Cork (material) in the context of "Bark (botany)"

A bandy ball is a rubber ball used for playing bandy and rink bandy. Bandy balls are manufactured by companies such as Jofa, Kosa, and Reebok.

The core of the ball is made of cork and is surrounded by rubber or rubber-like plastic. Balls should be manufactured in a diameter of 62.4 or 63.8 mm (2.46 or 2.51 in) (the latter is called a "Russian ball"). Originally, bandy balls were red, then later became orange or cerise. According to the Bandy Playing Rules set up by the Federation of International Bandy, any of these are allowed, but all balls used in one game must be of the same colour and type.

A cricket ball is a hard, solid ball used to play cricket. A cricket ball consists of a cork core wound with string then a leather cover stitched on, and manufacture is regulated by cricket law at first-class level. The trajectory of a cricket ball when bowled, through movement in the air, and off the ground, is influenced by the action of the bowler and the condition of the ball and the pitch, while working on the cricket ball to obtain optimal condition is a key role of the fielding side. The principal method through which the batter scores runs is by hitting the ball, with the bat, into a position where it would be safe to take a run, or by directing the ball through or over the boundary. Cricket balls are harder and heavier than baseballs.

In Test cricket, professional domestic games that spread over a multitude of days, and almost the entirety of amateur cricket, the traditional red cricket ball is normally used. In many one day cricket matches, a white ball is used instead in order to remain visible under floodlights, and since 2010, pink has been introduced to contrast with players' white clothing and for improved night visibility during day/night Test matches. Training balls of white, red and pink are also common, and tennis balls and other similar-sized balls can be used for training or informal cricket matches. During cricket matches, the quality of the ball changes to a point where it is no longer usable, and during this decline its properties alter and thus can influence the match. Altering the state of the cricket ball outside the permitted manners designated in the laws of cricket is prohibited during a match, and so-called "ball tampering" has resulted in numerous controversies.

A placemat or table mat is a covering or pad designating an individual place setting, unlike the larger tablecloth that covers the entire surface. Placemats are made from many different materials, depending on their purpose: to protect, decorate, entertain or advertise. Materials and production methods range from mass-produced and commercial, to local and traditional.

Linoleum is a floor covering made from materials such as solidified linseed oil (linoxyn), pine resin, ground cork dust, sawdust, and mineral fillers such as calcium carbonate, most commonly on a hessian or canvas backing. Pigments are often added to the materials to create the desired color finish. Due to the pigment being mixed directly into the linoleum cement, the finished color of the tile remains visible even after years of wear. In the past some of these pigments were iron oxide, red lead or lithopone.

It gained popularity as a beautiful and easy to clean flooring option in the late 19th century and is still used today. Commercially, the material has been largely replaced by sheet vinyl flooring, a plastic alternative made of polyvinyl-chloride, though many still call it linoleum. This is mainly due to the fact that its plastic counterpart is less costly and much faster to produce.

Suberin is a lipophilic, complex polyester biopolymer found in plants. It is composed of long-chain fatty acids (called suberin acids) and glycerol. Suberin is interconnected with cutin and lignin and forms a protective barrier in the epidermal and peridermal cell walls of higher plants. Suberin and lignin are considered covalently linked to lipids and carbohydrates respectively. Lignin is again covalently linked to suberin, and to a lesser extent to cutin, thus constructing a complex macromolecular matrix. Suberin is a major constituent of cork, and is named after the cork oak, Quercus suber. Its main function is as a barrier to movement of water and solutes.

Quercus suber, commonly called the cork oak, is a medium-sized, evergreen oak tree in the section Quercus sect. Cerris. It is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring and as the cores of cricket balls. It is native to southwest Europe and northwest Africa. In the Mediterranean basin the tree is an ancient species with fossil remnants dating back to the Tertiary period. It can survive for as long as two centuries. Typically, once it reaches 25 years old, its thick bark can be harvested for cork every 9 to 12 years without causing harm to the tree.

It endures drought and makes little demand on the soil quality and is regarded as a defence against desertification. Cork oak woodlands are home to a multitude of animal and plant species. Since cork for sealing bottles is increasingly being displaced by other materials, these forests are at risk as part of the cultural landscape and as a result animal species such as the Iberian lynx and imperial eagles are threatened with extinction.
