4. Saltwater Test A 30-day test was run on Hog Slat v.2, print 4 to test the durability of the fired clay in seawater (Fig. 23). It was submerged on 12/08/2021 and was taken out on 01/07/2022. We observed no signs of damage due to submersion in saltwater for 30 days. However, due to the glue, air bubbles started to form on the glue lines.
