In the early 1950s, Henry Moore and some of his assistants, including Anthony Caro, constructed a small foundry on the left-hand side of his garden at Hoglands, Perry Green. It was used to create lead and bronze sculptures, although the works he cast here have not been identified.

At one period of my career I thought I ought to know how bronze casting was done, and I did it myself at the bottom of the garden, along with my two assistants. We built a foundry in miniature of our own, and throughout one year I cast some eight or ten things into bronze. The experience was very valuable, but I now get all my casting done by long established bronze foundries with generations of experience in the work.…

Anthony Caro, interviewed by Michael Phipps in 2006 explained why the foundry was not maintained:

We couldn’t get the foundry working very well because in fact we made it a bit too big for the crucible, so you used to fill it with coke and then the coke would get red hot and by that time it would go down and you would have to put more cold coke in and so then the bronze would solidify again. 

It was very difficult to get it right and we had a big bellows and we used to pump that bellows until 2 o’clock in the morning trying to get it hot enough to pour. It was very amateur, and in those days they didn’t have blowers like they do it now, but we cast an interior/exterior form which wasn’t bad, about 2 foot long, a reclining one, and I also put two of mine in there and Alan [Ingham] put one of his, and we were all doing it together and it was very nice… In the end the time it was taking was too long and we were having too many failures....
