How do they make the glass look all cracked inside?
At the flower shop I saw a beautiful glass vase that looked like it was all broken.

The crackle effect is made by dunking the piece in water while it is still hot, ~1300 F, then heating it back up to fuse the cracks back together and relieve stress. Another similar effect is the 'French Crackle' which is done be create a solid colored vessel, gathering clear glass on the outside, then applying a thin layer of opaque powder. The piece is heated until its pretty hot, dunked in water, and then blown out. The inner layer expands the cracks to show the opaque color underneath.

Not sure, but I think they cool it real fast causing it to crack. Either that or a real small hammer.
