I don't think it was ever called chakra flow, though. Was it? According to the databook, Deidara mixes the clay with chakra, thus giving it explosive properties. The clay itself can be moved with chakra. So Deidara is basically doing the same as Gaara with his sand, only that Deidara uses explosive chakra. The clay itself is just clay, it was never even said to be Earth Release. And since Deidara only uses the earth sign when he infuses the clay with his explosive chakra, I think it's safe to say that Explosion Release is made up of Earth Release.

Also, as a side question, but Sasuke stated that he overloaded Deidaras bombs with electricity. Wouldn't that mean that they were loaded with electricity from the start?
