Who invented the ice water technique?

Dear readers please note : This is not meant to be a thread about Bubble bags and innovations, but rather I would like the focus to be on the question : Which region or who had the original idea for using ice water and ganja to make hash?

Was the simple ice water technique* invented in Afghanistan, Pakistan, India or in another hash making region many generations ago ..or was it first developed or invented by a Westerner in the 70's or 80's?

*no mesh screens are used, use a stick to stir ice, cold water and bud in a container, after 10 or 15 minutes stirring and a 40 minute wait for it to settle, most of the resin heads form a sediment on the bottom of the container, siphon off the water until an inch or so is left, then pour the remaining water and sediment through a fine cotton to catch the resin heads.
