Are Glass Cups Safe

Toxicity: One of the key reasons we love glass is because it is so safe. It is generally completely inert (i.e., non-reactive and non-leaching) and is impermeable to liquids and gases. These inert and impermeable qualities of glass make it completely safe for food and drink usage.

Can glass be toxic?
