(I guess it's been mentioned before, but ) that there are likely to be factories currently producing 'annagroen' (uranium green coloured) bowls, jugs and dishes.
I've seen so many similar ones on the markets recently. The colour can be very deceptive in sunlight (less so under artificial light and not at all under UV), and just came back from Berlin where we saw several more very suspect items.
The first few times I thought they might be 1955 or so, when the factories were trying to replace the uranium green that had by then been prohibited. But I'm increasingly forced to the opinion now that they are just plain 'new'!
Apart from anything else, they were all too clean to be pre 1950 which would otherwise be the assumption for Dutch/German/Belgian factories. No erratic micro-scratches at all! (etc)
Generally they seem to be designs which are 'as generic as possible'.. a few geometric curves or a few optics on a basic shape. I have NOT seen one which I could give a particular factory or pattern to.
One day soon I expect to walk into the right store and find a whole collection of them sitting there. But Ivo might find the outlet first!
I won't be the only person who has 'lapsed' into the habit of 'trusting' the colour alone. It's probably wise to be doubly vigilant!
Ivo. please comment!
