Royal Lancastrian / Mintons / Clews? - blue vase

This matt powder blue glaze looks right to be Lancastrian, and I think the base does too, but did they produce anything without the impressed mark? I know that other potteries like Bretby used a similar glaze. Pilkington's Lancastrian Pottery Society sell a booklet of recorded shapes but I come across the stuff so infrequently that's its really pointless getting it. Anyone care to propound their opinion on the vase, please?

Well your list of options is pretty big. Many companies produced vases like this around the 1920's. But all the main ones I can think off used impressed marks so even if the glaze was covering it you would see a trace. That includes Pilkington, Bretby, Moorcroft. It could be an unmarked bit of Morrisware who used a stamp but I think the chances are it is from the home of nearly all quality unmarked vases, China.

I can see the Clews thinking. The ones marked by clews I have come across are thickly marked and you would have seen it through pretty much any dirt. It raise the option that it is an unmarked English made vase intended for retailers who did not want a makers mark. But I have seen that shape in Chinese Celadon though and that leans me across to that being the origin.

It might be Mintons...

I think the photos make it look newer than it actually is - there's a good crusty layer at the base of the interior although that in itself, of course, is no guarantee of age. However, you can tell in the flesh that it has age, anything from 1910 to 1940, I'd imagine. I think that the Clews Chameleon attribution seems a good call, even down to the thick glaze around the stilt marks but the Mintons looks a good colour match too. I'll just write it off as another unidentifiable pot that'll end up back at the charity shop at some time. Thanks, everyone, for the suggestions.
