Official Unit 2 Descriptive Passage

1: Which of the artefacts mentioned are the oldest?
2: When was the material Henshilwood found originally made?
3: What two common materials did ancient humans use to obtain their ochre?
4: What did the ancient people use to keep their ochre mixture in?
5: Nowadays, who makes use of ochre mixture?
6: Apart from painting, what else might ancient humans have used ochre for? 

The Blombos Cave discovery is the earliest-known example of a pigment- or paint-producing workshop. All of the materials were discovered at the same site, and they included in array of raw materials including samples of bone and charcoal, as well as pigment-producing equipment such as grindstones and hammerstones. Judging by the equipment, which shows signs of wear, Henshilwood and his team were able to deduce the process used to produce the ochre mixture. 
First, the pieces of ochre were rubbed on quartzite slabs and crushed to produce a red powder. This was combined with ground-up mammal bone, the traces of which show signs that it was heated before being ground. The ochre powder and the bone pieces were mixed with charcoal, stone chips, quartz grans and a liquid (perhaps water) and was then transferred to ablone shells to be gently stirred before being ready for application.

How pigment was made in ancient times.
A colourful 1.   was created by rubbing the ochre against pieces of quartzite.
Animal bones were 2.   and then crushed and added to the ochre.
The bones and ochre were mixed with other solids and the researchers believe  3.  was then added.
The mixture was poured into  4.  then mixed by hand.
The final mixture was ready to use for either 5. of walls or as an early type of  6. for the body.
