Unverified锅径越大导热越难均匀，尤其在家用单一火眼灶上；大锅面需要更厚的锅体（碳钢≥2mm、铸铁≥3mm）来靠蓄热弥补火力分布不均，薄锅大径必然中心热边缘凉86% similarUnverified石英管加热的多士炉预热快但边缘易过焦，选择双面各2根加热管（共4管）以上的机型可显著改善单面加热不均问题79% similarUnverified发热管数量：4管（上下各2）比2管加热更均匀，做大批量或对上色要求高选4管以上；单纯烤箱内壁反光不锈钢也有助于受热均匀78% similarUnverified铁锅越重越耐用越蓄热，但操作费力；轻量化熟铁锅好上手但薄壁易变形，追求耐用和红烧焖炖选重锅，追求灵活翻炒选轻锅78% similarUnverified铸铁锅蓄热强但升温慢，燃气灶用中小火即可，全程大火易导致底部食材焦糊而侧壁未热；这与其厚壁导热特性有关而非火力不足78% similar
