True, and if you want to go deeper into this rabbit hole

Woods: choose wisely because some types of wood + moist may be an environment for aspergilus flavus (alfatoxin producer), I’m not much knowledgeable for these thing but stick to traditionally used ones probably better


Glass: I work in analytical laboratory and I prefer borosilicate over sodalime for their chemical inertness (I don’t want glasses chemical to interfere my results)
And for crystals ? I don’t have experience with them, it is rare to me.

Metal: least preferred choice to me, but risk of heavy metal probably lower than risk of plastic additives
