In materials science, “plastic” refers to the ability of a material to undergo permanent deformation under stress without breaking. Metals exhibit plasticity when they are subjected to stress beyond their elastic limit, allowing them to be shaped or formed. This property is distinct from the common use of the word “plastic” to describe synthetic polymers.
Geologically, ice is a mineral, aka a rock. If lava is just rock heated past its melting point, water is lava.
Henceforth, when walking on a frozen lake or river, one must declare that the floor is lava!
And thus when you sip on that ice tea in your hand, you are actually drinking liquid gold
If my grandmother had wheels, she’d be a bicycle
Metal is also elastic.
But that doesn’t mean metal is plastic or elastic in terms of material type, just the English sucks.
Ices are metals.
Perhaps you meant to say that ices are crystals?
No. In astronomy, everything heavier than hydrogen or helium is referred to as metals. So, a star’s metallicity would be including carbon, oxygen etc.
In my country we refer to gravel roads as metalled roads, for no reason I can explain.
