I start as earth beneath your feet, but mold me once, and a new forms you’ll meet.

I look like I could be a gerund for a verb of ability, but I am not. Before the refrigerator, I helped keep your food from rot.

You say iT one way, I say iT anoTher. WhaT am I?

You can find me in homes under bridges and on the facade of a certain convenience food seller.

I lie where life should perish fast, Yet in my bounds, green shadows last. A mirror born of desert’s sigh, Where weary feet and camels lie. What am I?
