Here, I have added it to the G1947U transparent base. It produces green celadons at low percentages. Still transparent where thin, 5% is producing an amber glass (and the iron is showing its fluxing power). 7% brings opacity and tiny crystals are developing. By 9% color is black where thick, at 11% where thin or thick - this is “tenmoku territory”. 13% has moved it to an iron crystal (what some would call Tenmoku Gold), 17% is almost metallic. Past that, iron crystals are growing atop others. These samples were cooled naturally in a large reduction kiln, the crystallization mechanism would be much heavier if it were cooled more slowly.","brand":"Synapse","offers":[{"title":"Default Title","offer_id":35160812191789,"sku":"","price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0016\/9017\/3485\/products\/catkymibab-400W.jpg?v=1613407485","url":"https:\/\/flying-mate.myshopify.com\/products\/the-multitude-of-things-iron-oxide-can-do-in-reduction","provider":"Synapse","version":"1.0","type":"link"}
