Real-world stress testing for sealants used on cement and gypsum candle vessels

Whether you’re developing a new sealant or refining an existing formula, this testing service is designed to push your product to its limits—so you can confidently stand behind its performance.

What’s Included:

• Three Material Types Tested: Cement All, Hydrostone, and Jesmonite

• Candle-Filled Vessel Testing: Each vessel is filled with a coconut-blended wax known for its thin consistency and high-heat burn, paired with thicker wicks for maximum heat output

• Extreme Heat Conditions: Jars are burned to reach up to 175°F external temperatures — significantly above standard to simulate potential user misuse

• Multi-Stage Burn Process:

  • 4-hour standard burn

  • 8-hour extended burn

  • Full-power burn to self-extinguish

• Detailed Written Report: Includes performance notes at each stage: sealant durability, curing quality, wax interaction, heat resistance, and safety considerations

This is not a surface-level test — it’s a stress test built to reflect how real customers might use (or misuse) your product. Perfect for developers focused on clean, safe, and compostable solutions.

Fee: $250
Note: Each test includes the creation of brand-new vessels specifically for this process. Turnaround time varies based on vessel production, curing, and full burn testing. Testing begins once the product is received and scheduled into the workflow.
