Crayon

A crayon (or wax pastel) is a stick of colored wax, charcoal, chalk or other material used for writing or drawing. A crayon made of pigment with a dry binder is a pastel; when made of oiled chalk it is called an oil pastel. A grease pencil or china marker (UK chinagraph pencil) is made of colored hardened grease. There are also watercolor crayons, sometimes called water-soluble crayons.

Crayons, which are available at a range of price points, are easy to work with, often less messy than paints and markers, blunt (removing the risk of sharp points present when using a pencil or pen), typically non-toxic, and are available in a wide variety of colors. These characteristics make them particularly good instruments for teaching small children to draw in addition to being used widely by student and professional artists.

Composition

In the modern English-speaking world, the term crayon is commonly associated with the standard wax crayon, such as those widely available for use by children. Such crayons are usually approximately 3.5 inches (89 mm) in length and made mostly of petroleum (paraffin wax). Paraffin wax is heated and cooled to achieve the correct temperature in which a usable wax substance can be dyed and then manufactured for use around the world. Paraffin waxes are used for cosmetics, candles, for the preparation of printing ink, fruit preserving, in the pharmaceutical industry, for lubricating purposes, and crayons.

Castle

A castle (from Latin: castellum) is a type of fortified structure built in Europe and the Middle East during the Middle Ages by nobility. Scholars debate the scope of the word castle, but usually consider it to be the private fortified residence of a lord or noble. This is distinct from a palace, which is not fortified; from a fortress, which was not always a residence for nobility; and from a fortified settlement, which was a public defence – though there are many similarities among these types of construction. Usage of the term has varied over time and has been applied to structures as diverse as hill forts and country houses. Over the approximately 900 years that castles were built, they took on a great many forms with many different features, although some, such as curtain walls and arrowslits, were commonplace.

A European innovation, castles originated in the 9th and 10th centuries, after the fall of the Carolingian Empire resulted in its territory being divided among individual lords and princes. These nobles built castles to control the area immediately surrounding them, and were both offensive and defensive structures; they provided a base from which raids could be launched as well as protection from enemies. Although their military origins are often emphasised in castle studies, the structures also served as centres of administration and symbols of power. Urban castles were used to control the local populace and important travel routes, and rural castles were often situated near features that were integral to life in the community, such as mills and fertile land.
