Prototypes and Samples in Custom Metalwork: What to Expect and How Long It Takes

By Bhavini Khullar | Founder, Byaas | Adjunct Professor, Montclair State University

Short answer: Expect a rough prototype, a finish sample and a pre-production sample, with one or two revision rounds. At Byaas a first custom sample takes about 4 to 6 weeks.

You cannot feel a render. You cannot lift a PDF and notice that it is a little too light for its height, or run your thumb along an edge and find it slightly sharp. Metal is judged by the hand before the eye, and the first time anyone truly meets your product is when they hold the sample.

That moment matters more than ever. Your end customer is buying fewer things and expecting each one to be right. In metalwork, so much of what makes a piece right is physical: weight, balance, temperature, the softness of a burnished surface. The sample is where you check all of it. Here is what to expect.

The different kinds of samples

• Render or proof sketch: a visual check of shape and proportion.

• Rough prototype: a first physical version to test form and fit.

• Finish sample: a piece showing the exact color and surface.

• Pre-production sample: a near-final piece made the way production will be made.

Ask which of these your manufacturer plans to make, and what each costs.

What to check on a first prototype

Proportion first: does it look right at full size, on a real table? Then function: does the taper seat firmly, does the vase hold water, does the hook carry its load? Then stability and weight. Finally, feel: edges, welds, the underside. Photograph it in daylight and under warm indoor light, because brass changes character with lighting.

What to check on a finish sample

Look at tone, sheen and consistency against your reference, in the same light. Check curves and flats, because a finish can read differently on each. Ask how it will age and whether it is lacquered. To see how much finish changes a form, compare the burnished and polished Balancing Act holders. Our guides to brass finishes and lacquered vs unlacquered brass help.

A tip from our own range: choose a finish that will still feel right after many seasons of restyling. Try the sample with a few of this year's colors, such as the ice blue, burgundy and amber Emily Henderson's team expects to define 2026 (Emily Henderson). A warm burnished holder works with all of them. A finish chosen to match one trend color will date with it.

How to give useful feedback

Be specific: "increase base diameter by 5 mm" is far clearer than "make it more stable." Mark photographs with arrows. Separate must-fix items from nice-to-haves. Reply in one batch rather than a stream of small messages, so the record stays clear.

Common sample problems

The finish looks different from the reference because of lighting. A candle cup is a touch tight or loose. The base feels light for the height. A weld line shows after polishing. Each is easy to fix at sample stage and expensive later, which is exactly why samples exist. In a family workshop like ours, you can often discuss these points directly with the people making the piece. Read more about our workshop.

The pre-production sample

This is your approval piece. It should match what production will deliver. Sign off in writing and keep it as the reference. If a later batch differs, you have a clear basis for the conversation.

How many revisions are normal

One or two rounds are common. Simple designs may pass first time. Complex forms or new finishes may need more. Clear feedback with measurements keeps rounds to a minimum.

How long samples take

At Byaas, a first custom sample takes about 4 to 6 weeks. A simple turned or spun piece samples faster than a hand-worked repoussé panel. If you have a launch date, build in a buffer.

What samples cost

Samples take real labor and material, so most manufacturers charge for them, often crediting the cost against a later order. Ask about the sample policy at the start. See custom brass manufacturing with Byaas.

A sample approval checklist

• Size and proportion against the drawing

• Weight

• Finish in daylight and indoor light

• Base, welds and edges

• Function: candle fit, water tightness, load

• Logo placement and legibility, if branded

• Result recorded in writing with photographs

Reviewing remotely

If you are not near the workshop, a video call speeds up early rounds. Ask to see the piece from several angles, under natural light, beside a ruler. Agree changes on the call, then confirm in writing. Remote review cuts rounds, but it does not replace holding the final sample.

How samples protect both sides

A signed-off sample protects you, because you know what production will deliver, and protects the maker, because everyone knows what was agreed. Our quality control guide explains how production is checked against it.

Frequently Asked Questions

How long does a metal sample take?

At Byaas, a first custom sample takes about 4 to 6 weeks, depending on design, finish and workload.

Do manufacturers charge for samples?

Usually, because samples take material and skilled time. Some credit the cost against a later order.

Can I approve from photographs?

Photos help, but a physical sample is far safer for metal. Weight, finish and feel are hard to judge on screen.

What if production differs from the sample?

Keep the approved sample as the reference and agree tolerances in writing. A good maker corrects genuine differences.
