The recipes offered in this course are just a starting point!
You can then explore the infinite possibilities thanks to a free online tool: GLAZY.
Glazy is a recipe exchange site and calculation software.
You can find recipe ideas there and adapt recipes to your products quickly and efficiently, so you don’t have to do mathematical calculations by hand.
But to take advantage of this wonderful tool, it is better to understand the rules of the game!
With the online course, we offer you a complementary lesson to teach you how to use this software.
An online course carefully crafted

Potter – Ceramist for over 40 years
“I have been teaching glazing for more than 10 years in my training centre, the Creamik school. But I found that my course materials (texts, books, graphics) were not effective enough, and the scope of my courses was too limited.
That’s why I created this online video course, accompanied by summary PDFs , comprehension questions, and all my recipes.
It took a year of preparation to create these videos using a pedagogical approach that far exceeds what can be done in a book and that has even more benefits than an in-person course.
The proof: my students who are doing professional training are required to watch them.
Nothing like it exists in ceramics!“

Anne Laure Servit
“Matthieu’s online courses are a gold mine for anyone who wants to start creating glazes or, like me, get a refresher (3 years after my professional training).
The courses are clear and concise: it’s a joy to see Matthieu right in my studio.
Glazing – what a pleasure but what a science! The courses are essential.
Matthieu also discusses other topics and gives great tips and advice.
I just opened my first two kilns.
A thousand thanks, Matthieu, and bravo.“
” The instruction offered is of exceptional quality. The course, which is specific and concrete, is extremely well presented in an effective way: a sentence, a piece of information. The illustrations accompany the presentation perfectly.

Frequently Asked Questions
What does “lifetime access” mean?
This means that the course you buy is yours: you can log in to the member area of the website and watch the videos as often and for as long as you want, without ever having to pay any additional fees.
(We also strongly recommend that you watch the videos several times to fully immerse yourself in the content!)
Any additions or improvements to the course in the future are also included in your purchase: you will have access to them without having to pay anything more.
Do I need to have basic knowledge to take this course?
No. No prior knowledge is required to take this course.
What is the point of buying the basics course and the advanced course at the same time when you are a beginner?
The basics course will teach you how to mix glaze powders and how to fire your glazed ceramics.
The advanced course covers, among other things, the influence of clay on glaze, the different types of kilns and the choices you have when buying one. It demonstrates all the techniques for applying glaze to pottery: with a brush, dipping, or using a spray gun. These are important things to consider when purchasing your clay and equipment and are very helpful to know when you are starting out.
The parts of the advanced course that deal with the layering of glazes and crystallization also open up interesting perspectives for you from the start.
Math is not my forte: is this course for me?
You don’t need any prior knowledge of math or chemistry. We offer video reminders that cover everything from A to Z: what is a fraction, a percentage, a cross product in math, a chemical formula, orders of magnitude and even molecular weights in chemistry.
You just have to be willing to learn and let go of that old image of yourself or your high school math classes. The lack of a concrete goal is often the reason someone becomes allergic to math, and today, you have a very good reason to learn it.
You should also know that though we consider it very important to do your first calculations of glazes by hand, so that you understand in depth the steps of creating a recipe, you will not have to calculate each of your glazes for the rest of your life: there is good software for this, and we will show you how to use it.
Why can’t defects be avoided even with pre-made glaze?
These glazes are designed by manufacturers to avoid defects. If all goes well, there shouldn’t be any.
But the manufacturer tested their glaze on a specific clay, and the clay has a huge influence on the glaze (as does the kiln, the laying of the glaze, and many other parameters). The manufacturer cannot foresee the variations of all these factors.
If your ceramics come out of the kiln with defects, you can try these adjustments:
=> If the glaze has pimples, you have fired at too low a temperature; fire the next kiln a few degrees higher.
=> If the glaze became runny, you fired too high; fire lower next time.
=> But what if you still have one or the other? What if the clay has influenced the colour, and you’re not getting the hue you were hoping for?
In this case, you will not be able to do anything, because you do not know the composition of the glaze. You will not be able to modify it to solve the problem.
Hence the convenience of making your own glazes: you will be able to control all your parameters and will always be able to rectify the situation when a defect appears.
Is it really possible to create your own glazes after only taking this online course?
Yes! Including (more complex) crystallization glazes, if these interest you. Many students have already demonstrated that it is possible!
Of course, like any new skill we learn, it requires commitment, some rigour and training. There will be failures, moments of discouragement and eureka moments. The same goes for wheel-throwing!
What equipment do I need (and how much will it cost)?
To do what is explained in the course, you need at least:
– A precision scale for 100g (10€)
– A precision scale for 10kg (80€)
– Small equipment (whisk, sieve, ladle, cups, basins, brushes, etc. ) (140€)
You can therefore get equipped for around 230 euros. (Prices in France. Prices in different countries may vary.)
Do you talk about the hazards of the products?
Yes! We describe each product, with its qualities and its downsides, including the hazards of handling them and the use of glazes when you make dishes that will hold food.
Overall, when it comes to dishes that will be used for food, the main danger is a matter of proportion between the products (the glaze must be impervious to weak acids, such as lemon juice or vinegar in a salad dressing).
In short, at least 3 moles of silica are needed for 0.3 moles of alumina in a formula, so that the glaze can be used for dishes. Don’t worry if you don’t understand this answer; everything is explained in the course…
Do I need a kiln to take this course?
No: to begin with, you can find a ceramist or a ceramics centre that will rent their kiln; this is quite common.
Suggest that they fire a sample of your clay and your glazes first to give them confidence: low-temperature clay or glaze in a high-temperature kiln can cause significant damage to the kiln. If the potter tries a sample first, they can make sure you have not made a mistake in temperature, without taking any risks for their kiln.
Watching the course before buying a kiln will also allow you to be sure you make the right choice when you purchase one, since an entire video of the course is dedicated to describing the types of kilns, including their advantages and disadvantages.
Why is your online course focused on high-temperature glazes?
High-temperature glazes are much easier to make: the lower the melting point of a glaze, the more complex the mixture of products.
It is not impossible to make your own low-temperature glazes, but you usually have to use “frits,” products prepared by manufacturers, which are relatively expensive. As one of the great advantages of making glazes is reducing your costs, using frits loses some of its appeal.
One might choose to make low-temperature glazes because a low-temperature kiln is less expensive to buy. In the long term, this is not a good reason, because low-temperature glazes are much more expensive!
