The red body can be a decoration in itself, and it also looks good in combination with white, cream, transparent and contrasting glazes. The intense red body works well as a standalone colour accent, especially in minimalist pieces without full glazing.\u003c\/p\u003e\n\u003cp data-start=\"1189\" data-end=\"1450\"\u003e\u003csmall data-start=\"1189\" data-end=\"1450\"\u003eThe given parameters are approximate. The final colour, shrinkage, absorbency, and glaze behaviour depend on the kiln, atmosphere, soaking time, and firing curve. Before making a larger series, we recommend a technological test with the selected clay and glaze.\u003c\/small\u003e\u003c\/p\u003e","brand":"Witgert","offers":[{"title":"Default Title","offer_id":54394313310535,"sku":"W-16SF2502","price":49.9,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/2423\/0853\/files\/ChatGPTImage24lip2026-13-34-05-_1.png?v=1787957736","url":"https:\/\/alike.live\/en\/products\/masa-witgert-16-sf-25-0-0-2mm-red-10kg","provider":"Alike Pottery Studio","version":"1.0","type":"link"}
