important : Due to the good thermal conductivity of graphite, heat transfer is very fast and heat loss is small. Therefore, when you use it as a stir bar, you must use a thin wire to tie the graphite rod to the small iron bar or wooden chopsticks. On the one hand, increase the length, on the other hand, prevent burns. Remember!
