Abstract
Process and apparatus for the manufacture of synthetic precious stones, characterized in that the products to be melted can be considered as the raw material to be used for the synthesis of the stones to be obtained, as well as in essence will be aluminum sesquioxide or pure alumina with a variable proportion of metal oxides acting as dyes, according to the tone and color of the stone to be synthesized, being an indispensable condition that the mixture of the oxides be homogeneous, the impalpable powder to avoid clogging in the nozzle of the heat producing element to achieve a perfect integral fusion, as well as must be extremely dry to avoid the formation of gaseous bubbles in the melt.
