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.

Very interesting video 


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  , 







The skill involved in such work

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

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.
