That is a tremendous amount of labor for a teapot. I've never seen an iron casting so thin.

Thanks for pointing out the video.

Interesting. Wish it had English subtitles.
Full of ideas, but slow to produce parts

Very interesting video  Thumbsup


Liquid iron is VERY fluid , so much so it was used to cast jewellery in the early 1800's  , very fashionable in Europe and some parts of North America . All started buy the death of a Prussian queen . 

Here are a few examples displayed in the Vienna technical museum  ,

Pretty amazing detail n those Rob.

I believe high phosphorous iron was chosen for thin / fine detail but it is exceptionally fragile, cracking with a characteristic white broken edge

I must have spent a good hour looking at those pieces , the detail is really outstanding Andrew  

High Carbon content  increases fluidity , no chance of machining it glass hard  Slaphead

That had to be made using the lost wax, or similar, casting technique.

The fourth pic from the top is a perfect example of what is known as a tree in lost wax casting.
