Free Guide

Do you have these glaze challenges?

  • You don't know how much water to add to your glazes
  • You get different results every firing
  • Your glazes aren't turning out as expected
  • You can't seem to keep your glaze thickness consistent

Grab my FREE GUIDE

You'll start understanding your glaze results better when you measure specific gravity. It just takes a few simple steps to calculate the water content of your glazes and then it's easy to keep them consistent. No more guessing!

Consistent water content = consistent application thickness = consistent results.

I find ceramic glazes to be absolutely fascinating. I had no idea when I started working with clay that glazes would become the main focus of my life. Glazing was always an afterthought and I basically ruined most of my pieces by glazing them…

Why I Use a Graduated Cylinder for Measuring Specific Gravity

Why I Use a Graduated Cylinder for Measuring Specific Gravity

I use a graduated cylinder for measuring specific gravity. A slender container is going to have smaller increments than a wide container, giving higher accuracy. You could compare this concept to using a scale with 1g increments vs 5g increments. The smaller measurement is…

Why I Don’t Use a Hydrometer to Measure Specific Gravity

Why I Don’t Use a Hydrometer to Measure Specific Gravity

I didn’t always know about measuring specific gravity. Of the 10 years that I’ve been mixing glazes, I’ve only been measuring specific gravity for 3 of them. It wasn’t a technique I learned in school. But… I had heard about it enough times that eventually I used it to try…

How to Fix a Hard-Panned Glaze with Epsom Salts

Have you ever had a glaze settle into a rock hard layer on the bottom of your glaze bucket? It’s impossible to mix and even if you do get it mixed, it just settles out again. This annoying phenomenon is called “hard-panning” and it often happens to glazes that don’t have enough…

Why Specific Gravity Isn’t Listed on Glaze Recipes

Why Specific Gravity Isn’t Listed on Glaze Recipes

If you’ve been glazing for any length of time, you may have heard about the importance of measuring the specific gravity of your glazes and you may have found yourself wondering: “If it’s so important to measure specific gravity, why aren’t specific gravity values published on glaze recipes?”

How the Water in Your Glaze is Affecting Your Results

How the Water in Your Glaze is Affecting Your Results

Does any of this sound familiar? You unload a piece from the kiln and the glaze turned out perfectly! So you glaze more pieces with the same glaze combination, fire them, and they turn out completely different… OR… You mix a small test batch of a glaze and LOVE how it looks…

How to Make a Cone Pack

How to Make a Cone Pack

In this post, you’ll learn how to make a cone pack using pyrometric witness cones set into a coil of clay. Cones are important for measuring the heatwork of your firings.

Temperature vs Heatwork – Why We Use Witness Cones

Temperature vs Heatwork – Why We Use Witness Cones

I receive a lot of glaze questions and the first question I generally ask in return is “What did the cones look like?” Knowing whether the kiln was over- or under-fired is important for diagnosing many glaze issues. Sometimes I’m told a kiln temperature in response. But…

How to Calibrate Your Kiln Sitter for Accurate Firings

How to Calibrate Your Kiln Sitter for Accurate Firings

If you’re anything like me, then your first kiln wasn’t or isn’t going to be the digital programmable kind. Many of us start out with a manual kiln that we got second hand. I have 4 different sized kilns in my home studio and none of them are digital or programmable.
