Tall Handpotted Vase with Triple glaze? Shape C 10

My fab new handpotted vase, 240mm high, with that wonderful top

Would you call this triple glazed?

I can't quite get a clear photo of the hand incised number, it is so faint and filled with glaze, but to my eye, in direct light it says C16.

Here I tried a black & white photo, maybe a little clearer? It would fit with the shape of the C15 too I think.

Great piece!!

Its lovely & not instantly recognisable as CL like most handpotted are.

It's a wonderful piece sunny

It is so much nicer than the photo that was on TM and very unique!

That isn't a triple glaze effect, as it is a white glaze over a black and the reactive effect from the two glazes.

Could this shape be a C10 ? To me they look they same .....

Yes, it could, the impression is barely visible. I will change the gallery.

Ploughing through old Crown Lynn articles I came across this shape from a 1959 brochure!  So that gives us a time frame for this ware that has concentric lines on it.  The Brochure was headed Consolidated Brick & Pipe Investments Ltd, which were the precursor to Ceramco.
