Vintage Clarks Pyramid Food Warmer

Didnt know what it is, so I googled to find following:
Antique white Ironstone panicking or warming jug from a Clarkes Pyramid Warmer, patented by Samuel Clarke in late Victorian, England
Used to warm milk, baby food or keep small portions warm over a specialised night light candle inside a metal food warmer stand
Features advertising and branding text for Pyramid Trade Mark Fairy & the characteristic Verse regarding Clarke's night lights.
It is out of my knowledge if it is really antique, cause of its amazing condition, but if you get a look to the last 2 photos I got of similar items out of internet, they look as good as mine.
2 last photos for price comparison as well.
I am happy enough getting 25 Euro for mine
