🔥 1. 魅力の本質

レジンダイス制作

There is a profound, almost alchemical magic in watching clear liquid resin transform into glass-hard, light-refracting polyhedral gems. Resin dice casting combines the tactile satisfaction of chemistry with the expressive freedom of fine craft, allowing maker-gamers to capture nebula swirls, metallic shimmers, and suspended mysteries inside functional art pieces. Stirring raw liquid components and carefully pouring them into silicone chambers sparks an intoxicating anticipation that builds over the twenty-four hours required for curing.

Demolding a fresh batch of dice provides an instant rush of tactile and visual satisfaction. Peeling back flexible silicone to reveal smooth, cold, gleaming facets produces an addictive high unique to hand-cast resin art. Beyond the creative thrill, crafting your own custom dice injects personal story and unique weight into every tabletop roleplaying session, turning simple gaming tools into prized handmade heirlooms.

🗺️ 2. 全体像と種類

Before investing in workshop equipment or specialized tools, it helps to understand how different casting techniques shape both the process and final clarity of your dice.

Cap-Mold Epoxy Casting (Accessibility & Crafting Fundamentals)

Focuses on using flexible silicone cap molds and slow-curing epoxy resin to pour single-color or swirled dice using basic manual bubble-mitigation techniques.

Pressure-Cure Vacuum Casting (Glass-Grade Clarity)

Employs sealed pressure pots to subject curing resin to 30 to 40 PSI of air pressure, shrinking internal air bubbles until they become completely invisible to the naked eye.

Master Sculpting & Inclusions (Bespoke Artistic Expression)

Focuses on casting custom 3D-printed masters, embedding tiny miniatures, dried flowers, or sharp-edged inclusions into multi-stage pours for high-end collector dice.

💡 おすすめ

For complete beginners, a simple two-part 1:1 epoxy resin kit with premade silicone cap molds is universally recommended: this affordable setup lets you master mixing ratios, color swirl timing, and basic demolding without the financial commitment of pneumatic pressure pots.

Casting Your First Swirled D20 (Your Day-One Victory)
Today is all about mastering precise chemical measurements and bubble-conscious pouring to create a single pristine 20-sided die.

1

Measure and Mix

Measure equal parts A and B epoxy resin into a silicone cup, stirring steadily with a flat stick for three full minutes while scraping the sides to eliminate unmixed streaks.

2

Infuse and Swirl

Divide the resin into two cups, add one drop of alcohol ink to one cup, wait three minutes for surface bubbles to pop, then gently pour the colored resin back into the clear base without fully mixing.

3

Slow High-Pour

Warm the resin cup briefly in a warm water bath to thin it, then pour a slow, hair-thin stream into your D20 silicone mold to help air bubbles pop on the way down.

4

Cap and Cure

Lightly spritz the resin surface with isopropyl alcohol to pop remaining bubbles, set the silicone cap at an angle to bleed excess liquid, and let it cure undisturbed for 24 hours.

🏆 1日目の達成ゴール

Once you peel back the silicone cap to reveal a smooth, glassy D20 with suspended color swirls, you have officially conquered day one.
