Did some #ceramic prep work today I'd been putting off. We have some white clay & red ochre that I needed to process for natural slips & paints to apply to our #ceramics. I by no means processed as much as I'd like, but it was a start. 1/ #archaeology #pottery Lumps of white clay & red ochre on white paper.
The white clay, 1 of 2 we've found in the past few years, isn't ideal, having some small quartz & chert pea gravel, grit & course sand in it. I selected several small pieces after breaking up the main mass. 2/ #ceramics #archaeology #pottery Lumps of white clay & a gray quartzite hammerstone sitting o
The clay crushed nicely, except for the screeeech! of quartz grit dragging across the grinding stone surface. I picked out most of the grit & sand, but it will need sieved. The entire batch probably should be liquefied, then drain off the clay. 3/ #ceramics #archaeology #pottery Powdered white clay & gray quartzite hammerstone sitting on
Next came the red ochre (with a little yellow, too). There was a lot of red ochre nodules in the load of red clay we got after Hurricane Ida. 4/ #ceramics #archaeology #pottery Lumps of red ochre with some yellow ochre mottles & the gray
Initial crushing showed that some areas of the ochre lumps were a lot harder than others. These took careful pounding with the end of my hammerstone, rather than the normal rocking back & forth. 5/ #ceramics #archaeology #pottery Initially crushed red ochre & the gray quartzite hammerstone
More work than I anticipated on both the white & red, but that's often the case. 6/ #ceramics #archaeology #pottery Powdered red ochre & the gray quartzite hammerstone sitting
Not a bad yield for 3 ochre lumps. Mixed with a little base clay & applied as a slip or paint, this with fire out a nice orange-red to dark red. I would have processed more, but the evening breezy picked up! 7/ #ceramics #archaeology #pottery Area of powdered red ochre on the metate.

The slip clays will be used for decorations such as this Nodena Red-&-White bottle or this Southwest-style bottle. On these, the slips are rubbed with a smoothing stone to merge them with the moist clay body. 8/ #ceramics #archaeology #pottery 2 views of a reproduction globular Nodena Red-&-White bottleSquat, subglobular bottle with slightly flared neck & rounde

The only gold I've found on archaeological surveys/excavations was a melted 0.13g lump on an army base. It was in an historic trash burn, so prob. lost jewelry.

The army wanted to send 2 MPs to the Lab to guard it until transfered to their curation facility. It was worth $54.
Actually, that was incorrect. They wanted MPs to guard it 24/7 until it could be transferred to Fort Knox (of course). The boss finally convinced them of how tiny it was, but they still demanded it be stored in the firm's safe until a military courier could be sent to pick it up.
It get's weirder. Melted ruby-flashed colorless glass in the shovel test, as well as other burned artifacts at an old rural house site, proved it was a piece of jewelry that accidentally got in the trash. The army forbid us to include a site map in the report & redact the...

I've seen people say that archaeologists' communication skills are not the problem with the growing popularity of pseudoscience.

I mostly disagree.

Were you at the "public invited" archaeology conferences in the 1970s to early 1990s?

Did you hear the public comments? 1/
The comments about "Interesting topic, but I wish I could've understood what he was saying." Or, "I should've brought a dictionary." And, "Why do they have to talk like they're walking thesauruses? Can't they speak plainly?" 2/
What about the comments about how aloof & condescending a lot of academia archaeologists are when you ask them a question? Like everybody should know the answer.

Were you there when university anthropology departments frowned on & in some cases forbid public engagement? 3/
