I can lie, but I cannot speak. People use me to welcome and clean.

Pronounced as one letter, and written with three, two letters there are, and two only of me. I’m double, I’m single, I’m green blue, brown and gray, I’m read from both ends, and the same either way.

My first half sizzles and crackles with heat, My second is gone, or a truth you repeat. Join them together, the story is plain; A fire snuffed out and a tired brain.

I am deadly to consume, but you may find me in a traditional home. when a certain skeleton saw me in this traditional way he became perplexed, what am I?

I am brown and sweet and melt in heat. What am I?
