Are you ready to start mixing your own glazes?

Do you want to increase your understanding of how glazes work?  Have a little more control over your results?  Maybe you’ve been using commercial (pre-mixed) glazes for a while now and they aren’t exactly doing what you want them to.

Perhaps you’ve reached the point in your ceramics journey that you want to start understanding the materials you’re working with and what is actually happening when you put your pottery into the kiln.

Or, it could be that the cost of commercial glaze is adding up and you would like to explore a much cheaper option.

What’s the solution to these problems?  Make your own glazes.

I’m here to tell you the basic benefits of mixing your own glazes and a list of materials to get you started.

The benefits:


Control and understanding

When you mix your own glazes, you get to know your materials so that you can adjust your recipes in order to achieve the results you are after.

Is your glaze too glossy?  Not the right shade of blue?  Knowing your materials and how they interact with each other gives you the freedom to make adjustments and fine tune your glazes to be exactly how you want them.


At my local pottery supplier, a pint of pre-mixed glaze averages $15-$20.  A pint is the common size that glazes come in around here.  The only gallon-size of commercial glaze that they carry is a clear glaze for $100, and I’d still have to mix my own colourants in.  For all the metric folks like me, a gallon is the equivalent of 3.8L.


You can make a gallon of glaze from scratch for under $5.  Seriously.


The shopping list:

I’ve put together a list of the most common glaze materials and equipment necessary to start mixing your own glazes.  With this list you will have all the ingredients you need to make a very large variety of glaze recipes.  You don’t need all of these ingredients to make one glaze, you could get by with even less, but this list will give you the widest variety of possible glazes with the smallest number of materials. I work at cone 6 and my material choices are based on common cone 6 recipes.

Base ingredients

  • Silica – 5 kg – $9
  • EPK – 5 kg – $9
  • Frit 3124 – 2.5 kg – $15
  • Gerstley Borate – 2.5 kg – $11
  • Nepheline Syenite – 5 kg – $8
  • Custer Feldspar – 5 kg – $10
  • Whiting – 5 kg – $7
  • Talc – 2.5 kg – $5
  • Dolomite – 5 kg – $8


  • Bentonite – 2.5 kg – $6


  • Copper Carbonate – 125g – $6
  • Red Iron Oxide – 500g – $6

Total: $100


For $100 you’re off to a great start

With these materials, you can make buckets and buckets of glazes of different colours and textures.  Feel free to add any other ingredients you find in your favourite recipes.

Prices will vary depending on your location.  I’m located in Canada so costs are in Canadian dollars and based on my local supplier’s prices in 2016.  Your prices will likely be even cheaper, depending on your location.
