I have a "gadget" currently on ebay - a 4-section "pipe tin" or round loaf pan, obviously used, and I so state.
Instead of posting a question I got a rather convoluted private question about the uses for it.
So, if one sees an ad for a bread pan (or cake, if one is an expert) that forms the shape when the dough rises into the top part,
WHY WOULD someone ask if it could be used as a JELLO MOLD???
I have been puzzling over this one since early this morning. I answered, no it was not suitable for a Jello mold. I'm not even sure it would hold a liquid. I have baked pound cakes and sponge cake in it but I've had a fair amount of experience knowing how much these cakes will rise. Then I thought, why does anyone want to make a Jello log? I asked but the questioner has not replied.
