Caring for Polystone Busts: A Practical Display Checklist
Everything below is written for display-focused collectors who are weighing Caring for Polystone Busts: A Practical Display Checklist — the numbers, the trade-offs and the details that decide whether the piece still looks right three years in.
Light Damage Is Cumulative
UV breaks polymer chains in paint binders and clear coats; the damage shows first as lost gloss, then as yellowing, and it is irreversible. This is why a piece can look perfect for two years and dull by year four without anything ever touching it — the light was doing the work the whole time.
Warm White LED Wins
Halogen is the worst common choice: it dumps both UV and convective heat onto the piece. Warm white LED at 2700–3000 K with under 0.1% UV and a colour rendering index of 90 or higher is the practical answer, provided the fixture genuinely filters UV and infrared rather than merely claiming to on the box.
Polystone Care in Three Rules
Support the base, never lift by the head or an arm, and never reach for a solvent when a stain appears. Polystone is brittle under point impact and slightly porous, so handling and cleaning decide how a piece looks in five years far more than the initial paint job does.
Separate Scales and Rooms
If you own quarter and sixth scale, display them apart so each reads correctly. Mixed scale at one eye level is the most common first-year mistake, and it flattens both lines so neither looks like the size it actually is.
Source Comparison
| Source | UV | Heat | Verdict |
|---|---|---|---|
| Direct sun | High | +10 °C | Avoid |
| Halogen 50 W | Yes | +10–15 °C | Avoid |
| Warm LED 2700 K | <0.1% | Very low | Best |
The short version: material and edition size set the ceiling, finish sets the day-to-day impression, and display decides how much of that you actually see.
