Lesson 1Properties of genuine gold leaf: karat, microns, colour stability, and handlingStudy how karat, thickness, and alloy composition affect colour, malleability, and tarnish resistance in genuine gold leaf, and learn correct handling, storage, and cutting methods to avoid waste, damage, and surface defects.
Karat ratings and alloy metal proportionsMicron thickness and mechanical strengthColor stability and tarnish resistanceHandling loose leaf on cushion and tipStorage, transport, and contamination risksLesson 2Gold leaf thickness and nomenclature (e.g., 23k, 24k, loose leaf sizes, micron ratings)Clarify how karat labels, leaf formats, and micron ratings relate to purity, durability, and working feel. Learn to read manufacturer charts so you can match leaf type and thickness to project demands and budget constraints.

Learn when each format excels, how to adapt technique for flat or carved work, and how to minimise waste, creasing, and unintended double gilding.

Learn mixing, application, and sanding methods that create smooth, responsive grounds for water gilding.
