It's a long shot but is it a game called Alchemy? I've been looking for a different old game called Alchemy and this one keeps coming up in the searches - you combine different elements to make different things as far as I can tell.

Apologies, I've never played it so not sure if it is exactly right. The comments suggest it used to be on Google Play but isn't any more.
