5 coloured pottery cones, what are they? and who by?

any ideas what these could be, no hole in the top like a pie funnel would have, maybe candle snuffers / christmas decorations. Look like French / British studio style, any ideas?
approx height 7cm / 2.75in each.

Don't look British to me and seem factory made but what for............. gnome hats?  

I've seen these in garden centres. I think people put the over the tops of canes for decoration or to stop them poking their eyes when they weed. 

they are all slightly different sizes and a bit irregular which makes me think they are not factory made. Cane toppers could be a possibility, they must have some age to them as they came with other pottery from the 1960's, and that was German, French and Norwegian!

the insides are hollow, white clay, no marks

I've seen them also in garden centres. You put them over canes or whatever to make a fairy-tale garden!

................ as if a gnome has come by and left his hat.




Not real gnome hats of course and probably made in China from the description of the inside.
