Lewis, or Lewis Pins: A lifting device for blocks of masonry consisting of two cranked pins attached to a steel ring.

Lierne Rib: Ribs in a vault which run from rib to rib (roof boss to roof boss).

Lime: The bonding element in traditional mortars, plasters, renders and paints. Lime has been used in building work since Roman times, only displaced in the latter part of the 20th century by Portland Cement and gypsum based plasters. Made by burning limestone (calcium carbonate) in a kiln, which produces quicklime (calcium oxide) which is then slaked (calcium hydroxide) by adding water. Lime products set slowly by absorbing carbon dioxide and reverting back to calcium carbonate. Lime can be hydraulic or non hydraulic, hydraulic lime absorbs carbon dioxide and sets unassisted. Non hydraulic lime has to have the addition of potsolamic material (crushed fired clay or crushed Lias type limestone) to make it absorb carbon dioxide and set.

Lime Bloom: A whitish bloom that appears on the face of masonry if lime-rich water has been insufficiently washed from the stone’s surface during fixing or pointing.

Lime Pit: A pit where freshly slaked liquid lime is left to stand until it has matured and acquired the consistency of soft cheese.

Limewash: A traditional paint made using slaked lime and various colourings, such as ochre.
