Community-built Field-test Database for Patina Recipes
着色配方实测数据库的社区共建

社区配方库的价值在于把"人各一词"变成"数据可查"。共建规范：每条配方固定字段——试剂纯度、浓度、液温、基材牌号、前处理、暴露时间、封护方式，并强制附同批 50×50 mm 标准试片的 Lab 三点均值与 30 天室内老化照。互测机制：每季度征集 5 条新配方，由 3 名以上成员跨地域复测，比对偏差 ΔE > 5 的条目标注"结果依赖气候/水质"。数据用电子表格加版本号管理，注明贡献者与测试日期。实践表明，凡注明水质硬度与季节湿度的配方，异地复现率约高一倍。
A community recipe database turns anecdote into data. Fields are fixed per entry — reagent purity, concentration, bath temperature, substrate grade, pretreatment, exposure time, sealing method — each backed by Lab three-point averages and 30-day indoor aging photos of same-batch 50×50 mm coupons. Cross-testing: five new recipes per quarter re-tested by at least three members in different regions; entries with ΔE > 5 divergence get flagged "climate/water dependent". Manage the sheet with version numbers, contributors and dates. In practice, recipes that log water hardness and seasonal humidity reproduce about twice as reliably off-site.
