.I^SODUCTIQi,:
This report covers the batches of GB-443-D made between December 194*? and March 1946. A plant standard had already been set up on a new formula of increased batch size, K-2250, and the batches here reported were all made on that formula. Earlier develop ment study has been reported in KN-45-101.
SUMMARY AKD CONCLUSIONS:
Eight plant batches were made, three of which were OS Straight, the remainder were readily consumed in mixes*
Development Section supervision was quite cursory, being limited to checking batch cards and prescribing small changes in acid weight for control of pH.
Performance was deemed satisfactory, and the plant assumed supervision in March, 1946.
EXPERIMENTAL DETAILSi
Details of the batches and mixes are contained in DSN-46-43*
