From my father's collection, 5 & 6

South American whistling pots.
This one originates in the Chimu culture of Northern Peru. 
It's a double -flasked vessel joined in two places and, if you know how,  you can make different sounds by tipping the water it holds this way and that. The sounds resemble the calls of birds and animals, and of other natural noises. 
There's a short video of these jars being demonstrated here and it's totally  captivating -  do listen.

(More technical  stuff about whistling jars here.)

The Chimu people lived in the Andes around 1000 years ago  and  it's not entirely clear how they made this black pottery. 

 "According to one theory, Chimu potters closely regulated the temperature and oxygen level in their kilns. This allowed them to reduce the oxidation of the pottery, producing its blackened colour. Another theory suggests that when the kiln reached its highest temperature it was completely covered with soil, stopping the oxidising process while promoting the effect of smoke and soot, both of which enhanced the black colour."


How old this particular pot is I have no idea because clearly they continued to be made and are still sold today.  (Anthropologists in my time were sniffy about 'airport art' created as souvenirs instead of 'the real thing'  but that's a typical example of cultural bias: why not make money off tourists just as conquerors and colonists have exploited indigenous people.)


The other jar (in extras) I know nothing about. I'm pretty sure it's also from South America and it whistles if you blow across the hole in the top.  (Oh - maybe you could hang it up and let the wind do the whistling?)
I like its minimalistic human features and it has a cute little face which you can see in the second extra image.

I was delighted that Tivoli was inspired by my yesterday's blip to see if she could create the same paper pattern as appeared on the Moorish bottle, which she did with great success here.
