CeraTex 3170 Ceramic Fiber Paper 1/8″ Thick
The CeraTex 3170 fiber paper is designed for high-temperature insulation in kilns, stoves, furnaces, and glass fusing setups. It offers a temperature rating up to 2300 F and provides excellent insulation properties. The material is chemical and flame resistant, supporting durable use in demanding firing cycles. Its 1/8″ thickness makes it suitable for liners and gaskets, reducing heat loss while helping maintain even temperatures during fusing.
Bullseye ThinFire Kiln Shelf Paper
ThinFire is a ceramic-impregnated shelf paper designed to separate glass from kiln shelves effectively. It is lighter than many ceramic fiber options, which reduces binder burnout odor and helps produce a glossier shelf-side finish. This paper serves as a practical alternative to shelf primers, while delivering a smooth, clean surface for glass pieces and jewelry that rest on the shelf.
10 Pcs Kiln Paper Ceramic Fiber 11 x 12
This package includes ten 11×12 inch ceramic fiber papers, each 0.12 inches thick, rated up to 2300 F. The sheets are designed to provide reliable insulation for glass fusing and other high-temperature applications. The variety of replacements in a single purchase helps maintain consistent firing conditions across multiple projects and reduces downtime between sessions.
Honoson Thinfire Kiln Shelf Paper Roll
This roll provides a long, continuous sheet of 20″ wide kiln shelf paper, ideal for custom-fit shelf preparation in glass fusing. It withstands temperatures up to 2300 F and offers decent heat insulation to keep firing stable. The generous length (65 feet) supports a range of projects, while being easy to cut and shape for beginners and skilled crafters alike.
Ceramic Fiber Paper 2300F Rated 1 mm Thick
The SIMOND STORE ceramic fiber paper is rated for 2300 F and features asbestos-free composition with strong chemical resistance. The 1 mm thickness provides solid insulation without excessive bulk, making it suitable for gaskets, liners, or insulated sections within kilns or stoves used for glass fusing.
AOQIVIS High Temp Gasket Paper 11x12x0.12
AOQIVIS offers 11×12 inch sheets with a 0.12 inch thickness, packaged as a ten-piece set. Made from high-temperature ceramic fiber, these sheets deliver reliable insulation for a variety of glass fusing and kiln applications. The set is designed for multiple uses in projects that require consistent thermal management and durable performance.
100 Sheets Round Microwave Kiln Papers 4.7 Inch
Jutom’s round kiln papers are designed for single-use applications in small glass fusing projects. Each 4.7 inch round sheet helps prevent sticking and supports clean finishes for delicate pieces. The pack includes 100 sheets, providing ample supply for small studios and hobbyists working on multiple pieces.
Buying Guide: Key Purchase Considerations For Fiber Paper For Glass Fusing
- Temperature rating: Most glass fusing projects require papers rated at 2300 F or higher. Verify the maximum temperature to match your kiln and firing schedule.
- Sheet thickness and format: Thicker papers offer stronger insulation but may be less flexible for curving or shaping. Shelf papers, rolls, and gasket sheets suit different setup needs.
- Insulation quality: High insulation reduces heat loss and can improve firing consistency, influencing fuse quality and energy efficiency.
- Chemical and flame resistance: Materials that resist chemical degradation and flare-ups prolong kiln life and prevent contamination of your glass.
- Ease of use and handling: Lightweight papers or pre-cut sheets simplify setup and reduce handling wear, particularly for beginners.
- Size options: Choose sheets or rolls that fit your kiln shelves or specific project dimensions to minimize waste.
- Cost and replacement rate: Consider the price per sheet or per foot and how quickly you’ll replace worn papers during ongoing projects.
- Asbestos-free and safety: All listed options aim to be asbestos-free and safe for hobbyist studios and professional shops.
When selecting fiber paper for glass fusing, balance insulation performance with project-specific needs such as size, thickness, and ease of handling. Cross-reference your kiln type, shelf configuration, and pattern complexity to determine which paper format—sheet, roll, or round disk—will deliver the most consistent results across multiple firing cycles.
