PAPYROS®
KILN SHELF LINER
What people are saying about Techniglass…
“I love Papyros and use it often in my work and in classes. Many of my students have switched from other brands of firing paper to Papyros because it’s the only brand I trust. It is perfect for fusing on the kiln shelf and in casting molds. In my studio, I am able to fire Papyros more than once with the assistance of suction cups to transfer my pieces onto and off of the paper. In a side by side comparison of firing papers, Papyros is superior and is now the only firing paper I keep in my studio. I love the fact it has a smooth and smoother side so that I can choose my texture. I bring Papyros to my classes because I genuinely love using it!”

FEATURES
Reduce Prep Time
No need to mix or stir the primer, buy or clean an applicator brush. No need to wait for the fusing primer to dry between shelf coatings. Just cut PAPYROS to shelf size, place on the shelf, insert into the kiln and start firing!
Achieve Exceptional Separation
A single layer of paper will prevent glass from sticking to the shelf at full fusing temperatures.
Reduce Air Bubbles
PAPYROS is porous, allowing air to circulate. This reduces the probability of air bubbles from forming between the glass and kiln shelf.
Reduce Breakage
When shelf primer is applied unevenly, glass may stick to bare or unevenly coated areas during expansion. When this happens, glass can pull apart and break. PAPYROS ensures an even coat between the glass and kiln.
Protect & Maximize Kiln Shelf Life
PAPYROS protects and prolongs the kiln brick shelf life.
Fast & Easy Clean-Up
PAPYROS is quite durable, and tends to retain its paper-like qualities during firing, rather than decomposing into loose dust. This allows for fast and easy clean up.
Wide Variety
Available in a wide range of sizes and formats for the hobbyist or professional artist.
INSTALLATION & USE
Cut Sheet
Cut Sheet a minimum of 1/2″ (13mm) larger than the glass piece.
Place in Kiln
Place sheet on kiln shelf, then place piece of art directly on PAPYROS.
Fire
Fire art in usual way.
Remove from Kiln
Once glass has cooled, remove it from the shelf. If necessary, rinse off paper residue with water.
To Use:
Line the entire shelf, or cut a piece of PAPYROS measuring at least 1/2″ larger than your project (on all sides), then place your glass project(s) on the papered shelf and fuse as you would normally.
To Clean Up:
When you’ve decided that you’re ready for a new piece of PAPYROS, follow the Safe Handling instructions listed below to dispose of the expired paper.
NOTE: If using a Shop Vac, ensure that your HEPA filters are changed on a regular basis so vacuum functions correctly. When using a trash basket, make sure you use one dedicated for paper disposal that has a fitted lid and is lined with a plastic bag. Empty trash bags on a regular basis.
Safe Handling:
Always follow these basic safety steps:
- Wear gloves when handling.
- Avoid breathing residual dust when cutting pre-fused PAPYROS, or cleaning post-fired PAPYROS from your kiln shelf.
- Wear a respirator that is NIOSH-approved for dust when working with PAPYROS.
- Wear safety glasses with side shields.

Frequently Asked Questions
CUTTING - Can I cut the paper to size?
Yes, you may cut Papyros to any size with an ordinary scissor or cutter.
COMPOSITION - What is Papyros made of?
Papyros is ceramic based and perfectly compatible with ceramic kilns. Request an MSDS for details.
TEMPERATURE - What temperature can Papyros withstand?
Papyros can withstand up to 1600F/872C.
RESIDUE GLASS - Will Papyros leave any residue on glass?
Papyros ensures an even coat between glass and kiln paper to retain its paper-like qualities during firing. Just gently lift the glass piece off of the kiln paper.
SIZES - What are the available sizes of Papyros?
Papyros is available in many dimensions of length and width. Please see the below table to choose what best fits your application:

COMPATIBILITY - Is Papyros compatible with all types of glass?
Due to its sturdy composition, Papyros provides excellent glass/kiln shelf separation on the first use and often in subsequent firings, as well. How long post-fired Papyros retains its integrity depends on the type of glass used on the project underside (Opal vs. Transparent), the nature of the project (volume/construction), as well as the final fusing temperature (degree of glass movement in the kiln).
LAYERING - How many layers should I use to separate glass in the kiln?
Only one layer of Papyros Kiln Paper is necessary for firing. Our specially designed paper will prevent glass from sticking to the shelf along with other glass while in the firing processes.
RESIDUE - Will Papyros stick or leave a residue in my kiln?
Papyros will not leave any residue in your kiln as it is easy to remove and clean up. After the glass is fired, remove the Papyros release paper by carefully folding over the paper with a studio dedicated spatula. Carefully dispose of it into a trash basket and close the lid. If using a vacuum, be sure to use one equipped with a HEPA filter. If necessary, rinse off the paper residue from the art object with water.
SAFETY - Is Papyros safe to use?
It’s important you use basic safety practices while using any kiln shelf release paper including Papyros. Wear gloves while handling kiln paper, avoid breathing residual dust when cutting pre-fused or post-fired Papyros paper, wear a respirator that is NIOSH-approved for dust, and wear safety glasses with side shields. Also, remember to keep the room where your kiln is stored clean to ensure safe conditions.
CURLING - Do the edges of Papyros curl during firing?
No. During testing by our engineers, we found that Papyros paper remained flat on the kiln shelf, even when fusing a circular project on a square sheet. We experienced no instances where the edges of the kiln paper were curled upward.
CORRECT SIDE - Does it matter which side of the paper is up or down?
No, both sides of release paper perform virtually the same. It is a user preference.
OPAL GLASS- Does Opal glass have a smoky film residue upon firing?
If opal glass has a residue, try the below to correct for your current of next firing.
a. Set temperature below 1450; 1420/1410 for Wissmach and System 96
b. Rinse or sand the residue off.
