grinding Roetel (Sanguine, red ferric hematite clay) from the last active German mining in Franconia. I use it for making watercolors, acrylic colors, inks. It cures pimples and mask acne within a few hours (no medical advice). The raw chunks can be used for drawing. #roetel #rouge #hematite #ferricclay #earthpigments #sanguine #troschenreuth #deffnerundjohann #redochre #ironoxide #clay #farberde #onerde #rotetonerde https://www.instagram.com/p/CNSdOB-Hwbq/?igshid=1didekrlzoaf7

new experiment - making a Juassic limestone primed canvas I used a milled limestone mixed with ferric limestone clay I collected from the old quarry at my hometown. The pure ferric clay/limestone granulate I collected doens't work, it contains too much clay, the result is too smeary. But the chunks of pure limestone from the quarry would be to hard to process with my equipment in the quantities I need it. So I bought milled pure limestone which is used as an add on in animal feeding. The color of the pure milled limestone is too pale for my purpose. Now together with the yellow limestone clay it works well as a primer. I also added volcanic ash. First test show it is possible to draw with a fountain pen on such a canvas. #experiment #abstractpainter #limestone #jurassiclimestone #ferricclay #limonite #ironore #canvaspriming #watercolorcanvas #earthpigments https://www.instagram.com/p/CMXR8Hkny26/?igshid=1u0upjtcp1faw

method for making burnt iron oxide pigments tested today at a barbecue burnt pigments made from yellow Jurassic clays and bean ore clay from souhthwest Germany (on the right side the original colors) #burntironpigments #earthpigments #ferricclay #laucherthalgelb #beanore #bohnerz #jurassicclay #jurayellow #limestone #laucherthalorange #bohnerzlehm https://www.instagram.com/p/CA1PJpMHeeO/?igshid=1v82xvt4qi4oa

starting a new painting, using multicolored mudstones found at the ice age moraine, Moroccan red ochre from Kremer Pigmente, charcoal, Roetel (Sanguine) and pens made from yellow ferric clay from my home town. Sometimes a piece will chip off from the mudstones, but that's no big problem. The lines drawn with the Roetel, the ferric clay and the mudstones can be washed with water easily. After drying, watercolors, acrylic colors and lacqeur colors can be used on the painting. #watercolorjourney #mudstones #naturalpens #earthpigments #ferricclay #sigmaringendorfgelb #moroccanochre #redochre #roetel #sanguine #charcoal #abstractpainting #paintinginprogress #ancientcolors #earthcolors #kremerpigmente #morainestones #lehmsteine #ironoxidepigments #ironoxides https://www.instagram.com/p/B3QqNaOnJSC/?igshid=1mwugacuosxd9

got some samples of Virginia ferric clay from a facebook ftiend today. Interesting to see how similar one of the clays is to the ferric clay from my hometown in southwest Germany. #ferricclay #earthpigments #earthcolors #virginiaclay #ironoxides #ironpigments #limonite #virginiaorange #laucherthalorange #acryliccolors #handmadecolors #handmadeacrylics https://www.instagram.com/p/B3OXl3jINuM/?igshid=g2l0bf5f9m6e

excited about a new iron oxide pigment. Roetel (sanguine, red chalk) from Kremer Pigmente. Raw pieces can be used for drawing onto.paper. The lines can be easily washed with water. Drawing onto wet paper is also possible, and the pigment makes a very good ink. I think it is kind of a ferric clay containing mostly hematite. But it has a slightly orange tone, other than the deeper reddish hematite ochres . Maybe there is some limonite present in the Roetel additionally. It might be possible to make pens by filling axwatery paste of the Roetel into thin sticks of hollow cane, reed or bamboo. #roetel #ironpigments #earthpigments #ironoxide #ferricclay #hematite #redclay #redchalk #sanguine https://www.instagram.com/p/BzHrcUfI5UY/?igshid=1ogs0r38z7h4t

digital photo manipulation and painting of a photo of a Neanserthal cave in Veringenstadt, southwest Germany. A few days I found gold ochre neat the town. Meanwhile the clay has dried, and today I made watercolors and inks from it. #ochre #earthpigments #göpfelsteinhöhle #ferricclay #limonite #handmadewatercolors #digitalpainting #imagemanipulation #neanderthalcave #aurignaciencave https://www.instagram.com/p/By_rgSuo_wo/?igshid=1lqzj8a9rz1b9

burnt the yellow ferric clay / ochre I had collected today, using a small hand torch for a few seconds. I turned reddish brown, same color as the Moroccan ochre from Kremer pigments did, which is labelled pigment yellow 43. I burnt this one also for comparison. Result: the ferric clay (yellow bean ore clay) from the Jurassic linestone hills at the Lauchert and Danube rivers in southwest Germany contains most likely pigment yellow 43, which is hydrated Iron oxide, Limonite. wikilpedia:Yellow ochre, FeO(OH)·nH2O, is a hydrated iron hydroxide (limonite) also called gold ochre. #beanore #ferricclay #yellowochre #bohnerz #bohnerzlehm #lehm #gelberocker #limestoneyellow #juragel #jurassicsea #jurassiclimestone #jurassicsediments #erzlehm #earthpigments #watercolors #handmadewatercolors #pen #claypen #lehmstift #lehmfarbe #ironoxide #ironpigments #limonite https://www.instagram.com/p/ByzEGY1IpPO/?igshid=1af786mkq24u
