Procedure: Add A to the main vessel and start prop mixing. Disperse B into A. Add C into A and continue mixing until completely clear and homogenous. In a separate vessel, combine D and start heating with mixing to 50°C. Add E to D. When DE is at 50°C, add F and stop heating. When fully dissolved, add G to DEF. When fully dispersed, with mixing but without aeration, add DEFG to ABC. When the batch is fully-formed, switch to sweep mixing. Premix H. Add H to batch. When batch is homogenous, add J and replace any water lost during processing.
