An aerate/honeycombed soap product that is self-skinning and of a density less than that of water, is formed from the application of microwaves to a soap piece produced by a conventional soap-making process. The resultant product has increased in size by a factor of about 7, therefore making it a manageable size for both washing hand/face and body, yet dissolving into a high quality lathering froth after one use. The size can be further increased by the application of water spray and subsequent application of a further burst of microwaves. The manufacturing process can also be applied to soap pieces impregnated into a man-made sponge, with the result that the soap pieces increase in size and fill the porosity of the sponge, rendering it a semi-rigid bar. The process can be employed to form both moulded and free form tablets.
