Need help dating these pieces!

It's not glass but I figured pottery was in the same category. If not, mods can move it or delete.
I found all of these at a site that dates back to the 1750s.
I've found blue and green feather edge pottery before and believe it dates to the 1700s. If some one can narrow this down, it would be greatly appreciated. The rest I need help with. Also any dating on the pipe stem?

Thanks for looking!

I'm no expert here. But to me the shards look like stuff I find commonly in old toc dumpsites. If I had to put a guess out I would say mostly 1830s-1880s. Clay pipe stem is probably mid to late 1800s. Just a guess!

I find these shards all the time it's hard to tell the age I find these type of shards in all kinds of dumps ranging from early 1800s to turn of the century. I would love to find a complete one.
