Whether for religious, cultural, economic or environmental reasons, horn has been considerably exploited and processed through the centuries by various civilisations.
Today, horn processing is still a widespread traditional activity in many countries, although on a very small scale. Paradoxically, there is no simple method of assessing the socio-economic impact of this craft partly because horn processing is usually a marginal activity and thus hardly perceptible in terms of revenue or job creation. An assessment still remains to be made.
The main purpose of this handbook is to introduce the technological aspects of horn processing in an easily understandable form, so as to facilitate the development of this activity. It has not been possible, owing to a lack of reliable data, to indicate the cost, price and sales price of the articles produced or the employment generated.
We believed it would be useful, however, to provide readers with a few basic data that would enable them to estimate the production cost of the articles described in this handbook. Machine time and labour requirements are given for small-scale manufacture of horn products (maximum 10 articles). For a non-mechanised workshop where all operations are manual, the times indicated in the table are to be multiplied by five to obtain the equivalent machine time.
To determine the cost price of electrical appliances (lamps, wall lights), the cost of electrical inputs (contact sockets, wires, plugs and switches) must be added to the production cost.
