The Mug

I was made from the hot glass of burning white snow.
I am something you cannot throw.
My writing is as black as a crow.
I am a liquid that moves very slow.
I come in many shades and can sometimes glow.
My replicas can be used in a show.
You can drink from me like a pro.
When you hold me I am like a warm hug.
Yes I am the best MUG.
