Hi,
Sorry but, what is a tinnery ? Have you a synonym ?
I look on translation's plateformes and don't find anything...
A tinnery is also called a cannery - a place that cans food products. There's one for protein, grain, veggies and fruit. Once you are producing tin (used to build a tinnery and needed for canning), they are a great way to increase food. Tinned food is good for trading too since they are worth more than the cost to make.
