Tin,
Element with atomic number 50, symbol Sn, atomic weight 118.71, mp 231.8ºC, specific gravity (grey) 5.75, (white) 7.31. A soft white lustrous metal obtained mainly from the mineral cassiterite, SnO2, but stannite (Cu2SnFeS4) occasionally occurs in ore grade concentrations. Tin is not affected on exposure to air at ordinary temperatures. At temperatures above 13.2ºC the white tetragonal allotropic form is stable and below this the grey cubic form may exist. Above 170ºC, tin is rhombic in crystal structure. The metal has low tensile strength and hardness but good ductility. Mechanical deformation of white tin makes a distinct sound - tin cry - due to the formation of deformation twins.

Tjanting,
A tool used exclusively in Java for drawing with wax. It consists of a copper or brass receptacle having one or more spouts, which is mounted on a bamboo or reed handle.

Tjap (block),
A wax printing block made entirely of metal strips and open at the back. It was introduced in the latter half of the nineteenth century to facilitate speedier production in Java.

Toby printing,
A method used in block printing when the different colour areas of a design were clearly separated from each other; the colours were applied by means of a divided sieve and were thus printed at the same time from one block.

Tradition-Based Creations and Innovations,
Traditions are a set of cultural practices and ideas, which are considered to belong to the past and which are designated a certain status. Tradition-based creations or innovations refer to innovations and creations based on traditional knowledge as such, developed and innovated beyond a traditional context. Traditional knowledge as such refers to “knowledge systems, creations, innovations and cultural expressions that: have generally been transmitted from generation to generation; are generally regarded as pertaining to a particular people or its territory; have generally been developed in a non-systematic way; and, are constantly evolving in response to a changing environment.” Tradition-based innovation refers the case where tradition is a source of innovation by members of the relevant cultural community or outsiders, and can also identify others uses of tradition relevant to an intellectual property analysis. The “List and Brief Technical Explanation of Various Forms in which Traditional Knowledge may be Found” discusses traditional knowledge “as such” and traditional knowledge-based creation and innovation further.
