Large copper pan (Clifton YO30)

Old copper jam pan 38cm diameter and 13cm deep. I don't think this has been lined and so it would not be suitable for cooking as the copper can leach into food or react with acidic foods and is toxic. I was going to use it as a planter but plants don't like copper either! If anyone has a use for this collection is from the Bootham/Clifton area. Thank you.
