A ceramic is a non-metallic solid material comprising an inorganic compound of metal, non-metal or metalloid atoms primarily held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, vitrified, and often completely amorphous (e.g., glasses). Most often, fired ceramics are either vitrified or semi-vitrified as is the case with earthenware, stoneware, and porcelain. This makes them breathable, washable and resistant to the warmth and humidity of the incubator environment.
Varying crystallinity and electron consumption in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators (extensively researched in ceramic engineering). With such a large range of possible options for the composition/structure of a ceramic (e.g. nearly all of the elements, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is vast, and identifiable attributes (e.g. hardness, toughness, electrical conductivity, etc.) are hard to specify for the group as a whole. General properties such as high melting temperature, high hardness, poor conductivity, high moduli of elasticity, chemical resistance and low ductility are the norm, with known exceptions to each of these rules (e.g. piezoelectric ceramics, glass transition temperature, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fiber, while containing ceramic materials, are not considered to be part of the ceramic family. It may be tremendously hard for one to grasp every aspect.
CUTTER KOREA has created something that can be life-changing. All across the globe, spanning 7 continents, there’s one thing that unites men – shaving problems. Although, it is one of those things that men are expected to know in life, like tying your shoelace, it’s apparently not! Every other day, depending on your routine, you drag a sharp blade across your face, dipping into small crevices, cuts or burns. It’s no wonder that shaving comes with a lot of potential problems. However, Cutter Korea comes to your rescue with a list of everyday shaving goof-ups, and more importantly, how to address them. There is nothing quite as frustrating as cleaning up with a close shave, only to suffer from a razor burn. These are the patches of red, irritated skin that appear within minutes of shaving. Mostly caused by using a blunt blade, dry shaving, or shaving too fast, it can be treated easily. You just need to soften your skin before taking a razor to your face. Prep up by applying shaving oil, using a gel-based cream for actual shaving and finishing up with a soothing moisturizer. It is also important to use a new razor with sharp blades.
