Hot Water Bottle
A hot-water bottle is a bottle filled with hot water and sealed with a stopper, used to provide warmth, typically while in bed, but also for the application of heat to a specific part of the body. Early history Containers for warmth in bed were in use as early as the 16th century. The earliest versions contained hot coals from the dying embers of the fire, and these bed warmers were used to warm the bed before getting into it. Containers using hot water were soon also used, with the advantages that they could remain in the bed with the sleeper and were not so hot as to be a fire risk. Prior to the invention of rubber that could withstand sufficient heat, these early hot-water bottles were made of a variety of materials, such as zinc, copper, brass, glass, earthenware or wood. To prevent burning, the metal hot water flasks were wrapped in a soft cloth bag. Rubber bottles "India rubber" hot-water bottles were in use in Britain at least by 1875. Modern conventional hot-water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

Bolata ( bg, Болата) is a small cove and Nature reserve located in the Northern Bulgarian Black Sea Coast. Bolata is a locality located in the bay of the same name and is part of the Kaliakra Reserve. It is located in the northern part of the Bulgarian Black Sea coast near the village of Bulgarevo and near a former military station. The area is a wetland of great importance for few rare plant and animal species. The sandy beach is of natural origin and is unique for scandalous shores in the Kaliakra area. A small river has created a narrow gorge and flows into the swamp "Bolata" (Lake Bolata) with an area of 23 ha, covered with a vast mass of reeds. The limestone rocks in the area should be red in color, creating iron oxides in the clay that fill their cracks. The bay is part of the Natura 2000 Kaliakra Complex protected area.
