Geophysical survey by T Munnery of SCAU as part of the Wealden Glass Project. Two fields were investigated, and while an unequivocal location for a glassworking furnace could not be defined, the eastern of the two fields demonstrated significantly higher magnetic anomalies than the western. This evidence, coupled with the field name on the 1803 tithe map ('Glasse Field'), appears to outline the location of the glass furnace workings.
