Query: cast iron kettle

this is a good product but at first we didnt notice any water evaporating. we have to slide the lid off the top to make sure that it evaporates more. Our living room isn't that large but it is still very dry and staticky. we can't however put it directly onto the top of the stove and have it on a trivet. We tried to put it right on top of the stove when we first got it and it left marks. Maybe if we had it right on top and not on the trivet we would notice the water evaporating more quickly? not sure...
