描金与贴金，差在哪里

▍一、描金：用笔"画"出来的金线

描金所用的不是箔，而是调出来的"金泥"——把金粉与胶（漆器上常用漆作粘合材料）调和成可以用笔蘸取的稠状物，再照着画稿运笔。它的本质接近绘画，所以能做出极细的转折、提按和顿挫，一根衣纹可以细到像发丝。

代价在于速度与留痕。用笔画，慢；画错了难改；久用之后，金层若没有罩漆保护，磨擦多的位置会先发暗。

▍二、贴金：整片"铺"上去的金色

贴金走的是另一条路：先在器物上髹一道专门的粘合层，待它处在将干未干的状态时，把极薄的金箔覆上去，用软工具压实、扫平，再扫去没有被粘住的多余部分。

这道火候最难拿。粘合层太湿，箔会浮；太干，箔粘不牢，日后容易起翘脱落。贴金的优势在于成片：大面积的金地、金背景、金批文字，用箔比一笔笔画快，也更容易统一光泽。

▍三、一眼能看出来的三个区别

头一个是形态：描金是线，有笔意，粗细随走势变化；贴金是面，成片发光，边界常常能看见箔与箔交接的细路。第二个是厚薄：金泥堆出来的线条是立体的一笔，用侧光看有厚度；箔极薄，贴合后几乎平伏于器物表面。第三个是工序位置：贴金要专门打一层粘合层并等它到火候，描金则直接进入"画"的阶段。

需要说明的是，这两法并不互斥。不少器物是先贴金地、再在上面用他色描绘纹样，两种做法在同一件东西上叠着出现。

一句话概括：描金出线，贴金出面；一个看笔意，一个看火候。

In one line: tracing produces line, leafing produces surface; one is judged by brush feeling, the other by timing.平遥推光漆器的常见工序说法里就有"描金彩绘"一项，讲的正是以笔取线、以彩取面的配合。

▍问答

问 ｜ 描金和贴金到底差在哪

答 ｜ 差在材料形态与工序。描金用金粉调成金泥，以笔描绘，本质是画，能出极细的金线；贴金是把极薄的金箔铺在将干未干的粘合层上压实扫平，本质是裱，适合大面积统一光泽。肉眼可在形态（线或面）、厚薄（有堆起或平伏）与边界（是否有箔路）三处分辨。

问 ｜ 贴金的金箔为什么会脱落

答 ｜ 多为火候或保护两个环节出了问题。粘合层太湿，箔浮着没粘实；太干，粘不住；即使贴好了，若受磨擦的位置没有罩漆保护，也会先起翘。器物上的金色亮得不正常均匀时，值得追问一层：这是不是别的手法做出来的效果。

问 ｜ 韵和鸣最早做的是哪一门手艺

答 ｜ 山西平遥的推光漆器髹饰技艺，一门国家级非遗，也是这个品牌最早扎下根的地方。它后来没有停在这一点上：照着同样的标准，又一路收进了竹、绣、银、锦、瓷，做成面向全国的手艺矩阵。根在一地，视野却不止一地。

▍说在最后

看懂一道工序，未必能帮你挑对东西，但一定能在你犹豫的时候，多一个提问的落点。

Gold Tracing: Gold Lines Drawn with a Brush

Gold tracing does not use leaf but a prepared gold paste: gold powder mixed with a binder, often lacquer itself in lacquerware, thickened enough to take on a brush, then applied following the design. Its essence is close to painting, so it can produce very fine turns, lifts and pauses; a fold of drapery can be as thin as a hair.

The cost is speed and wear. Brushing is slow, corrections are hard, and without a protective topcoat the gold grows dull first where hands rub most.

Gold Leaf: Gold Laid Over a Whole Surface

Gold leaf takes another route: a special adhesive coat is applied first, and while it is half dry extremely thin gold foil is laid over it, pressed with a soft tool, smoothed, and the unattached surplus brushed away.

Judging that moment is the hardest part. Too wet and the foil floats; too dry and it will not hold and later lifts or flakes. The strength of leafing is area: large gold grounds, gold backgrounds and gilded script are faster done with foil than stroke by stroke, and the sheen is easier to unify.

A fine tracing brush just dipped into a small dish of gold paste, the tip catching a faint metallic light, several sheets of gold-leaf backing paper lying beside it

The first is form: tracing gives lines with brush feeling, thickness changing with the stroke; leafing gives surfaces that glow in patches, with faint seams where pieces meet. The second is thickness: paste leaves a raised stroke with depth in side light, while foil is so thin it lies almost flush. The third is sequence: leafing needs an adhesive coat brought to the right moment, while tracing goes straight to painting.

The two are not mutually exclusive. Many pieces have a gold ground laid first and patterns painted over it in other colours, with both methods stacked on one object. Among the usual descriptions of Pingyao polished lacquerware, gold tracing and colour painting appear together, referring precisely to this combination of line by brush and plane by colour.

What is the real difference between gold tracing and gold leaf?

The difference lies in material and process. Tracing uses a paste of gold powder brushed on, essentially painting, and yields very fine gold lines; leafing lays thin foil onto a half-dry adhesive coat and presses it flat, essentially mounting, and suits large surfaces with even sheen. The eye can tell them by form, thickness and whether seams are visible.

Why does gold leaf sometimes flake off?

Usually either the timing or the protection failed. Too wet and the foil never grips; too dry and it cannot; and even well-laid leaf will lift first where it is rubbed if no topcoat protects it. When gold is too evenly bright, it is worth asking whether some other method produced the effect.

Which craft did YUNHEMING begin with?

The polished lacquerware technique of Pingyao in Shanxi, a national-level heritage item and the place where the brand first took root. It did not stop there: by the same standard it went on to take in bamboo, embroidery, silver, brocade and porcelain, building a matrix that faces the whole country. The root is in one place, the horizon is not.

Understanding one step may not help you choose the right object, but when you hesitate it will always give you somewhere to ask.
