Louis Comfort Tiffany directed an influential studio, but designers, glass selectors, cutters, solderers and workshop staff all contributed to finished lamps.
Start with the problem, not the product photograph
Resemblance to a known motif is not historical provenance. For Louis Comfort Tiffany and the Tiffany Studios team, use dated sources and state uncertainty plainly.
Photograph the proposed position straight on and from the side. Record the full dimensions, lampholder, bulb, connection method and the main task. A close product image rarely shows room scale, door movement or the angle from which a bare bulb becomes visible.
Three distinct decisions
1. Decide the job before the style
Separate creative direction, design attribution, manufacture and modern retail branding instead of collapsing them into one person.
Keep this evidence: write the main task and the one constraint that could rule the fitting out.
2. Measure the real fitting envelope
Create a source table with date, named role and evidence for every attribution.
Keep this evidence: record every dimension from one named reference point and photograph the tape measure in place.
3. Test the result from normal positions
Check whether later scholarship or museum cataloguing has revised an older simplified account.
Keep this evidence: repeat the check by day and after dark, using the bulb and furniture layout you expect to keep.
Compare two models without being misled by the image
| Evidence | Why it matters | Practical check |
|---|---|---|
| Complete dimensions and weight | Glass, base, chain and canopy may sit outside the highlighted shade dimension. | Dimensioned sketch, total weight and a 1:1 mock-up |
| Connection and bulb | Voltage, plug or fixed connection, bulb count, cap, lumens, shape and maximum wattage affect suitability. | Rating label, current product page and trial with the intended compatible LED |
| Switched off and on | Dense stained glass can glow strongly at night yet read much darker in daylight. | Compare from the same angle in the actual room |
A real TiffanyLight.co.nz product as the worked case
30 cm Baroque-style stained-glass pendant
A compact 30 cm pendant used to test table margins, hanging height and the difference between shade diameter and total suspended size.
This model demonstrates the method; it is not an automatic recommendation. Draw its complete dimensions, verify the current electrical specification and test the proposed light in the real room. Product details can change, so check the live page before buying.
Confirm on the product page: total dimensions, weight, voltage and connection, lampholder, maximum wattage, included parts and installation conditions.
Practical New Zealand home scenario
Use the motif on 30 cm Baroque-style stained-glass pendant as a visual comparison, never as an attribution. Build a short timeline from museum or archival objects and distinguish designer, historical workshop, modern maker and retailer. Without provenance, describe the current product accurately as Tiffany style.
Common mistakes
- Treating motif resemblance as proof of maker.
- Using an undated retail description as the only historical source.
- Describing a studio production as one person’s manual work.
Final checklist
- Sources include institution, author and date.
- Modern product and historical object are distinct.
- Design and manufacture are separated.
- Provenance does not rely on motif alone.
- Uncertainties are recorded.
Record sheet: model, complete dimensions, total weight, voltage and connection, lampholder, chosen LED, position, mock-up photograph and check date. The current product information and maker’s instructions take priority over general guidance.
