Undaunted by the flood of adverse criticism which they provoked, the inventors requested the industries to which soap is essential, and which were being harassed by the lime-soap bugbear, to subject the discovery to a commercial test. They did so, and were so surprised at the results obtained as to ask promptly for further supplies! It not only offered them the means to reduce their consumption of soap, but it performed the desired functions more efficaciously, and proved to be a complete panacea for the many ills which had heretofore afflicted the trade. So impressed were they by what the new detergent accomplished that they established its use in their works there and then, and to this day have never reverted to the article formerly used. In the powder form the application of the cereal soap was somewhat restricted. Accordingly the inventors decided to produce it in the familiar tablet and bar form, to enable a wider appeal to be made, even to the home. As events proved it was far easier to attain the meal stage than to pass therefrom to the solid cake. In fact, at one time it seemed as if this desired end would never be consummated. It was only by dint of unflagging effort that success was ultimately secured, and the soap in tablet and bar form introduced to the market. As the manufacture of soap from waste vegetable bases represents something entirely new, so do the actual methods of production. The revolution is complete. In preparing the conventional soap from 10 to 16 days are necessary. By the new process the cereal soap can be made in sixty minutes! Furthermore, the operation is clean, absolutely free from odour, and cold, no heat whatever being required, except to warm the factory during the winter for the comfort of the employees. The machinery necessary is also of the simplest and most inexpensive character. Under these conditions there is not only a very marked saving in time, but of fuel and labour. In these high-pressure days wastage of time is as criminal as the wastage of material, and one logically asks why spend ten days in consummating a specific end when one hour will suffice for the purpose? The saving in capital expenditure is very impressive, being at least 75 per cent. below that demanded for equipping the conventional factory. In other words, £10,000--$50,000--will provide an installation capable of turning out as much cereal soap as could be recorded with a plant costing £40,000--$200,000--devoted to the orthodox system.
