后台常收到使用与定制层面的小问题，单条回复容易漏细节。这三个问题的答案，核心都落在一句判断上：材料有自己的脾气，顺着养，逆着坏。今天把出现频率高的三个一次答清：银饰能不能戴着洗澡洗手，家用编织选竹编还是藤编，非遗手作能不能刻字改尺寸。都是小问题，也都是真问题。所谓氧化变黑，是指银与空气及水中的硫化物反应、在表面生成硫化银薄层的过程，属银的正常化学性质。竹编（青神竹编）2008 年列入国家级非物质文化遗产名录（来源：中国非物质文化遗产网）。
Small practical questions about use and custom arrive often in the message box, and quick replies drop detail. The answers to all three turn on one judgement: materials have their own temper, kept well when humoured, spoiled when forced. Today the three most frequent are answered together: may silver be worn in the shower, should home use choose bamboo or rattan, and can handmade pieces be engraved or resized. Small questions, real ones all.So-called tarnishing is the reaction of silver with sulphides in air and water that lays a film of silver sulphide on the surface, an ordinary chemical property of the metal. Bamboo weaving (Qingshen) entered the national intangible heritage list in 2008 (source: China Intangible Cultural Heritage website).
问 ｜ 银饰能不能戴着洗澡洗手
Can silver jewellery be worn in the shower or when washing hands?
答 ｜ 偶尔碰水没关系，长期泡水不建议。洗手溅到及时擦干即可；洗澡时的热水、皂液与含氯水分会加速银面氧化发黑，温泉与海水尤甚。做旧工艺的银饰保养更忌反复浸水，发黑不均会破坏原有层次。日常摘下收好，是最省心的做法。
Occasional splashes do no harm; long soaking is discouraged. Dry promptly after washing; the hot water, soaps and chlorinated water of a shower speed the tarnishing of silver, hot springs and seawater worst of all. Antiqued finishes are the most vulnerable, since uneven darkening ruins the intended layering. Removing it daily is the easiest care of all.

问 ｜ 竹编和藤编，哪一种更适合家里常用
Between bamboo and rattan weaving, which suits daily home use?
答 ｜ 各有长处，按位置选。竹篾细腻挺括、造型精度高，适合收纳筐、托盘、茶器配件这类案头用途；藤条柔韧耐折、坐感舒适，适合椅凳、灯罩等大体量家具。干燥的北方重点防竹丝开裂，常上蜡少暴晒；潮湿的南方重点防藤条霉变，保持通风。看用途再看气候，答案就定了。
Each has its strength; choose by position. Split bamboo is fine and crisp, holding precise form, right for desk-side use as trays, storage and tea accessories; rattan is pliant and resilient, comfortable to sit on, right for chairs, stools and lampshades. In the dry north guard bamboo against cracking, waxing often and shading from sun; in the humid south guard rattan against mould with steady airflow. Use first, climate second, and the answer sets itself.

问 ｜ 非遗手作能不能刻字或者改尺寸
Can handmade heritage pieces be engraved or resized?
答 ｜ 分材质分工艺，要逐件问。银器、竹木这类可再加工的材质，刻字改尺寸通常可行，但须由匠人本人或经其确认的工坊操作，外来的改动容易伤结构；漆器、织绣、瓷器这类成品后几乎不可逆的工艺，一般不建议改动，改了等于破坏原作。定制意愿在购买前提出，能不能做、加多少工费，让做这件东西的老师说了算。
It varies by material and craft, piece by piece. Silver, bamboo and wood admit reworking, so engraving and resizing are usually possible, but only through the maker or a workshop the maker approves; outside alteration risks the structure. Lacquer, embroidery and porcelain are all but irreversible once finished, and altering them amounts to damaging the original. Raise custom wishes before purchase; whether it can be done and at what cost belongs to the maker of that very piece.

问 ｜ 头一次买非遗手作，韵和鸣建议怎么选
For a first handmade heritage purchase, what does YUNHEMING advise?
答 ｜ 三条：看用途，日用选趁手的器物，送礼选有故事的品类；看养护条件，先了解这类器物怕什么，潮、晒、磕碰各不相同；看来源，选能讲清出自哪位匠人之手的真作。使用、保养、选品的学问我们会持续在「答疑录」里讲，器物买回去，服务才刚开始。
Three rules: by use, choose handy pieces for daily service and storied categories for gifts; by care, learn first what the material fears, damp, sun or knocks; by source, choose works whose maker can be named. The lore of use, care and choice continues in this column; the service begins when the piece reaches your home.
