Slumped glass is a type of patterned or textured glass formed by heating a sheet of flat glass in a kiln until it softens and gradually "slumps" into a mould beneath it. This process allows the glass to take on a wide range of custom textures, patterns, and curves.

Here’s how Slumped Glass works
The glass is custom-cut to size and cleaned to ensure the surface is free of any specks before the slumping process.
We prepare our moulds and designs. Every pattern is individually made using artisan techniques.
As the glass softens, gravity causes it to slump into the mould, capturing intricate patterns or shapes. The glass is then slowly cooled to lock in the new shape and texture.
Final touches like colour coating, cleaning, polishing ect before we deliver final product to you.
What Makes Slumped Glass Unique?
Toughened
for strength and safety — 4–5× stronger than annealed glass. Toughening is done in Christchurch, meaning your glass takes a scenic South Island “road trip” before final delivery (if toughened)
Handcrafted
No two pieces are ever the same, our team individually make every pattern from scratch. Making every piece more unique.
Customisable
Logos, text, and imagery can be incorporated to any of our slumped glass projects. The only limit is your imagination.
Colour Options
Our glass can be slumped green, grey, clear or low iron tint. It can then be colour-coated using Resene or Dulux paint with metallic highlights if you wish. The colour options are endless!
Custom Shapes and Sizes
We can create:
Curves, corners & cut-outs
Plug holes, logo etchings, shapes
Choose to have your glass colour coated to compliment your cabinetry or walls
Templates for complex installations (e.g., rangehood splashbacks)

Toughened Glass
Toughened (tempered) glass is a safety glass strengthened through thermal or chemical treatments. This process creates internal stresses—compressing the surface and stretching the interior—so when broken, it shatters into small, blunt fragments instead of sharp shards.
Due to its safety and strength, it’s widely used in windows, shower doors, splashbacks, tables, and other high-impact areas. All cutting or drilling must be completed before toughening, as post-processing will damage the glass.
When slumped and toughened, the glass meets NZ/Australian safety standard AS/NZS 2208, gaining 4–5 times the tensile strength of annealed glass while maintaining the same acoustic and weathering properties. It must be installed with setting blocks and spacers to ensure compliance and safety.
Note: Toughening doesn’t improve resistance to scratches or abrasion.
