| Temper: The fire
hardening of a steel chisels cutting edge. The steel is heated until
cherry red, then dipped into water briefly at which point the temper colours
become visible, then when the desired colour reaches the cutting edge
(usually a blue or straw yellow) the tool is quenched and cooled. "If
its as blue as a ravens wing, its fit for anything".
Stonemasonry shops nearly always had a forge and basic blacksmithing tools
for the making and maintenance of fire hardened chisels. The coming of
tungsten tipped chisels has rendered this almost entirely obsolete.
Timber Hitch: A very simple knot used when raising boards (such as scaffold boards) using a gin wheel and rope.

Trimmer: A stooling left slightly proud of its final profile until the stone is fixed in the building in order to permit a certain amount of adjustment of its final position. The stooling is then trimmed to fit perfectly once its final position is fixed.
Tungsten: A very hard and hard-wearing metal, brazed into the shaft of modern chisels to provide durable cutting edges. Although highly resistant to abrasion, the tips are prone to fracture if the tool is mistreated.
