V&A T.184-1948, Embroidery on gauze-banded plain weave silk robe, China (late 17th century-18th century)

== Artifact Information ==
The robe is made of gauze-banded plain weave silk with embroidery. This robe is a woman's garment that may be the earliest non-ecclesiastical Chinese garment in the Museum. The grand is a rich red silk that has horizontal bands of fruiting pomegranates (symbolizing a woman with many kids) in gauze weave running across the fabric at widely spaced intervals. Over this, there is shiny embroidered decoration of fruits, flowers, birds and mythical beasts [1].
Victoria and Albert Museum, London, UK T.184-1948
== Summary of results ==
center|frame|Analytical results by Jing Han [2]
Traditionally used Chinese dyes, pagoda tree buds, turmeric and safflower had been identified as the dyeing sources of this Chinese woman's robe [2]. Berberine was found in sample 2, a green thread from the pattern. Quite a few plants can generate berberine as a yellow dye [3]. The most widely used were Phellodenrom spices, for exampleAmer cork tree and Chuan Huang Bo (Huangbo from Sichuan).

V&A T.187-1948, Woman's robe of weft-pattern woven silk, China (early 18th century)

== Artifact Information ==
A women's woven silk with supplementary weft patterning robe (with design of sky, earth and water, 9 large five-clawed dragons pursuing and clasping the sacred discs among clouds in green, blue, red, yellow and brown silks and gold thread, Lined with pink figured silk) is unlike the other Chinese women's garments in the Museum, but the curators and conservators of V&A museum knew from 18th-century pictorial sources that it was very fashionable at the time. It is front-fastening, whereas many other robes fasten to one side. Its decoration was undertaken on the loom as weaving techniques advanced, rather than being added later in the form of embroidery. The particular layout of the dragon motifs also marks it out from other garments in the V&A's collection [1].

V&A T.43-1952, Embroidered robe, China (1770-1820)

== Artifact Information ==
This embroidered robe may have been made from embroidered lengths originally intended to be tailored into a dress for a female member of the royal family. It was found that the robe might have been assembled at a much later date than when the dress lengths were made because the construction of the robe does not follow standard design and that the trims used on different parts of the robe suggest a latter-day intervention [1].

V&A T.753-1950, Emperor's court robe, China (1875-1908)

== Artifact Information ==
This is a full length court robe with a fully gathered skirt which is right-side fastening with gilt buttons. It has long and tight sleeves with horse-hoof cuffs. It has a yellow silk plain weave lining throughout [1].
By close examination, it was that that the robe has a yellow twill (2/1) ground embroidered with floss silks and gilt threads in satin stitch and couched work. The robe is identified as one made for the emperor because the robe bears the "twelve symbols", a design that was reserved for exclusive usage for an emperor's court clothes. The "twelve symbols" are: the Sun and Moon discs are on shoulders, the three star Constellation and the Mountain are at neck level, the Axe Head, the Fusymbol (resembling two Es back to back), the Pheasant and the Dragon are on the upper part of the garment, the pair of Sacrificial Cups, the Flames, the Waterweed and the Grains are on the skirt band.

Traditionally used Chinese dyes, pagoda tree buds and turmerichad been identified as the dyeing sources of this Chinese court robe [2]. The result is consistent with previous studies. Identification of a synthetic dye is also mentioned. The result agreed with the date of the robe, a late 19th century to early 20th century date. That was when synthetic dyes was imported and been used by dyers in China.

V&A T.9-1923, Embroidered child's robe, China (19th century)

== Artifact Information ==
The robe is a child's robe made of red silk satin, embroidered with colored silks and gold thread. There are eight celestial dragons with four-clawed on the robe. The dragons are chasing flaming pearls, amid which bats (fu, homonyms for happiness). Below is Meru, the sacred mountain of the Buddhists, rising from the waves. Lined with pale blue silk damask (floral pattern). It was found that a piece of red satin has been glued to one corner, where the jacket was defective and this is decorated with applied pieces of silk embroidery [1].

Valenciennes lace

== Description ==
A flat, even-texture, bobbin lace made in the French town of Valenciennes from about 1705 to 1780. Valenciennes lace was still made on a reduced scale after that time in other areas and is currently made in Ypres. Over 1000 bobbins may be used in Valenciennes lace to make both the pattern and the background from a single set of threads. From 1715, the lacemakers in Valenciennes only used a diamond shaped background. Similar style laces made earlier in the town and made in surrounding regions had square or circular background patterns. By 1830, the diamond pattern was replicated in machine-made laces.
