That nut grinder sounds like the same one my mom had when I was growing up.We have a vintage corelle plate that we use all the time. It's got a green vine boarder. When DH got his first place a bunch of people from his church gave him random things. Like one single plate.
I have a nut-grinder that you turn a crank handle on. the top is metal and orange and used to have flowers on it. the bottom is a glass jar. I grew up using it an it was passed on to me. But I'm not sure when I used it last; so my answer is the plate.
What pattern is it?The gas cooking stove I use is about 15 years old. I think that's the oldest thing in the kitchen.
My parents have got my great grandmother's wedding china in their kitchen. It must be well over 100 years old.
