Table Top & Art Epoxy (1:1 Ratio) for Hemisphere / Dome Mold Calculator
Pre-loads specific gravity (1.08) and 1:1 mix ratio to calculate exact Part A & Part B weights with cup scraping buffer.
A standard Hemisphere / Dome Mold (Ø10 cm minus 150 cm³ master) requires 130g (4.6 oz / 0.29 lbs) of Table Top & Art Epoxy (1:1 Ratio). Mix 65.2g Part A with 65.2g Part B (8% buffer included).
Casting Material & Volume Mode
Pre-loads specific gravity and 1:1 ratio by weight.
Geometry determines the container-volume formula. Use water displacement when the cavity is irregular.
Volume displaced by your master object inside the box.
Compensates for resin clinging to mixing paddles and cup walls (8% recommended).
Includes 8% waste buffer at SG 1.08

Step-by-Step Mix Ratio Derivation: Table Top & Art Epoxy (1:1 Ratio)
How displacement volume, specific gravity, and ratio split combine into final scale weights.
Calculates the empty fluid cavity by taking the gross 261.8 cm³ hemisphere containment volume and deducting the 150 cm³ displaced by the master model.
Multiplies fluid volume by the specific gravity of Table Top & Art Epoxy (1:1 Ratio) (1.08 g/cm³) plus an 8% buffer for cup scraping and pouring loss.
Distributes batch mass according to the exact 1:1 ratio by weight.
Engineering Specifications & Troubleshooting Guide: Table Top & Art Epoxy (1:1 Ratio)
Factory-tested parameters, common failure modes, and workbench best practices.
- High-viscosity, self-leveling coating epoxy designed for shallow pours up to 1/4 inch (6mm) max per layer.
- Mix ratio 1:1 by volume or 100A : 85B by weight. Always verify the manufacturer's exact weight-vs-volume spec.
- Produces a high-gloss, scratch-resistant glass-like finish on countertops, bar tops, and coasters.
Pouring deeper than 3/8 inch in a single pass; table-top epoxy will overheat, boil, and turn cloudy yellow.
