AMACO Wax Resist for Pottery 473 ml jar — Brushable Non-Toxic, ACMI Certified

AMACO Jar Wax Resist 16 FL Oz is a brushable, non-toxic wax that blocks glaze, slip, and underglaze on greenware or bisque to create clean unglazed areas and layered surface effects.

AMACO's jar wax resist is formulated for ceramicists who need a reliable way to prevent glaze adhesion in selected areas. Supplied in a 16 fl oz (472 ml) jar, this ACMI-certified, ASTM D-4236-compliant wax can be applied to greenware or bisque to reserve surface details, produce crisp lines, or prepare for resist techniques that reveal contrasting textures after firing.

How do I use this wax resist on my pottery?

Apply the wax directly where you want to keep glaze or slip from sticking. Use a soft brush for even coverage, allow it to dry thoroughly, then glaze over or around the treated area; the resist will lift or burn away during firing to leave the reserved surface exposed.

• Brush on to greenware or bisque for immediate resist protection
• Thin layers give better edge control; multiple coats increase resistance
• Dry fully before glazing to avoid smearing
• Fires out in kiln, leaving crisp unglazed areas

What types of projects benefit most from AMACO wax resist?

This wax resist works well for both functional and decorative ceramics where you want precise unglazed lines, reserved clay textures, or layered glazing effects. It's suitable for single-piece studio work as well as classroom demonstrations and small-batch production.

• Signature trim or foot rings left unglazed on functional ware
• Layered glazing where underlying colour must remain visible
• Pattern work and sgraffito that require protected areas
• Educational settings—non-toxic, safer to handle for students

Is the product safe and how is it packaged?

AMACO Jar Wax Resist is ACMI certified non-toxic and conforms to ASTM D-4236, making it appropriate for studio and classroom use with normal handling precautions. It comes in a 16 fl oz (472 ml) jar; AMACO also offers larger gallon sizes for heavier production needs.

• ACMI Certified Non-Toxic—suitable for studio and school use
• Conforms to ASTM D-4236 for art material labeling
• Available in pint and gallon jars for different usage levels
• Stored in a resealable jar to keep product usable between sessions

How should I store and clean up after using wax resist?

Keep the jar tightly closed and store at room temperature away from direct heat to preserve consistency. Clean brushes and tools with a suitable solvent recommended for waxes before the wax cures on bristles; once dry on ceramic, it burns away during firing so mechanical removal is rarely needed.

• Reseal jar to prevent skinning and contamination
• Use brush cleaner or solvent for immediate tool cleanup
• Allow treated ware to dry fully before glazing
• Wax burns out in kiln—no abrasive removal required post-fire

Who is this for? Ceramic artists, hobbyists, pottery instructors, and production studios who need a dependable, non-toxic resist for controlled glazing and decorative techniques will find AMACO Jar Wax Resist 16 FL Oz practical and easy to use. It fits small studios and classroom environments where safety, consistency, and clean results are priorities, and it's available in larger sizes for those doing higher-volume work.
