You've heard me rave about the Liquid Mirror before, so I won't give you that spiel again (let's just say that a bottle this big is a pretty extravagant gift). But the Sludge is one of the smarter products I've heard of - basically it's comprised of the leftover gunk from the normal paint-making process. Leftover gunk (both solid and liquid waste) that would otherwise have to be disposed of somehow. You can read more about it here, but it's a pretty impressive and ecologically-friendly product.
Thanks, Rheni. I'll try to use it wisely.
