Abstract

The invention relates to a manufacturing process of clay ornaments, clay with plasticity index of 5-9 is taken as raw material, and the following steps are adopted: the first step: pretreatment and drying; the second step: crushing or tabletting and aging; the third step: mould pressing; and the fourth step: air-drying and post-treatment. The clay with the better plasticity index is utilized, or thermal refining is performed on the ordinary clay so as to enable the clay to achieve the better plasticity range, and the clay ornaments with low cost, attractive appearance and no cracks can be simply and quickly manufactured through the processes of drying, crushing, aging and mould pressing; and various waterproof and weathering-proof fine ornaments with high degree of imitation of antique imitation, copper imitation and the like can be manufactured by coating waterproof coatings on the surfaces and coloring with paints.
