This is just my experience and observations. Some time ago I bought a G3 off a guy from "the other site". On that same site there is a young man who had a lid custom made by GTP for his scuttle, so I stole his idea. My cousin is a novice potter, and she was sweet enough to take my scuttle to her shop and fashion a lid for it. It came out very functional. I think all scuttles should have the option to be fitted with a nice, dome shaped, lid. It does aid in retaining heat very well.
It also helps if you fill the inner chamber, and the actual bowl with water, and then put the scuttle the microwave for two minutes. By the time you get out of the shower, it is hot!!
