During evaporation, the nickel/iron will melt and adhere to the crucible liner walls. Upon cooling and reheating (if it makes it that far), the difference in thermal contraction and expansion of the nickel/iron and the FABMATE® liner will cause immense stress on the liner and it will crack. Therefore, the crucible is limited to only one run.
