Talc is not a good choice when building a statue because Talc is one of the weakest minerals with a hardness of 1 on the Mohs Scale since it could be scratched by a fingernail, which means that when people build a statue with Talc, it could be easily broken down. There would be a better mineral to use, which could be marble because it could last longer than sandstone and is a lot more sturdier than Talc. Marble also could withstand the test of time better than some of the other minerals.
