Here you have a huge collection of broken glass textures ready to be used in your Photoshop works. I have posted recently a list with glass textures that you might check. This one contains only broken glass texture, cracked glass texture, broken window texture and so on. If you need other types of glass texture check the other list. You can use a broken glass texture to create a broken glass brush for Photoshop and use it in your designs. Or you can use the broken glass texture to create a grungy old look effect. It can be used in many creative ways. You might want to take a look at one of my previous tutorials on how to create a broken glass text effect in Photoshop. You might try to create that effect using broken glass textures.
