·    The EB1 readings are perhaps based on Kaufman-APMED.p541.pdfp541.#1:

 

GTz *pok
CHR	pok	v	lavar
CHT	#poc-o	v	lavar
CHL	pok	vt	lavar
TZE	pok	vt	lavar (+manos)

 

… with Spanish lavar = “to wash”. While this isn’t particularly many reflexes, the textual context – in connection with brushes – and the actual putative use of the ceramic object (in its time) make the EB1 reading extremely plausible.
