I decided to make this variant shade of Burnt Umber after my observations of 16\u003csup\u003eth\u003c\/sup\u003e and 17\u003csup\u003eth\u003c\/sup\u003e  century paintings suggested this pigment had lighter and redder characteristics than those it assumed when manufactured in animal bladders. Raw Umber is calcinated to make the pigment, and the amount of Manganese Dioxide mixed with the Iron Oxide determines the range of undertones; my formulation is much warmer than is usual.\"\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e- Michael Harding\u003c\/span\u003e\u003c\/p\u003e","brand":"Michael Harding","offers":[{"title":"40ml","offer_id":48756212007141,"sku":"5060154040708","price":23.99,"currency_code":"AUD","in_stock":false},{"title":"225ml","offer_id":48756212039909,"sku":"5060154040685","price":101.39,"currency_code":"AUD","in_stock":true},{"title":"1000ml","offer_id":48756212072677,"sku":"372","price":343.89,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/8585\/5205\/files\/rawu_919a31e0-af75-419d-aaf9-c88507916321.jpg?v=1775631223","url":"https:\/\/seniorart.com.au\/products\/raw-umber-michael-harding-121-40ml","provider":"Senior Art Supplies","version":"1.0","type":"link"}
