A method of making a composite product, such as a basin or a tile, includes the steps of impregnating particles of an exfoliated vermiculite or a lignocellulosic material with an impregnating composition comprising a first thermosetting resin, an extending liquid for the thermosetting resin, if necessary a catalyst for the thermosetting resin and a colouring agent for the particles; removing the extending liquid; subjecting the impregnated particles to suitable conditions, generally of temperature and for pressure, to polymerise or cross-link the first thermosetting resin; coating the particles so produced with a binder composition comprising a second thermosetting resin and if necessary a catalyst for the second thermosetting resin; forming the particles into a desired shape, either in a mould or on a plate of a press; and subjecting the particles to suitable conditions to polymerise, condense or cross-link the second thermosetting resin to bind the particles together to form the composite product.
