Mirror Finish

Definition and Overview

Mirror finish is a finish that suppresses surface irregularities and reflects light relatively evenly, giving a bright, glossy appearance. It does not indicate the button’s material, number of holes, or whether it has a shank, but mainly describes the surface appearance.

The degree of gloss and the clarity of reflections vary depending on the material, surface condition at molding, polishing method, and whether it is painted or plated. Even with the same mirror finish, the appearance may differ depending on the color or lot.

Materials and Structure

Mirror finish is used for resin buttons such as polyester resin buttons, metal buttons, and shell buttons. However, whether the finish is possible and its durability differ by material, so it is important not to judge the material or performance from the mirror finish description alone.

In addition to two-hole, four-hole, and cat-eye surface-hole buttons, mirror finish can also be applied to shank buttons with shank loops or tunnel shanks. Holes and shanks relate to the attachment structure, while mirror finish relates to the surface treatment, so they should be checked separately.

• For surface-hole buttons, check whether there is gloss all the way to the edge of the holes.
• For shank buttons, check not only the surface but also the material and strength of the shank.
• For a metal-like appearance, distinguish between solid metal, plating, and painted specifications.

Size Notation and Applications

Button size is generally expressed by diameter in mm or lignes. Lignes are a customary unit for buttons, and in orders and specifications, it is easier to verify if diameter in mm, thickness, shank height, and hole size are also listed as needed, rather than using only lignes.

Mirror-finish buttons are used for shirts, blouses, cardigans, jackets, coats, dresses, and formal wear. Select the gloss and size while considering the luster of the fabric and harmony with metal findings and accessories.

Attaching Method and Handling Precautions

For surface-hole buttons, thread is passed through the holes to attach the button, and if thickness or extra room at the front opening is needed, a neck wrap is used. For shank buttons, thread is passed through the shank hole. If the sewing thread is pulled too tightly, resin, shell, or glass buttons may crack or chip.

Resistance to washing, dry cleaning, and ironing is determined by the material and surface treatment specifications, not by the mirror finish itself. Check the care label and the handling conditions for the accessory, and do not apply the iron directly to the button; use a pressing cloth if necessary.

Contact with or rubbing against other hard accessories may cause surface scratches, haze, or damage to the coating. For specifications containing metal, discoloration or corrosion may also occur due to moisture, sweat, or detergent residue, so confirm through product testing.

Differences from Similar Terms

Satin finish often refers to a smooth appearance with subdued gloss, and the reflection appears softer than in mirror finish. Sandwashed finish has a matte appearance created by fine irregularities, and its surface appearance is the opposite of mirror finish.

Gloss is used as an expression indicating the degree of shine, whereas mirror finish specifically refers to a finish intended for smoothness and reflectivity. Confirm the gloss, color, and visibility of scratches with the actual item or sample, and share the desired appearance.
