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

bean iron ore colors I have 4 different kinds: 1)ore from my hometown Laucherthal, southwest Germany 2) ore from Otranto (Kremer pigments) 3) ore from the Swabian Alb, southwest Germany (Kremer pigments) 4)ferric bean ore clay Laucherthal I thinkbthe bean ore from Laucherthal contai s high amounts of Manganese oxides, thus the more Umber like color. The swatches were made using water and pigment only. Pigments I collect myself I prefer keeping in a rather coarse state in jars, so later when I make colors from them I can still decide if I want to grind the pigment to a finer state. Often I like using the more coarse pigments, because they add strucure to my abstract paintings. #handmadecolors #handmadewatercolors #beanore #bohnerz #limonite #goethite #earthpigments #kremerpigmente #ironore #ironixide #erdfarben #erdpigmente #ferricclay #laucherthal #laucherthalbraun https://www.instagram.com/p/CAybcqKAbj5/?igshid=1xs2g4zyyigou

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
