Fusing an anvil'd item

[Thiefy]

Ok so I have those specs which are fused with traveler's wing glasses:



My questions are:
1. What will happen if I fuse it (as the "appearance") to another "clean" item?
2. What will happen if I fuse it (as the "appearance") to another item which is fused it self? will the new appearance come over the old one?

Thanks!

In both cases, the new item will look like Traveler's Wing Glasses.
