Hi, I fail to see how sand sintering could be a good material for use in the walls in a watertank. I think there is better materials by now that are not so brittle. Like plastic lining for example that would save time, money and work better for this purpose i think.
Stintering look more suited for smaller object maybe to melt some and pour it in a form to make dinner plates or glasses. Or make some small stationary pots or small barrels
