of large, low sintering temperature, corresponding impurity content is also high. 2, kaolin in the field of cosmetics applications Kaolin is also known as the white porcelain, is a kind of clay mineral, usually white. In beauty, kaolin is usually used on the mask, it can absorb the oil and waste of the skin, clean the skin to remove dirt, and the town of Jingan to ask the fragile skin. The loss of water and nutrients from the mineral supplement in natural mud, balance oil secretion, make the skin more smooth, more flexible.

Sulfur or sulphur (British English; see spelling below) is a chemical element with symbol S and atomic number 16. It is an abundant, multivalentnon-metal. Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S8. Elemental sulfur is a bright yellowcrystalline solid when at room temperature. Chemically, sulfur can react as either an oxidant or reducing agent. It oxidizes most metals and severalnonmetals, including carbon, which leads to its negative charge in most organosulfur compounds, but it reduces several strong oxidants, such asoxygen and fluorine. Sulfur occurs naturally as the pure element (native sulfur) and as sulfide and sulfate minerals. Elemental sulfur crystals are commonly sought after by mineral collectors for their distinct, brightly colored polyhedron shapes. Being abundant in native form, sulfur was known in ancient times, mentioned for its uses in ancient India, ancient Greece, China and Egypt. Fumes from burning sulfur were used as fumigants, and sulfur-containing medicinal mixtures were used as balms and antiparasitics. Sulfur is referred to in the Bible as brimstone (burn stone) in English, with this name still used in several nonscientific tomes.[3] It was needed to make the best quality of black powder. In 1777, Antoine Lavoisier helped convince the scientific community that sulfur was a basic element, rather than a compound. Elemental sulfur was once extracted from salt domes where it sometimes occurs in nearly pure form, but this method has been obsolete since the late 20th century. Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas andpetroleum. The element's commercial uses are primarily in fertilizers, because of the relatively high requirement of plants for it, and in the manufacture of sulfuric acid, a primary industrial chemical. Other well-known uses for the element are in matches, insecticides and fungicides. Many sulfur compounds are odoriferous, and the smell of odorized natural gas, skunk scent, grapefruit, and garlic is due to sulfur compounds.Hydrogen sulfide produced by living organisms imparts the characteristic odor to rotting eggs and other biological processes.
