Here's the straw-coloured Ambrico handleless mug Brian Ronson gave me on Saturday. I had expected it to match my straw-coloured NZR shard, but it does not!

73mm H x 80 OD top x 50 OD footring


It is measurably smaller, being closer in size to the white NZR shard, but larger than the latter and thinner in body than both, by 1mm.

75mm H x 83 OD top: 73 x 80 x 50 OD footring: 71.5 x 77 x 48

While the dimensions place it between the different NZR shards in size I think the thinner body would make it a later piece.

75mm H x 83 OD top: 71.5 x 77 x 48 OD footring: 73 x 80 x 50: ditto
a possible chronology

I now see it as a size and shape match for my similar straw cup, also shown above, which has an early block handle. This leaves only the other block handle cup, gloworm's one, to compare ... until I find more!

Also of interest in this discussion is the vitrified Ambrico US Navy handleless mug. I have photographed that in comparison with the new earthenware cup to show that while they appear to be the same shape, the size difference is huge, and unless shot side by side (as in the first three rows) they appear to be the same (bottom row).


As the Auckland Museum files do not record sizes I relied on other distinctions, specifically the relative body thickness, but more obviously the NZR stamp, to distinguish NZR beaker K3905 from US Navy beakers K3910, K5045, and K6357.

This appears to be an insulator cup Jeremy ....

Appears but is not.

Ambrico, straw-coloured earthenware. Pre-1948.

Even smaller than the smaller (of two sizes of) vitrified insulator cups from the 1960s.
