Silver sheet wire and tube in jewellery making
Understand silver sheet, wire and tube, their dimensions and temper, and how those starting forms differ from a finished design.
In this article
Silver can reach a jewellery bench as sheet, wire or tube. These words describe its starting shape. Supplier catalogues list fine and sterling silver in several such forms, with dimensions provided for each. A stock-form name is useful workshop vocabulary; it is not a description of a finished piece’s quality. Supplier form catalogue.
Sheet gives the maker a flat starting surface
Sheet is specified by length, width and thickness. Wire has a length and a cross-section, the shape seen at its cut end. That profile can be round, square, rectangular, oval or D-shaped. Naming the profile helps distinguish materials that a photograph of a coil might make look similar. Sheet and wire listings.
Imagine two workshop labels: “sterling sheet, 40 mm by 30 mm by 0.8 mm” and “sterling round wire, 1 mm diameter.” These invented labels describe different starting shapes. They say nothing about the final design. For a commission, let the maker identify which measurements concern the starting material and which describe the finished jewellery.
Tube has an inside as well as an outside
Tube has a hollow centre. Round tube needs an outside diameter, an inside diameter and a wall thickness. One supplier example lists 3.5 mm outside, 2.6 mm inside and a 0.45 mm wall. The wall lies on both sides of the opening, which explains the 0.9 mm difference between the diameters. Tube dimensions.
A maker can adapt tube into a stone setting. In Kernowcraft’s demonstrated project, the inside is prepared to support the stone and the upper rim holds it. The actual stone’s dimensions guide the choice of tube. A tube diameter on a supply list is therefore not a universal stone-fitting rule. Tutor’s tube-setting example.
Hardness condition is a separate detail
Stock may be supplied annealed, meaning softened for shaping, or in a harder condition. Cooksongold’s technical catalogue distinguishes soft annealed wire from hard wire. Form, thickness and temper belong in different parts of a specification; “wire” by itself leaves those choices open. Supplier temper information.
When discussing a piece, ask the maker to describe the intended construction in everyday terms. A useful answer identifies the starting form and then explains the resulting design. Avoid treating a single stock measurement as a shortcut for comfort, strength or craftsmanship.
Continue with fine silver and sterling silver to separate composition from component function. For the volume of a finished design, hollow jewellery forms explains why the appearance and the amount of metal need separate discussion.
