An unstitched waist-cloth, passed between the legs and tucked; a common male dress in northern India.

Dhoti,
A rectangular length of unstitched cotton cloth (usually approximately four yards long and made of thin muslin) which is tied to form a loose pair of trousers. Worn by Hindu men.

Dhoti,
A man’s lower unsewn garment of two and half yards draped between the legs and folded in at the waist. Hindu widows saris are also referred to as dhoti, as they are of similar white cloth with a very narrow border.

Dhuna,
Black tar-like substance that becomes pliant and elastic upon the application of heat. It is extracted from the secretion of a particularly tree.

Die,
A small cylinder of steel which is hand-engraved with one or more repeats of a small-scale pattern, then hardened and used to produce the mill.

Diffusion,
The movement of one type of element through another without reaction. Many of the important processes in metallurgy are controlled by diffusion. During solidification, the rate of diffusion of the elements in liquid ahead of a freezing front control whether the solid grows in planar, cellular or dendritic manner. In the solid state, many phase formation, and growth processes are controlled by diffusion. These diffusion controlled processes can be suppressed by rapid-cooling (quenching).

Diffusion bonding,
A method of joining to pieces of metal without melting. When two chemically clean metal surfaces, are placed together and heated under pressure but to temperatures under that of the melting point of either of the alloys involved, the atoms in the surface diffuse so that the bond and voids are eliminated.

Dimension,
Measure of length, width, or depth. Two-dimensional art, such as a painting, has length and width. Three-dimensional art, such as sculpture, has length, width, and depth.

Direct dyes,
A class of dyeing which can be applied to cotton and other vegetable fibres without the use of a mordant. They are easy to apply but on cellulose fibres are only of moderate wash fastness.

Direct Process (iron smelting),
Another name for the bloomery process, so named as malleable iron (bloomery iron) is produced directly from the ore. Unlike the indirect, or blast furnace process in which cast iron has to be refined to a malleable form (wrought iron, puddled iron, mild steel). Direct Process (brass making)

Direct style,
The type of textile printing in which the mordant and the colouring matter are applied simultaneously. It was very rare until the development of artificial dyestuffs.
