I am curious what material the Halo Triton tanks are made of. I have heard that some juices might crack or deteriorate some tanks, and want to be sure that the tanks I have will be okay with high acid, cinnamon or other flavors that might be detrimental to the integrity of Triton tanks. Glass or Pyrex tanks, from what i've studied, should be ok with most juices, whereas plastic will be less durable. Health is my main concern, and I do not think that vaping dissolved tank residue will be good for my lungs.
