1. A method for manufacturing artificial stone slabs with variegated veins, comprising the steps of:
a first step of depositing a first mixture containing resin and aggregate minerals into a first mold;
wherein the first mold is a supporting structure;
a second step of preparing two or more intermediate mixtures containing resin, and at least one of colorant and aggregate minerals;
combining the two or more intermediate mixtures using at least one blending technique in order to obtain a variegated second mixture; and
wherein the variegated second mixture contains two or more colors or gradients; and
further comprising an additional step of depositing the variegated second mixture into a predefined position in the first mold;
wherein all or part of the second step and the additional step are computer controlled;
wherein the first step further comprises forming grooves in the first mixture in the first mold;
wherein the additional step further comprises depositing the second mixture into the groove;
wherein the step of combining two or more of the intermediate mixtures using at least one blending technique includes:
layering two or more intermediate mixtures on top of each other;
compressing the layered two or more intermediate mixtures;
disrupting the layered and compressed two or more intermediate mixtures to form a fragmented layered compressed two or more intermediate mixtures, and
compressing the fragmented layered compressed two or more intermediate mixtures to obtain the variegated second mixture, and

wherein the additional step includes cutting the variegated second mixture into a plurality of strips with each of the plurality of strips having approximately the same width as a corresponding portion of the grooves, depositing the plurality of strips, piecing together each of the plurality of strips into a corresponding position of the grooves.
