Paul's 10 Commandments of Fused Glass

  1. Glass fusing experience is measured by number of kiln firings, not years. You get double credit for experimenting – which you should do continually. Your glass scraps and kiln shelf margins can teach you more than any class or book.
  2. Your success (or failure) is a product of two things: What you do at the table AND how you fire it. Until you are programming the kiln you are at the mercy of the person who is.
  3. No matter how experienced you are, how smart you are or how lucky you are, your work will occasionally break during firing. Take the time to understand what went wrong and don’t mourn the shards of glass in your kiln. They will make nice jewelry for your mother-in-law.
  4. Avoid any teaching studio that doesn’t fully explain firing schedules, annealing, thermal shock, and devitrification in their beginner class. Anyone who doesn’t have a deep understanding of these things has no business teaching glass kilnforming.
  5. The pen and digital camera are indispensible tools for the fused glass artist. Take pictures and notes of what you do and the results. Even if your memory is great today it won’t always be that way. If you don’t believe me, ask anyone (else) who is over 40.
  6. As you learn, share your knowledge. If you think you’ve invented something new you almost certainly haven’t. If the value of your work is founded on a proprietary technique then you may be a good technician but that doesn’t make you a good artist.
  7. Almost all fused glass failures are caused by doing something faster than you should have done it.
  8. Use long, slow bubble squeezes generously. The kiln gods love the temperature range between 1100° and 1250° F and they will reward you for languishing there on the way up.
  9. Anneal for a thicker piece of glass than you are firing. Most published schedules are based on math that assumes the glass is cooling evenly from all sides. This assumption is false since glass cools more slowly where it rests against the kiln shelf.
  10. The secret to being a successful glass artist is to approach fusing like you would sex: compatibility matters, use good hygiene or you’ll end up with something cruddy, slower is always better, treat the glass with respect or it will hurt you, and you know it was a success if there is no stress when you are finished.

I miss Helios!


Southie2009 Thank you Paul.


Thank you Paul. I have been looking for a interactive website sharing information on fusing. I have books on fusing and a little experience. I am mainly a lampworker. I dont use the torch when the weather is too cold or hot and I want to keep the glass art going. I will be checking out the whole website. Thanks again.Smile

10 Commandments

Hi Paul, I'm brand new to the site and the first thing I read is the 10 commandments.  You are absolutely right I will use it for my next beginners fusing class.  Thank you.  What's extra nice is it taught me a bit about sex as well!  Tio

Diann Bartnick.....the

Diann Bartnick.....the Comandment that says to WRITE DOWN everything you do in making fused glass is the most important for me as I have discovered some really cool results coming out of the kiln and sometimes try and duplicate no avail.  There was one little detail that I obviously omitted and, darn, if I can remember what that one ingrediant was.

Top Ten

Hey Paul,

I love this. I took a beginners Class and they didn't teach us anything about firing. We just glued up a project and left, the next day it was done. So,I bought a book and started to play. Had a few really bad mistakes(make sure your glass is dry) and some really great ones. What I did learn was to keep a journal, so you don't make the same mistake over and over again. Now I tell the people that want me to teach them, I just know enough to be dangerous. Buy the book!! But now I want to learn about cold working. Which is the best book?

Love the tenth commandment

Paul - I love these ten comandments - especially the last one.  I always new there was a strong relationship between fused glass and sex - now you have made it all very clear... lol


Ten Commandments

Totally agree with you, especially about taking pictures and notes.  I tell all my students to

take before and after pictures and to document everything.  As an instructor I always take

a picture of all the work in the kiln before firing and then upon completion.  Sometimes my students don't even recognize the finished product until I show them their "before" shot.  All very good advice for all instructors.  Thank you.


These are GREAT and so true.  I laughed out loud at #3.

Oh am really understanding

Oh am really understanding your words - am enjoying the journey!!! Thankyou!

I think no 7 belongs in no 10

I am brand new to the site.

I am brand new to the site. I read the introduction on spam and it Looks like you DO have some irrelevant or inappropriate messages (spam) on this page by some users.


Lots of old posts on here. Where is everybody gone. I really like the website even though it can be very slow getting to links at times. I have had to change password three times now to get in to the system. It keeps saying my user name and or email address is not recognized. Hope it gets corrected because there is lots of great infomation here to read.
