Slaking
The shell powder from the kiln is heaped up into a pile and water is mixed with it. Smoke appears and the shell powder is converted to lime.
Sieving
A further day after the addition of water, the by now already slaked lime is sieved with a copper mesh sieve. The lumps of waste residue after sieving are thrown into the sea to reclaim it.
Bagging
The finished lime is bagged in hemp or grass-cloth sacks of about 100 cattys weight, and is then shipped on small boats to the buyers.
My family involvement in lime making
The San Shing Lei (新盛利) lime kiln factory operated by the Wong (黃) family has enjoyed a relatively lengthy history and occupied a distinguished place in the local lime kiln industry. Five generations of the family were involved in it, for more than one hundred years. The Wong family came originally from Chung Shan (中山) county, and our ancestor first came to Hong Kong shortly after Hong Kong was established, to operate a lime kiln in the Western part of the city (西區). Later, at various times, the kiln moved. This was because, as the area became prosperous and developed, so the kiln had to move away to quiet and undeveloped areas near the sea to carry on business. Lime burning is an offensive trade because of the large quantity of lime dust emitted, and also because of the heavy pall of smoke blown about in the first hour after the kiln is lit, while the dry grass is burning. In fact, during lime-burning, local residents and passers-by would all run away to try to avoid this smoke. However, the kiln is not dangerous to health — in fact, kiln workers all enjoy excellent health. The Wong family factory moved to several places: from Western District to Tsimshatsui (near the present railway station area), then to Tai Kok Tsui (near Fuk Wing Street), then to Shamshuipo.
