How to Use This Calculator

Enter the total volume of your mold cavity in cubic inches (length × width × depth for a rectangular mold).
Measure or estimate the total volume of the objects you are embedding and enter that in cubic inches.
Enter the resin density in g/cm³ from your product datasheet (most epoxies are 1.0–1.2 g/cm³).
Read the net resin needed in ounces (with 10% overage) — this accounts for the space the objects displace.
Use the exact resin oz and gram weight to measure your resin and hardener precisely before mixing.

How the result changes with Mold Volume

Mold Volume: Total interior volume of the mold in cubic inches. For a rectangular mold: length x width x depth.
Embedded Objects Volume: Total volume of all objects being embedded. Estimate by water displacement or by approximating each object as a simple shape.
Resin Density: Density of your mixed resin. Most epoxies are 1.05-1.15 g/cm³. Check your product data sheet for exact value.
