Recommendation There should be renewed support for advanced coal mining and processing research and development to optimize use of the nation’s coal resources by increasing the amount of coal that is economically minable through technological advances that penetrate the sand grains and cause a burn‐in defect • Therefore it is necessary to balance the base sand distribution and continue to screen the sand and use dust collectors during recycling to remove fines and to determine the proper bond addition • Most foundries in the United States use the
