dc.description.abstract Laboratory tests show that five underclays from western and southwestern Indiana are potential sources of bonding clay for foundries. Green and dry strength tests were dteremined for each sample, obtained from a commercially used bonding clay. The particle-size distribution and the mineral composition of the underclays are most important in interpreting the results of physical tests. The samples which had a high clay content and a rather high percentage of montmorillonite produced the best green and dry strength test results. Five areas in Indiana are most favorable for commercial production of bonding clays. en
