Thread: Few new stones..anyone recognize them?

I picked up a couple of stones today because they were for little money but not like anything I typically see or buy. The small square one looks to be wood almost but used a knife on it and it's a stone of some sort. Very light like driftwood almost. The larger square piece feels almost the same and still very light for a stone. Doesn't shave off as much as other one.. The smaller rectangle looks like possible washita but also feels lighter. The larger rectangle seems harder heavier and smooth.

Hard to say from the photos, the 3rd may be an ark.

Wash them up with oven cleaner and simple green, you may have a couple keepers there.
