Glazing Like the Old Masters: What Conservation Science Actually Tells Us
If your glazes look dull, sink in, or fail over time—this is why
A live Technical Studio Session with George O’Hanlon.
Glazing is often taught as a simple technique—thin transparent layers over opaque paint.
That explanation leaves out what actually matters.
This session explains glazing as a material system: how it works, why it fails, and what decisions control the result.
Live Technical Studio Session
Thursday, May 28, 2026
10:00 AM Pacific Time
Session Format
This Technical Studio Session is structured to combine focused teaching with practical problem solving:
- 45 minutes — Core presentation
- 15 minutes — Studio Problem Clinic
- 30 minutes — Open Questions & Answers
Seats are limited to keep the session interactive.
Join live to ask questions and get direct guidance.
Replay available only to Artisan members. Technical Studio Sessions are held live each month.
Left: a thin glaze with insufficient binder and poor film formation—color appears flat, desaturated, and matte.
Right: a properly structured glaze—light passes through the layer and returns from the underpainting, producing depth, saturation, and a unified surface.
This is not a difference in pigment or technique. It is a difference in how the paint film is constructed.
This Session Includes:
- The real mechanism of how glazes create depth
- Why modern glazing methods often fail
- How solvents affect binder distribution in paint
- Practical steps you can apply immediately
Replay available to Artisan members only
Why Glazing Fails in Practice
For most artists, glazing is taught without structure.
What’s missing:
- What actually controls transparency
- How underlayers determine results
- Why solvents change paint behavior
Common results include:
- Dull or muddy color
- Sinking-in
- Weak paint films
- Loss of luminosity
These are not random defects. They are predictable outcomes of how paint is constructed.
If Your Glazes Look Right Wet—but Fail Dry—This Session Is For You
- Color loses depth and becomes flat or gray
- Dark glazes dry lighter and less saturated
- Surface gloss disappears unevenly across the painting
- Layers feel thin but still fail to adhere properly
- Repeated glazing does not increase depth—only muddies color
These are not technique problems. They come from how the paint film is constructed.
What You Will Learn
This session explains the material science and historical practice behind stable painting.
What to Change in Your Paint
Why transparency labels are not enough • How to control paint structure in glazes
How Glazing Actually Works
The optical system behind depth and saturation • Why underlayers matter more than pigment choice
Exactly What To Do in Your Studio
How to prepare a surface for glazing • How to build stable glaze layers
Studio Problem Clinic
A new feature of the Technical Studio Sessions is the Studio Problem Clinic.
Members may submit studio problems related to the session topic—such as cracking, sinking-in, or unexpected paint behavior. Selected submissions are reviewed during the session.
The goal is not only to answer questions but also to demonstrate the reasoning behind diagnosing painting problems.
This makes each session both a technical presentation and a practical problem-solving discussion.
We focus on real issues such as:
- Glazes that sink in or lose gloss
- Weak or underbound layers
- Poor adhesion between layers
This is not a generic Q&A—it is a structured diagnostic session. Because these cases come from real studios, the discussion often reveals issues that are rarely covered in books or standard instruction.
Why Attend Live
A live Technical Studio Session gives you more than a recorded lecture.
Get direct guidance on how to adjust your materials—not just theory.
You can see the material presented in sequence, hear the reasoning behind recommendations, and ask questions about your own painting methods during the Q&A.
Ask questions during the session
Follow the argument step by step
Learn from the questions other painters ask
Get direct guidance on your materials
See how glazing problems are diagnosed
Ask questions specific to your work

Technical Studio Sessions Are a Monthly Series for Serious Painters
This session is part of the Technical Studio Sessions series at Painting Best Practices.
Artisan members receive access to live monthly sessions focused on the materials, methods, and long-term behavior of oil painting.
Each session focuses on a specific structural problem and how to correct it in practice.
