Alumilite Deep Pour vs Nicpro Crystal Clear: Which Epoxy Is Best for Jewelry Casting?
Last updated September 01, 2026 · Data from manufacturer TDS and market pricing
Summary
Alumilite Deep Pour and Nicpro Crystal Clear serve different niches in the jewelry and craft casting market. Alumilite Deep Pour is a low-viscosity (300 cps) deep pour epoxy that cures in 48 hours, making it ideal for thicker jewelry pieces, paperweights, and encapsulated objects. Nicpro Crystal Clear is a 1:1 tabletop-style epoxy with 900 cps viscosity, optimized for thin jewelry pieces like pendants, earrings, and coasters. Alumilite offers deeper pour capacity and faster overall cure, while Nicpro offers simpler measuring (1:1 ratio) and is more beginner-friendly for small craft projects.

Verdict
Choose Alumilite Deep Pour when you need to cast thicker jewelry pieces, embed objects in deep molds, or create paperweights and larger castings. Its 2-inch pour depth and 48-hour cure allow for substantial pieces with minimal layer work. Choose Nicpro Crystal Clear when you are making thin jewelry pieces (pendants, earrings, keychains), coating small objects, or working on craft projects that don't require deep pours. The 1:1 mix ratio is easier to measure accurately, and the lower cost makes it ideal for beginners and high-volume craft production.
Frequently Asked Questions
Can Alumilite Deep Pour be used for thin jewelry pieces?
Yes, Alumilite Deep Pour works well for thin jewelry pieces, but it is overkill for most applications. The 2:1 mix ratio requires more careful measuring than 1:1 systems, and the longer cure time (48 hours) means slower project turnaround. For thin jewelry under ⅛ inch, a 1:1 tabletop epoxy like Nicpro is more practical and cost-effective.
Is Nicpro epoxy food safe for jewelry?
Nicpro Epoxy Resin is non-toxic when cured and safe for skin contact as jewelry. However, it is not FDA-certified for food contact. For jewelry that will have incidental food contact (like serving utensils), choose a certified food-safe epoxy. Always allow the full 7-day cure before any skin or food contact.
Which epoxy has better UV resistance for jewelry?
Both have basic UV stabilizers suitable for indoor use, but neither is specifically formulated for prolonged sunlight exposure. Alumilite Deep Pour has slightly better UV resistance due to its deeper pour formulation. For jewelry that will be worn outdoors frequently, consider adding a UV-resistant topcoat or choosing a product with enhanced UV stabilizers.
Can I use molds with either of these epoxies?
Yes, both work well with silicone molds. Alumilite Deep Pour's lower viscosity (300 cps) allows it to flow into intricate mold details more easily, making it better for detailed molds and complex shapes. Nicpro's higher viscosity (900 cps) is better for surface coating and simple mold shapes where you want the epoxy to stay in place without overflow.
