Or as I personally call them, "Clay Kaboomables", derived from Crucible + Kaboom. Also includes a new item, Bomb Fuses, along with a recipe to use them for standard Ore Bombs. Fuses can be made with Twine or Rope, Twine giving you 16 and the easy to find Rope giving 8. 

I would of course like to see this expand into laying long fuses on the ground to detonate many bombs at once. Not sure if I can pull that off without learning C#, but I hope to see this become the catalyst for such an item.
