Traditional waffle irons are attached to tongs with wooden handles and are held over an open flame, or set on a stove. Most modern waffle irons are self-contained tabletop electrical appliances, heated by an electric heating element controlled by an internal thermostat. There are also two variants of the electric iron: one with removable plates and ones with non-removable plates. Professional waffle makers are usually made of cast iron whereas domestic models are often teflon coated. Many have a light that goes off when the iron is at the set temperature. Most modern waffle irons - particularly cast aluminum ones - are coated with a non-stick coating (e.g. teflon) to prevent the waffles from sticking to them. Cast-iron waffle makers are usually not coated and require seasoning like a cast-iron frying pan.
We are including a look at Table Broilers here because they are part of the "make it at the table" ethos that prevailed when electric appliances were relatively rare and consequently tres chic. Wealthy hostesses missed no chance to show off their shiny new appliances. In turn, companies like Manning-Bowman sold appliances that were more like chrome sculpture. When appliances became more commonplace, they were removed from the table and relegated to the kitchen.
That said, quite a few users say that this waffle maker isn't as sturdily built as previous versions of the same model, and that if you don't get the top heating plate aligned just right, it can fall off -- an injury hazard if the plate is hot. The top of the G48TD also gets very hot. Some use pliers to bend the metal clips that hold the heating plates in place, which helps them line up better -- or you can just use an oven mitt to protect your hands.
