Because buttons have been manufactured from almost every possible material, both
natural and
synthetic, and combinations of both, the history of the material composition of buttons reflects the
timeline of materials technology. Buttons can be individually crafted by
artisans,
craftspeople or
artists from
raw materials or
found objects (for example
fossils), or a combination of both. Alternatively, they can be the product of
low-tech cottage industry or be
mass-produced in
high-tech factories. Buttons made by artists are
art objects, known to button collectors as "studio buttons" (or simply "studios", from
studio craft). In 1918, the US government made an extensive survey of the international button market, which listed buttons made of
vegetable ivory,
metal,
glass,
galalith,
silk,
linen, cotton-covered
crochet,
lead,
snap fasteners,
enamel,
rubber,
buckhorn,
wood,
horn,
bone,
leather,
paper, pressed
cardboard,
mother-of-pearl,
celluloid,
porcelain,
composition,
tin,
zinc,
xylonite,
stone, cloth-covered wooden forms, and
papier-mâché. Vegetable ivory was said to be the most popular for suits and shirts, and papier-mâché far and away the commonest sort of shoe button. Nowadays, hard plastic, seashell, metals, and
wood are the most common materials used in button-making; the others tending to be used only in premium or
antique apparel, or found in
collections. Over 60% of the world's button supply comes from
Qiaotou, Yongjia County,
China.
Decoration and coating techniques Historically, fashions in buttons have also reflected trends in
applied aesthetics and the
applied visual arts, with buttonmakers using techniques from
jewellery making,
ceramics,
sculpture,
painting,
printmaking,
metalworking,
weaving and others. The following are just a few of the construction and decoration techniques that have been used in button-making:
Styles of attachment •
Flat or sew-through buttons have holes through which thread is sewn to attach the button. Flat buttons may be attached by
sewing machine rather than by hand and may be used with heavy fabrics by working a thread shank to extend the height of the button above the fabric. •
Shank buttons have a hollow protrusion on the back through which thread is sewn to attach the button. Button shanks may be made from a separate piece of the same or a different substance as the button itself, and added to the back of the button, or be carved or moulded directly onto the back of the button, in which latter case the button is referred to by collectors as having a 'self-shank'. •
Stud buttons (also push-through buttons or just studs) are composed from an actual button, connected to a second, button-like element by a narrow metal or plastic bar. Pushed through two opposing holes within what is meant to be kept together, the actual button and its counterpart press it together, keeping it joined. Popular examples of such buttons are shirt studs and
cufflinks. •
Snap fasteners (also pressure buttons or press studs) are metal (usually brass) round discs pinched through the fabric. They are often found on clothing, in particular on denim pieces such as pants and jackets. They are more securely fastened to the material. As they rely on a metal rivet attached securely to the fabric, pressure buttons are difficult to remove without compromising the fabric's integrity. They are made of two couples: the male stud couple and the female stud couple. Each couple has one front (or top) and rear (or bottom) side (the fabric goes in the middle). •
Toggles are stick-like, with a cord attached at the center. They are passed endways through a hole and then rotated sideways. •
Magnetic buttons, as the name implies, are buttons that attach to each other by being magnetic. The buttons can be attached either by sewing or snapping them into the fabric.
Fabric buttons •
Covered buttons are fabric-covered forms with a separate back piece that secures the fabric over the knob. •
Mandarin buttons or
frogs are knobs made of intricately knotted strings. Mandarin buttons are a key element in
Mandarin dress (
Qi Pao and
cheongsam in
Chinese), where they are closed with loops. Pairs of mandarin buttons worn as
cuff links are called
silk knots. •
Worked or cloth buttons are created by
embroidering or
crocheting tight stitches (usually with
linen thread) over a knob or ring called a
form.
Dorset buttons, handmade from the 17th century to 1750, and Death head buttons are of this type.
Button sizes The size of the button depends on its use. Shirt buttons are generally small, and spaced close together, whereas coat buttons are larger and spaced further apart. Buttons are commonly measured in
lignes (also called
lines and abbreviated
L), with 40 lines equal to 1 inch. For example, some standard sizes of buttons are 16 lignes (10.16 mm, standard buttons of men's
shirts) and 32 lignes (20.32 mm, typical button on
suit jackets). ==In museums and galleries==
