I know that sometimes ceramics from other countries do not follow US FDA standards for lead content.I want to make tea in ceramic mugs but they are all made in china so I‘m afraid they‘ll leak lead.Also.is it safe to head substances in plastic cups or mugs? Like big ones that are meant to last.not the ones you can crush with you hand.Also is it safe to reuse plastic bottles?
The cup should be fine, it will be covered in a glaze with if there was lead in the ceramic then it wouldnt leak through, all my cups are made in china and im still here :D. And yes its perfectly safe to reuse plastic bottles, just make sure you wash them well or your next drink will taste a bit funny. and if you meant 'heat' in a plastic cup. them maybe, some melt when they have hot liquids in them. but you should be fine, like you said, they are the ones built to last, i heat liquids in those.
All kinds of phenols and ethyls leach out of plastics, the next generation will be as horrified as we are about lead now, these chemicals are the major suspect for mimicking female hormones and feminizing men, where dumped they change the sex of the fish and animals affected. The importers of the China will have made sure the goods are pucker, they don't want to have to take it all back and the Chinese invented the stuff!
