THAT IS BEAUTIFUL!

In the 'before' picture it looks like you had 2.25 inches of soil in the jar. The floating stuff is organics, and that's good. After 2 minutes you see 2 inches of settled sand/gravel. 2 inches divided by the 2.25 inch total gives you 89% sand/gravel. Then after 2 hours you had 0.25 inches of silt. That's 11% of the total. That leaves nothing for clay, which by the looks of the clearish water on top is what you have. Again the floating stuff is good ol' organics.

How much soap did you put in the jar? Looks like more than a few drops.

Nice counter tops!

Just a couple drops I thought lol wasn't much. I had alot of dirt brought in when I moved to build a pad for my mobile home, was worried it was clay because it was so hard. I took samples all around my yard mostly around where I brought dirt in, getting a soil test done now. hopefully getting grass started won't be as hard as I thought.
