Mace
Botanical: Myristica fragrans
Family: N.O. Myristicaceae
Hindi Name: Mace - Javitri
General Description: Nutmeg, spice consisting of the seed of the Myristica fragrans, a tropical, dioecious evergreen tree native to the Moluccas or Spice Islands of Indonesia.
Geographical Sources
The nutmeg tree, Myristica fragrans, is indigenous to the Moluccas in Indonesia but has been successfully grown in other Asian countries and in the Caribbean, namely Grenada. Banda Islands, Malayan Archipelago, Molucca Islands, and cultivated in Sumatra, French Guiana
Composition -> Nutmeg and mace contain 7 to 14 percent essential oil, the principal components of which are pinene, camphene, and dipentene. Nutmeg on expression yields about 24 to 30 percent fixed oil called nutmeg butter, or oil of mace. Dried kernel of the seed.
Varieties -> Whole nutmegs are grouped under three broad quality classifications:
1. Sound: nutmegs which are mainly used for grinding and to a lesser extent for oleoresin extraction. High quality or sound whole nutmegs are traded in grades which refer to their size in numbers of nutmegs per pound: 80s, 110s and 130s (110 to 287 nuts per kg), or 'ABCD' which is an assortment of various sizes.
2. Substandard: nutmegs which are used for grinding, oleoresin extraction and essential oil distillation. Substandard nutmegs are traded as 'sound, shrivelled' which in general have a higher volatile oil content than mature sound nutmegs and are used for grinding, oleoresin extraction and oil distillation; and 'BWP' (broken, wormy and punky) which are mainly used for grinding as volatile oil content generally does not exceed 8%.
3. Distilling: poor quality nutmegs used for essential oil distillation.Distilling grades of nutmegs are of poorer quality: 'BIA' or 'ETEZ' with a volatile oil content of 8% to 10%; and 'BSL' or 'AZWI' which has less shell material and a volatile oil content of 12% to 13%.
Method of Processing -> When fully mature it splits in two, exposing a crimson-coloured aril, the mace, surrounding a single shiny, brown seed, the nutmeg. The pulp of the fruit may be eaten locally. After collection, the aril-enveloped nutmegs are conveyed to curing areas where the mace is removed, flattened out, and dried. The nutmegs are dried gradually in the sun and turned twice daily over a period of six to eight weeks. During this time the nutmeg shrinks away from its hard seed coat until the kernels rattle in their shells when shaken. The shell is then broken with a wooden truncheon and the nutmegs are picked out. Dried nutmegs are grayish-brown ovals with furrowed surfaces. Large ones may be about 1.2 inches long and 0.8 inch in diameter.
Taste and Aroma: Nutmeg has a characteristic, pleasant fragrance and slightly warm taste
Nutmeg
Myristica fragrans
Fam: Myristicaceae
The nutmeg tree is a large evergreen native to the Moluccas (the Spice Islands) and is now cultivated in the West Indies. It produces two spices — mace and nutmeg. Nutmeg is the seed kernel inside the fruit and mace is the lacy covering (aril) on the kernel.
The Arabs were the exclusive importers of the spice to Europe up until 1512, when Vasco de Gama reached the Moloccas and claimed the islands for Portugal. To preserve their new monopoly, the Portuguese (and from 1602, the Dutch) restricted the trees to the islands of Banda and Amboina. The Dutch were especially cautious, since the part of the fruit used as a spice is also the seed, so that anyone with the spice could propagate it. To protect against this, the Dutch bathed the seeds in lime, which would prevent them from growing. This plan was thwarted however, by fruit pigeons who carried the fruit to other islands, before it was harvested, scattering the seeds. The Dutch sent out search and destroy crews to control the spread and when there was an abundant harvest, they even burned nutmeg to keep its supply under control. Despite these precautions, the French, led by Pierre Poivre (Peter Piper) smuggled nutmeg seeds and clove seedlings to start a plantation on the island of Mauritius, off the east coast of Africa, near Madagascar. In 1796 the British took over the Moloccas and spread the cultivation to other East Indian islands and then to the Caribbean. Nutmeg was so successful in Grenada it now calls itself the Nutmeg Island, designing its flag in the green, yellow and red colours of nutmeg and including a graphic image of nutmeg in one corner.
Spice Description
The nutmeg seed is encased in a mottled yellow, edible fruit, the approximate size and shape of a small peach. The fruit splits in half to reveal a net-like, bright red covering over the seed. This is the aril which is collected, dried and sold as mace. Under the aril is a dark shiny nut-like pit, and inside that is the oval shaped seed which is the nutmeg. Nutmegs are usually sold without the mace or hard shell. They are oval, about 25 mm (1 in) in length, lightly wrinkled and dark brown on the outside, lighter brown on the inside. Nutmeg is sold whole or ground, and is labeled as ‘East Indian’ or ‘West Indian’ indicating its source. Whole nutmeg may be coated with lime to protect against insects and fungus, though this practice is giving way to other forms of fumigation.

Quartz is a hard, crystalline mineral composed of silica. The atoms are linked in a continuous framework of SiO4 silicon oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust.
It is hard, brittle, transparent material with a density of 2649 kg/m3 and a melting point of 1432°C. This naturally available quartz is mined by the company and processed for achieving the various size fractions as per customers requirements.
Once the high purity Quartz is procured from the mines, the material undergoes manual sorting, advanced colour sorting, state- of the- art magnet systems, proper sizing with high frequency vibrations to achieve the best material.

Ceramics
Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Usage and Dosage:
1. Industrially: ferrous sulphate heptahydrate is mainly used as a precursor to other iron compounds. It is a reducing agent, for the reduction of chromate in cement.
2. Nutritional Supplement: Together with other iron compounds, ferrous sulphate is used to fortify foods and treat iron-deficiency anemia. Constipation is a frequent and uncomfortable side effect associated with the administration of oral supplements. Stool softeners often are prescribed to prevent constipation.
3. Colorant: Ferrous sulphate can also be used to stain concete and some limestones and sandstones a yellowish rust color.
4. Water Treatment: Ferrous sulphate has been applied for the purification of water by flocculation and for phosphate removal in municipal and industrial sewage treatment plants to prevent eutrophication of surface water bodies.
