Why Choose ThinFire Instead of Kiln Wash

• Smoother finish: reduces shelf texture transfer

• Time saver: skip mixing, applying, and drying release

• Predictable: consistent thickness sheet to sheet and roll to roll

How to Use

1. Start with a clean, dry kiln shelf. Do not apply kiln wash on top of ThinFire.

2. Place ThinFire with the rough, printed side against the shelf and the smooth, plain side against the glass. Avoid overlaps and wrinkles.

3. Load glass on the paper and keep the shelf level for even contact.

4. Fire using your normal schedule for the glass and project type.

5. After cooling, lift the project and discard the used paper.

6. Wipe remaining residue from the shelf with a damp cloth or HEPA vacuum. Avoid breathing dust.

7. For deep or highly textured molds, a brush-on separator kiln wash may be a better choice.

Best Practices

• Store flat, clean, and dry in the original bag or a sealed container
