From Clay to Light: 10 Steps to Craft Durable Porcelain Lighting at Strong Lighting

At Strong Lighting, a trusted OEM/ODM lighting manufacturer since 2015, we’ve delivered 100+ containers of porcelain lamps annually to clients like oversea brand wholesalers, DIY chain stores,and boutique hotels worldwide. Here’s a behind-the-scenes look at how raw clay becomes exquisite lighting fixtures.

Step 1: Clay Selection

We source premium kaolin clay from Guangdong mines. After 5 rounds of washing and filtering, the clay becomes as smooth as silk – perfect for creating translucent lampshades that diffuse light evenly.

Step 2: Smart Mixing

Our designers blend clay with quartz and feldspar:

20% quartz for pendant lights needing soft glow

15% feldspar for table lamp bases requiring strength

Custom ratios for outdoor fixtures facing harsh weather

Step 3: Shaping Magic

Skilled artisans shape clay using:

Hand-throwing (2 minutes per lampshade)

3D-printed molds for complex designs like floral chandeliers

Press machines for consistent batch production

Step 4: Precision Trimming

Each piece is rotated on custom wheels for millimeter-perfect smoothing. This step ensures wall thickness stays within 0.3mm tolerance – crucial for even lighting distribution.

Step 5: Artistic Touches

Choose from:

Hand-painted patterns by master painters

Laser-etched geometric designs (0.2mm precision)

24K gold accents for luxury hotel collections

Step 6: Controlled Drying

Lamps dry for 72 hours in humidity-controlled rooms. Our smart system prevents warping, even for large 60cm diameter ceiling light covers.

Step 7: Kiln Transformation

In eco-friendly gas kilns, pieces fire at 1280°C for 24 hours. This vitrification process makes porcelain:

Scratch-resistant – survives accidental bumps

Heat-tolerant – handles 100W bulbs safely

Semi-translucent – creates warm ambient light

Step 8: Gradual Cooling

A 48-hour cooling process prevents thermal shock. Our staged approach allows beautiful crackle effects for vintage-style wall sconces.

Step 9: Quality Control

Every lamp undergoes:

✅ Light diffusion test with LED arrays

✅ Tap test to detect hidden cracks

✅ Weight test – hooks hold 10kg+

Step 10: Shockproof Packaging

We use dual-layer EPP foam and honeycomb paper to protect fragile details. Our packaging withstands 1.5m drops – proven in shipping to US/European warehouses.
