Hot mixed air lime mortars, with or without small volumes of pozzolanic addition, were the ubiquitous lime mortar of traditional construction around the world, only falling from general use as the 20thC wore on, when the use of Portland cement or hybrid Portland cement and industrially produced dry hydrated air lime mortars displaced them from most building sites. This shift coincided with the growing disempowerment of masons and other crafts in the industry. Previously, mortar design had been the domain of the craftsmen, and wherever they were in the world, they chose to use hot mixed air lime mortars.

These mortars were the most economically made; they were quickly and efficiently prepared (by a variety of simple methods) and delivered mortars of eminent workability and usefulness. They enjoyed unparalleled water retentivity and excellent bond, and displayed maximum cohesiveness and adhesiveness.

All of these properties were shared with traditional earth-lime mortars, a mortar of similar ubiquity, which had dominated masonry construction throughout Europe and the Middle East before the 18thC and which were still commonly used for bedding mortars and base-coat plasters across the Americas even into the 20thC. Hot mixed lime and traditionally slaked lime putties were always used in conjunction with these.

Hot mixed air lime mortars, with suitable pozzolanic addition according to purpose, are eminently breathable – they have a vapour permeability more than twice that of a typical NHL mortar; they are much more effectively porous than other mortars and keep building fabric dry. They are durable and frost resilient in a properly detailed traditional building and are easy to prepare and deploy.

Hot mixed lime mortars are truly like-for-like and are compatible with all traditional fabric in ways that modern Natural Hydraulic Lime simply is not. Natural Hydraulic Limes were not much used for building in the air before the later 19thC – they were used, if at all, for water and underground works and for concretes. They were not available in North America unless imported from Europe, although natural cement was produced and was used for similarly wet situations, or as a gauge to otherwise hot mixed mortars in thick-walled military construction during the 19thC.

The Worshipful Company of Masons is number 30 in the order of precedence of the Ancient Livery Companies of the City of London, as set by the Aldermen of the City in 1515. Today there are over 110 and the number continues to grow. The focus of our Livery Company is to preserve and encourage the use of natural stone in the built environment. This includes supporting the training of craftsmen as well as the preservation and appreciation of iconic historic stone buildings.

Happily stonemasonry is still practiced today and the Worshipful Company of Masons is at the forefront of supporting the craft in education and preservation. Our membership includes professionals from the construction and property, specialists in stonemasonry as well as those with connections to or interest in the City and its national and international importance. Membership is made up Liverymen, Freemen and Yeoman Masons.

Our history - Our Company was formed with the object of regulating the craft of stonemasonry so that standards could be properly maintained and rewarded. The earliest available records of regulation from the Court of Aldermen are dated 1356.

In 1472 a Grant of Arms was received under Letters Patent but it was not until 1677 that the Company was formally incorporated by Royal Charter under the seal of King Charles II which gave it authority to control the work of masons in the Cities of London and Westminster and seven miles around. This was a necessary power in order to control the influx of provincial stonemasons assisting in the rebuilding of the capital following the Great Fire in 1666 and to enable the maintenance of strict standards, although governance was never quite as tight again.

Since then members of the Company have been involved in the creation and preservation of the majority of iconic stone buildings and structures across these Cities and nationwide.

Joshua and Edward Marshall erected Temple Bar in 1673, the barrier from where trade was officially regulated into the City. Four years later Thomas Strong laid the foundation stone of the new St Paul’s Cathedral and his brother Edward laid the last stone of the building’s lantern in 1708. Both Marshalls and Strongs were Master Masons among a number of other prominent members of the Company who worked on the City’s most beautiful monuments under Sir Christopher Wren. Between 1670 and 1718 at least 8 individuals actively involved in the construction of St Paul’s became Masters of the Masons’ Company.
