Plastic vs other material V60's
I use a plastic V60 for pour-overs and find it quite good. I like the portability factor and that it's not so easy to break. However, I've read a couple of things suggesting that scalding water on plastics is not a good thing from a 'leeching chemicals' point of view.
I'm actually a scientist in my day job, so I'm very evidence-based and take these sorts of claims with a grain of salt. Having said that I can't even find what material the V60 is made of, to be able to do a literature search on whether any toxicity studies have been done. In the scheme of life, I'd be willing to bet it's no more detrimental to your health than stepping outside in the morning and breathing the air, but curiosity has gotten a hold of me.
Even though the ceramic/glass versions are probably a little nice aesthetically, the plastic version is completely functional and I'm having a hard time justifying the upgrade. Having said, are there any other better reasons to get one of the other models?
I guess those materials would have more thermal mass, so if preheated might keep the brew warmer - or suck out more heat otherwise. But I'd say it would be pretty marginal either way TBH.
I'm inclined to be sceptical of appeals to authority in general, but if it's approved food-grade material and intended to be in contact with hot water I wouldn't give it much thought. But if the ceramic/glass options appeal and health concerns help get you across the line, I say go for it
I'm no scientist, but how much scolding can really be done during a pour over?

Especially being plastic (quicker heat disbursement)
and the whole event shouldn't take you more than 3 minutes.
Is that enough heat and time for chemicals to start leeching out?
Thanks for that guys - I'll stick with the plastic then!
