Years ago I was being shown around an industrial parts supplier's warehouse. The guy who owned it was proudly telling me they sold all the parts used in the machines that make frozen pizzas because they had "food grade" parts. When I asked what made some of the tubes "food grade" he said "They're clear." I the made the mistake of asking, "How does that make them food grade?" and he explained that "All rubber hoses break down, and nobody likes to see black bits of rubber in their pizza sauce."
I think glass containers are a great, but until all of the harvesting, processing and packaging equipment is plastic free, I'd be shocked if the liquid inside didn't have microplastics in it, and hos much is probably more dependent on the factory than the container.
All I ask is a chance to prove that money can't make me happy.
