Is this a 1629 salt lurking here?

The Expo photos on the forum show a salt shaker lurking behind a glass:

There is a clearer photo here:

(I also see a toothpick holder!!!!)

Being expo ware I guess this one would be in the Aquamarine glaze.

Is it a 1629?

100% correct Jeremy they are the 1628/29 Insulator Salt and Pepper
I didn't notice any toothpick holders in the records ......

Well it looks like a toothpick holder doesn't it?

If it is the same Aquamarine glaze, which you have established is a high fire glaze, then we should expect it to be a vitrified item, which means 1600s, maybe 3600s.

Maybe it's not described as such.

The shape of the Insulator Salt and Pepper is consistent with the tea, coffee, and water pots 1616 thru 1620, and also with the Aquamarine casseroles and so on, 1644-1647 etc.

The Expo cup and saucer, on the other hand, is Shape 25 (or similar) so the "toothpick holder" may alternatively be that shape.

Unfortunately the holder is a bit buried in the pic and we can only see the top. The shape might be either, but vitrified (?), as indicated by the glaze.

An afterthought is that little "mustard pot" or hotel sugar bowl that is not the Cook & Serve one but matches the 1616-1620s in shape. I forget whether we found a number for that on not.

Although they certainly look like toothpicks they may be tubes of sugar.
