Engraving is a technique of incising a design onto a hard surface, such as metal, wood, or glass, using a sharp tool called a graver or burin. It is a form of decorative art that has been in practice for centuries.

There are several styles of engraving, including line engraving, stipple engraving, drypoint engraving, mezzotint engraving, and etching. Each style involves different techniques and produces distinct results.

Line engraving is a style of engraving that involves cutting lines into a metal plate with a graver to create a design. The lines can vary in width and depth to produce shading and texture. Line engraving is often used for detailed illustrations and maps.

Stipple engraving is a style of engraving that involves creating a design using small dots or stippling. The dots can vary in size and density to produce shading and texture. Stipple engraving is often used for portraits and landscapes.

Drypoint engraving is a style of engraving that involves scratching a design directly onto a metal plate using a sharp tool. The lines created by the tool are rough and irregular, producing a unique texture. Drypoint engraving is often used for expressive and dramatic prints.

Mezzotint engraving is a style of engraving that involves creating a tonal image using a metal plate that has been roughened with a special tool called a rocker. The roughened surface holds ink, producing a rich and velvety texture. Mezzotint engraving is often used for portraits and landscapes.

Etching is a style of engraving that involves creating a design on a metal plate by coating it with a wax or resin that resists acid. The plate is then bathed in acid, which bites into the exposed metal, creating the design. Etching is often used for fine art prints and illustrations.
