Thanks Walt and Rose, but I think Walt is spot on. I have two of these pieces myself and the effect is the same. It is most certainly not smoke damage at all. Anita and I bought these pieces from the same seller. I didn't buy the owl because I already have a FM owl in the same design just a different effect. These pieces, as with most of the Moretti animals, are hollow with usually the feet glued on. My Moretti cat is hollow and you can see the hole in the bottom. The reason why so many are stumped when it comes to the effect of these animals is because they are newer pieces of Murano. You can really see the white spots Walt was referring to in the body of my crane really well. I will try to photo the spots on my crane and I will also post the bottom of my cat so you can visually see what I am talking about. Thanks again, Walt. Your insight was most helpful indeed and makes perfect sense now.
