I thoght i would post some of my odball science projects - just in case peoples are interested in the stuff that a moistly retired man with endless scientific curiousity and a smidge of Asbergers syndrome does for funsies.
So let us begin. Clay has been a recent activity, collecting bits of it, suspending it in water, letting the sand n silt settle out and pouring off purified clay. Then i flocculate the suspension with 2cc of milk per liter stirred into the suspension, followed by a simalar ammount of saturated aluminium sulphate solution, causing the clay to clot and clump together(flocculate) and sink
to the bottom. I add paper pulp for extra tensile strength and plasticity and sometimes some (bentonite) clumping cat litter if it lacks plasticity. i add a little organic matter (flour or sugar and a smidge of fixed nitrogen) and let the microrganisms colonise it for a week or four, which seems to improve the way it handles. then i do some pottery - See below, from my “cartridge in a bare tree” posting on my coil swingers/show and tell/todays wasteland finds.
Todays other thing.
We had a 2 liter of milk which went slightly odd, it kept threatening to clot every time i steamed it for coffee. So i ended up adding hot water and a litttle vinegar and making cottage cheese/casein. Here is a photo of it drying…
