𝗣𝗼𝘁𝗮𝘀𝗵 𝗙𝗲𝗹𝗱𝘀𝗽𝗮𝗿 𝘃𝘀 𝗦𝗼𝗱𝗮 𝗙𝗲𝗹𝗱𝘀𝗽𝗮𝗿 — 𝗧𝗵𝗲𝘆'𝗿𝗲 𝗡𝗼𝘁 𝗜𝗻𝘁𝗲𝗿𝗰𝗵𝗮𝗻𝗴𝗲𝗮𝗯𝗹𝗲. 𝗛𝗲𝗿𝗲'𝘀 𝗪𝗵𝘆 𝗜𝘁 𝗠𝗮𝘁𝘁𝗲𝗿𝘀.
Same mineral family. Very different behaviour in your kiln.

⚗️ 𝗣𝗼𝘁𝗮𝘀𝗵 𝗙𝗲𝗹𝗱𝘀𝗽𝗮𝗿 (𝗞-𝗙𝗲𝗹𝗱𝘀𝗽𝗮𝗿 | 𝗞𝟮𝗢 𝟭𝟬–𝟭𝟮%) → Melts at ~𝟭,𝟮𝟬𝟬°𝗖 — higher, more controlled melt → Produces a 𝘃𝗶𝘀𝗰𝗼𝘂𝘀, 𝘀𝘁𝗮𝗯𝗹𝗲 𝗴𝗹𝗮𝘀𝘀𝘆 𝗽𝗵𝗮𝘀𝗲 — lower deformation risk → 𝗕𝗿𝗶𝗴𝗵𝘁𝗲𝗿, 𝗰𝗼𝗼𝗹𝗲𝗿 𝘄𝗵𝗶𝘁𝗲 fired colour — preferred for whiteness-critical products → Lower thermal expansion → 𝗿𝗲𝗱𝘂𝗰𝗲𝘀 𝗴𝗹𝗮𝘇𝗲 𝗰𝗿𝗮𝘇𝗶𝗻𝗴 𝗿𝗶𝘀𝗸 → 𝗕𝗲𝘀𝘁 𝗳𝗼𝗿: Sanitaryware bodies, porcelain tableware, whiteware, high-whiteness tiles, fine china

⚗️ 𝗦𝗼𝗱𝗮 𝗙𝗲𝗹𝗱𝘀𝗽𝗮𝗿 (𝗡𝗮-𝗙𝗲𝗹𝗱𝘀𝗽𝗮𝗿 | 𝗡𝗮₂𝗢 𝟴–𝟭𝟭%) → Melts earlier, flows more freely — 𝗮𝗴𝗴𝗿𝗲𝘀𝘀𝗶𝘃𝗲 𝗲𝗮𝗿𝗹𝘆 𝗳𝗹𝘂𝘅 → Higher thermal expansion — 𝗴𝗹𝗮𝘇𝗲𝘀 𝗰𝗮𝗻 𝗰𝗿𝗮𝘇𝗲 𝗮𝘁 >𝟯𝟬% 𝗰𝗼𝗻𝘁𝗲𝗻𝘁 → Produces a 𝘄𝗮𝗿𝗺𝗲𝗿, 𝗰𝗿𝗲𝗮𝗺𝗶𝗲𝗿 fired tone — not ideal for bright-white requirements → Brighter glaze 𝗰𝗼𝗹𝗼𝘂𝗿 𝗿𝗲𝘀𝗽𝗼𝗻𝘀𝗲 — works well with certain colorant systems → 𝗕𝗲𝘀𝘁 𝗳𝗼𝗿: Glossy glazes, frit formulations, fast-fire floor tile glazes, coloured glaze bodies
