Glass Quality
Every glass shade we offer is handcrafted and carefully checked by Mullan before it reaches you. Because each piece is made by hand, subtle variations and small surface marks can naturally occur. These details are part of the making process and are considered within the expected character of handmade glass.
The table below outlines the types of features you might see in artisanal glass and clarifies which are considered acceptable and which are not.
Please note that minor variations are a natural part of handmade glass and are acceptable within the following limits:
| Feature | Acceptable Standard |
|---|---|
| Air bubbles | Less than 4mm in diameter, with no more than four per 10 cm² area |
| Symmetry / oval shape | Acceptable if overall balance of the fixture is maintained |
| Neck level | Acceptable if the glass angle is less than 5° |
| Chips on edges | Up to 2mm depth; deeper around the neck only |
| Scratches / cracks | Acceptable if they don’t compromise strength and aren’t visible from 1 metre |
| Smudges / trails | Acceptable if not noticeable from 1 metre |
| Wall thickness | Variation less than 4mm |
