Sweating and finding stinky throughout the flames, they found they could attain high sufficient temperatures to sort beads in more compact fires than These typically related to glasswork. These tiny fireplaces may are actually missed by previously excavators, Hodgkinson suggests, so Most likely glassworking was fewer exceptional than scientists have normally assumed. Possibly Girls and kids have been also involved, Hodgkinson speculates, reflecting on the various hands expected to take care of the hearth.
