Labor bringing

Material Safety Data Sheets (OSHA Form 20, see Figure 1) are available from suppliers for every chemical sold. These give valuable information of a specific nature and should be kept on file. A phone call to the nearest office of the Occupational Safety and Health Administration (OSHA) of the U.S. Department of Labor will bring forth more information on safety, both oral and written. 

Despite their flaws, batch processes have stood the test of time for a number of reasons, the most important of which is the flexibihty it brings to the manufacturer in terms of the range of products that the plant can produce, the feedstocks used to produce them, and the speed at which they can be brought to market with very limited information on physical properties, reaction kinetics, and so on (very few, if any, Michelin-starred chefs have ever measured the rheology or kinetics of their latest culinary creation). This flexibility, however, has a price which comes in the form of lower efficiencies in terms of production, energy, labor, and so on, and ultimately efficiency equates to cost However, one should never underestimate the pull of flexibility particularly, as discussed earlier in the examples of fermentation, where control of important parameters is difficult to achieve. 

Man brings his labor power to the market, and he is alienated inasmuch as the factory owner extracts his surplus labor from him. This is what makes man a social being. And this is precisely what most scholarship on alchemy suppresses. Perhaps the dream of alchemy is not so much about infinite riches or spiritual renewal, but autonomy from the labor market. 

This volume is dedicated to all those whose names appear in Table X, in recognition of the labor that they have expended on assembling and bringing to its present state the enormous body of knowledge and understanding that is summarized here, and in the hope that it will both ease and help to guide their continued work In the future.
