Issue #92 - Boron Nitride Spray
March 31, 2016
Hot Out of the Kiln
Although Spring is here, it has been rather cool and rainy here is southern California.
This type of weather makes me sleepy, and that is a good thing since I have been having issues with getting to sleep at night.
I have been busy working on the next issue of the e-magazine.
I have decided to only offer it as a downloadable PDF file, since the sales for the CD were not that great and the work involved in turning the product into a CD is a lot of work.
The 2016 Glass Expo is occurring this week.
I know a lot of individuals who are attending and taking classes.
One of my friends will be there in spirit for me and taking lots of pictures.
If you attend and take pictures, please share them with me.
The Spring issue of the e-magazine is currently available on the Fused Glass Projects website.

Until next month…keep it hot!

Boron Nitride Spray
Boron nitride spray is also known as MR97 or ZYP.
This spray is a high temperature, anti-stick release agent for glass fusing, and is used for glass casting and slumping.
It is commonly used on metal or ceramic molds to keep the glass from adhering to the mold during the firing process.
I had heard about also spraying it on fiber board for fusing projects, but had not tried it myself.
I was doing a design and needed to place the glass inside a dam, so I decided to try spraying the fiber board with MR 97 before assembling the project.
Generally when you place glass inside a dam and take it to a high temperature, the glass not only sticks to the fiber board that is lining the dam, but also ends up with a lot of spiky edges.
I set up my dam and cut the fiber board to fit snugly inside the dam.
The fiber board pieces were then removed and taken outside for a nice spray of MR97
I followed the directions on the can and allowed the boards to dry before placing them back inside the dam.
Glass was then added to the project and the kiln was programed.
Once the firing was complete, the dam was dissembled and the fiber board easily removed from the glass.
I was really surprised at how well spraying the fiber board with MR97 or ZYP kept the glass from sticking and there were absolutely no spiky edges.

Have you been wanting to learn the hot craft of glass fusing, but don't know where to begin?
Whether you enjoy watching movies to learn the techniques, or having a book to refer to as you learn, these learning tools will assist you in your progress.
If you don't have access to glass fusing classes, or want to learn some of the techniques that are not generally taught at these instructional settings, look no further.
I am trying to add new and exciting information all the time, and these learning materials are the newest items added to the site to help others learn glass fusing procedures.

TIP - If downloading any of the downloadable movies, keep in mind that they are very large files.
If you purchase and want to download any of these large files, you might consider using a product like the Free Download Manager.
It is a free product that needs to be downloaded and installed on your computer.
It will increase the download speed and decrease the time required to download the product.
I'm hoping you can shed some light on this problem I just experienced. I have two Evenheat kilns. One that is 23-13 and one that is 8x7x7. I cooked a plant stake in the small one and 22 pieces of the exact size plant stake in the large one using the same programs. The ones in the large kiln came out quite a bit smaller and narrower than the one in the small kiln. I'm aware of the 1/4 inch rule but don't understand why the drastic size difference.

TIPS AND TRICKS:
While coating molds with MR97, shake the can well and keep it vertical while spraying. Spraying at an angle or upside down will cause you to only get propellant and not the mold release spray.

Coatings by Sandberg
MR97 is a Boron Nitride mold release spray that can be used on ceramic and stainless steel molds.
It can be used for projects where the temperature is no higher than 1800 degrees Fahrenheit.
Once you used any type of boron nitride mold release spray on a mold, it will no longer accept coatings of any traditional mold primer.
The spray provides a smoother texture on glass.
If you have used a Boron Nitride mold release previously on a mold, simple remove the old coating with a stiff toothbrush or a paper towel.
The can needs to be shaken well before applying.
Hold the can vertically and keep it about 10 to 12 inches away from the mold.
The first initial spraying takes two coats,
Once the first coating is applied wait about five minutes before applying the second coat.
The mold will be ready for use 15 minutes after the second application.
Future firings will only require a single coat of MR97.
