Studying Glaze Chemistry


Understanding glaze chemistry has never come easy to me.   I have to work very hard for it to sink in and make sense.   In the past I avoided putting in the time to learn the science behind making glazes, even though I really had an interest.   There are so many varibles, it's easy to over-think the process and make it more complex than it needs to be.

Yesterday I woke up with thoughts of glaze testing consuming my mind.  I got out the Glaze Master Guide and with much determination I worked my way through the program.  To help me better understand some of the chemistry concepts I referred to the books "Mastering Cone 6 Glazes" and "The Complete Guide to High-Fire Glazes". 


Learning about the "Seger Unity Formula" is a hurdle that I'm still struggling to fully understand.  I'm not good at just accepting a concept, I always think deeper and want to know why.   I'm learning that sometimes I just have to accept the concept and trust that the why will reveal itself as I continue to study glaze.

I cracked open John Britt's "Understanding Glazes" DVD. The DVD is a great intro to glaze chemistry.  
John gives a quick run through of different ways to test. He simplifies what glaze is chemically.  He talks about many individual chemicals, explaining what category they belong and a brief about what they do.  
GLAZE
* Glass former =  RO2 
*Melter / Flux = RO, R2O
*Stabiliser / Refractory = R2, O3


10 hours later I had a much better understanding of all the things I still need to learn. Ha! 

My glaze journey has just begun.

Happy Glaze Day!
