You can get seed from a head of cabbage if you grow it yourself. It is a biennial vegetable so it will grow the head the first year and if you leave it in the ground over the winter it will sprout seed heads the next year. You can buy seeds to plant or you can also find seedlings to transplant at garden centers.
Copper and bronze do not contain any iron, and only iron can rust (because rust is defined as iron oxide, a compound of iron and oxygen); so the answer is that steel will rust the fastest and copper and bronze will never 'rust'. But, yes, copper and bronze do tarnish, they do corrode.
Take off the rust with a rust remover product or scrub the rust away with steel wool. Apply primer to the metal with a clean paint brush, then apply paint to protect it from corrosion. Paint works well for iron and steel metals.Treat copper and aluminum with a wax or lacquer coating to protect the metal from rust.pply primer to the metal with a clean paint brush, then apply paint to protect it from corrosion.
