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!
can provide customization graphite product, mold, crucible, bar, ball, plate, scraper ect...
