Gold leaf 101: what real gilding actually involves
May 2026 · 5 min read
'Gold finish' gets used loosely to describe everything from actual gold leaf to metallic paint. They are not the same thing, and the difference shows up immediately under temple lighting — which is usually the whole point of commissioning a gilded idol in the first place.
The leaf itself
Gold leaf is beaten to a thickness measured in microns — thin enough to be handled with a brush rather than fingers, since skin oil alone will tear it. It's applied in individual sheets over a prepared adhesive size, not sprayed or brushed on as a liquid.
Surface prep matters more than the gold
Most of the labour in gilding is actually before the leaf goes on: the surface has to be sanded, sealed and coated in a tacky size layer at exactly the right stage of tack — too wet and the leaf wrinkles, too dry and it won't adhere. This is where experience shows more than in the gilding step itself.
Burnishing and layering
After application, each panel is burnished by hand to seat the leaf and bring up shine, and for pieces meant to show depth rather than a flat gold surface, patina glazes are built up in layers over the leaf rather than applied as one coat.
The result — real hand-applied leaf, burnished and sealed — reflects light in a way that paint simply doesn't replicate, and it's why we treat gilding as its own finishing discipline rather than a paint colour option.
