Glass Resources

At Jen-Ken Kilns, we want to support every glass artist—from curious beginners to seasoned kilnformers—with the best information available. Two of the most trusted and generous sources of glass education in our industry are Bullseye Glass Co. and Slumpy's, whose Research & Education team has spent decades publishing high-quality technical guides, firing insights, creative tips, and project ideas for kiln-formed glass.

Bullseye’s TechNotes and TipSheets and Slumpy's Firing Schedules, in particular, have become foundational learning tools for artists around the world. With their permission to share links to these resources, we’ve created this convenient index so you can quickly find the articles most relevant to your work.

We encourage you to explore Bullseye’s complete library directly on their website as well—it's an incredible, continually updated knowledge base for anyone working in warm glass. You can browse the full collection here:

As our own resource hub grows, we’ll continue adding guides, firing charts, tutorials, and references from a variety of respected educators and organizations across the glass community.

We’re proud to begin by highlighting Bullseye and Slumpy's outstanding contributions to kiln-glass learning.
