Pottery Shards

As we walked along the lake shore of a nearby reservoir, we came across an eroded bank. Discards from a farm or home that had once been nearby had been exposed by the erosion. There were pieces of rusty metal (some of you altered jewelry or sculpture artists probably would have salvaged this, but I did not) glass, clay tile, pottery shards, and other things. I brought home a few pieces of pottery that still had bits of pretty glaze on them. I don't know what I'll do with them...any ideas? And what type of adhesive could I use? I would be interested in your comments and suggestions.
