Through a simple and direct language, the podcast aims to be an educational space with a focus on products, applications and processes. The journey unfolds along the ceramic production lines. At each stage a topic. At each topic a critical issue. At each critical issue, when possible, a solution.","last_synced_at":"2026-06-12T16:18:11.208347+00:00","page_url":"https://stenobird.com/podcast/apparently-invisible-chemistry-in-ceramics-5864808"},"episode":{"title":"On black cores and degassing: analyzing a defect","slug":"on-black-cores-and-degassing-analyzing-a-defect","published_at":"2025-12-04T03:30:07+00:00","page_url":"https://stenobird.com/podcast/apparently-invisible-chemistry-in-ceramics-5864808/on-black-cores-and-degassing-analyzing-a-defect","show_page_url":"https://stenobird.com/podcast/apparently-invisible-chemistry-in-ceramics-5864808","url":"https://www.spreaker.com/episode/on-black-cores-and-degassing-analyzing-a-defect--68851793","audio_url":"https://api.spreaker.com/download/episode/68851793/zs_64_en.mp3","summary":"This episode provides a quick overview of the “black core” effect—an internal discoloration in porcelain tiles, typically caused by incomplete oxidation of the ceramic body due to trapped organic residues. It highlights the production conditions that make the defect more likely to appear and then outlines practical corrective strategies to prevent it. All in just ten minutes.","meta_description":"This episode provides a quick overview of the “black core” effect—an internal discoloration in porcelain tiles, typically caused by incomplete oxidation o…","key_points":[],"chapters":[],"topics":[],"duration_seconds":569,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/apparently-invisible-chemistry-in-ceramics-5864808/episodes/on-black-cores-and-degassing-analyzing-a-defect/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/apparently-invisible-chemistry-in-ceramics-5864808/on-black-cores-and-degassing-analyzing-a-defect.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
