Common Myths About Glaze Dipping, Chemistry & Firing Schedules I Stopped Believing

I’ve been on quite the journey with glaze dipping, chemistry, and firing schedules in my pottery practice. Over the years, I’ve encountered a myriad of myths that seemed to float around like they were gospel truth. I’m here to share the ones I’ve debunked and how the realities of glaze work have profoundly changed my approach. When I first stepped into the world of ceramics, I was overwhelmed by the sheer volume of information available. I was eager to learn, but I found myself tangled in what I now recognize as common myths. Some of these misconceptions had me questioning my skills, while others led me to make mistakes that could have been avoided with a little more clarity. Let’s dive into the myths that I’ve left behind and the truths that have shaped my ceramic practice.

Myth 1: All Glazes Are Created Equal

When I first started experimenting with glazes, I thought that they were interchangeable. I quickly learned that this couldn’t be further from the truth. Each glaze has unique properties based on its chemical composition, which affects how it interacts with the clay body during firing. For instance, I once tried to use a low-fire glaze on a stoneware body, thinking I could achieve a specific look. What I got instead was a dull, lifeless finish that left me frustrated. Understanding glaze types—earthenware, stoneware, porcelain—and their firing temperatures is crucial.

Myth 2: Dipping Glaze Is Just as Simple as Pouring It On

One might think that dipping glaze is as simple as submerging your piece into a bucket and pulling it out. However, I quickly discovered that technique plays a significant role in achieving the desired result. Too shallow a dip results in uneven coverage, while too deep can lead to drips and runs. After several trials and errors, I found that dipping for about 3 seconds provides a balanced layer of glaze. If I want a heavier coat, I’ll dip for 5-7 seconds, but I’ve learned to keep a close eye on how it interacts with my clay body.

Dip Time (Seconds)	Coverage Level	Notes
3	Light	Good for subtle glaze effects
5-7	Medium	Balanced coverage without drips
8+	Heavy	Risk of drips; requires careful monitoring

Myth 3: You Can’t Modify Glazes

One of the biggest surprises for me was learning that I could modify my glazes for different effects. Initially, I thought glazes were set in stone (pun intended!). However, I found that adjusting the ingredients could lead to fascinating results. For example, I once added a small amount of silica to a glaze to increase its glossiness. The outcome was stunning! I also learned about using different fluxes and colorants to create more vibrant or muted finishes. It’s all about experimentation and understanding the role of each component in your glaze recipe.

Myth 4: Firing Schedules Are One-Size-Fits-All

When I first heard about firing schedules, I assumed there was a universal method that worked for all clays and glazes. This couldn’t be more misleading. Each clay body and glaze combination requires a tailored firing schedule to optimize the results. For example, I often fire my stoneware at cone 6 and follow a slow ramp-up to avoid thermal shock. My firing schedule usually looks like this: 1. Ramp from Room Temp to 200°F (93°C) at 100°F (38°C) per hour 2. Hold for 30 minutes 3. Ramp to 2200°F (1204°C) at 200°F (93°C) per hour 4. Soak for 30 minutes before cooling This schedule has consistently delivered the best results for my stoneware glazes. Remember, it's essential to refer to the specific firing temperature for your glaze and adjust accordingly.

Myth 5: Glaze Results Are Always Predictable

As much as we wish for predictability in our work, I’ve come to accept that glazes can be unpredictable. Factors such as kiln atmosphere, humidity, and even the placement of pieces within the kiln can affect the final outcome. I remember a time when I was prepping for a gallery show. I had meticulously planned my glazes and firing schedules. Yet, one piece came out completely different from what I anticipated. Instead of crying over spilled glaze, I learned to embrace these surprises as part of the creative journey. Sometimes, the unexpected results can lead to the most beautiful pieces.
