Nice looking bit of kit.
In my latitude (?), I have to make modifications to my melters. They are raised at the high end so that the glass is at about 45* to the horizontal and with the rainfall I have short legs attached to prevent the base from rotting.
In the past, I have used an upturned roof covered with a sheet of glass as a melter to clean an excluder. I had to watch the temperature, though. A slotted zinc excluder distorted with the heat.
