  1. Chih Yuen refers to the Chinese cruiser Chih Yuen shipwreck; Nanhai No.1 refers to the Nanhai No.1 shipwreck. *These samples (samples Nos. 1 to 9) were also included in the Chen et al. study, and their MWC and BD have been tested [32]. Samples Nos. 10 to 30 are new samples of unknown state of preservation and independent of the Chen et al. study, and their MWC and will be tested in this study
  2. MWC stands for maximum water content; BD represents basic density
