Every resin artist knows the feeling. You have a vision—a shimmering ocean scene, a delicate flower trapped in time, a paperweight that feels like a glass sculpture. But when you reach for your mold, you hit a wall.
The mold is too shallow. The petals float over the edge. The “deep pour” you bought barely covers a penny. You find yourself limited to flimsy, flat coasters that look like everyone else’s Etsy shop.
You aren’t alone. For years, crafters have been begging for a mold that offers depth without sacrificing clarity or flexibility. They wanted a canvas that could hold not just pigment, but objects.
Enter the game-changer: The Extra Deep Resin Coaster Molds Silicone (4 Inches Large, 6 Cavity).
This isn’t just another silicone tray. It is a 0.8-inch deep creative powerhouse designed to take your resin work from “homemade” to “heirloom.” Let’s dive into why this specific mold is about to become your most-used tool in the studio.
Part 1: The Depth Advantage (Why 0.8 Inches Changes Everything)
Most standard coaster molds on the market measure a mere 0.4 to 0.5 inches deep. That is enough for a thin layer of epoxy, but not much else. If you try to add dried orange slices, thick seashells, or resin doming, you end up with a messy overflow and wasted materials.
Our mold breaks the mold—literally. With a generous 0.8-inch depth, you aren’t just making a coaster; you are making a dimensional slab.
What does this depth allow you to do?
- Embed Larger Fillers: Have you ever wanted to preserve a whole rosebud? A large watch gear? A cluster of crystals? The shallow molds failed you. This 0.8-inch cavity welcomes those bulky treasures with open arms.
- Create Halo Stains: Halo stains (also known as petri dish effects) require a deep well of resin to allow the white and colored pigments to sink and spread properly. In a shallow mold, they hit the bottom instantly, creating a muddy mess. In this deep mold, they dance, bloom, and create stunning, galaxy-like rings.
- Thick, Luxurious Feel: A coaster that is 0.8 inches thick feels substantial. It feels expensive. When you pick up a finished piece from this mold, it has the weight and heft of high-end stone or thick glass. You aren’t just protecting a table; you are creating a piece of functional sculpture.
Part 2: Beyond the Beverage – True Versatility
The product title says “Coaster Molds,” but let’s be real: that is just where the fun starts. These 6 large cavities are rectangular canvases waiting for a new purpose.
1. The Wedding Flower Preservation
The most heartbreaking question in crafting groups is, “How do I preserve my wedding bouquet?” Standard shallow molds crush the petals. Our deep mold allows you to lay the flower flat, pour resin over it, and fully submerge it. The result? A stunning paperweight or memorial coaster that captures the actual volume of the flower.
2. Specimen Displays (The Curious Collector)
Do you have an entomologist in the family? Or a child fascinated by fossils? These molds are perfect for encapsulating interesting insect specimens (ethically sourced, of course), sea urchins, or fern fronds. The depth creates a magnifying glass effect, allowing you to view the specimen from all angles through the clear epoxy.
3. Keepsake & Memento Trays
Losing a pet is hard. Keeping their memory close is healing. Use these deep molds to create a memorial tray featuring your dog’s collar tag, a bit of fur, or a favorite small toy. Because the mold is 4 inches wide and deep, you have enough room to create a narrative—not just a lump of plastic.
4. The “Everything Else” List
- Soap Making: Cold process soap loves deep molds.
- Candle Making: Create large, 4-inch wide scented candles.
- Concrete casting: Make modern geometric plant saucers.
- Air Dry Clay: Use the mold as a forming tray for clay trinket dishes.
Part 3: The Technical Specs That Matter (Size & Volume)
Let’s talk math—because nothing ruins a resin pour like running out of mixed epoxy halfway through.
- Overall Mold Size: 8.6 x 13 x 0.8 inches
- Individual Coaster Diameter: 3.9 inches (The perfect “Goldilocks” size—not so small that a mug tips over, not so large that it hogs the coffee table).
- Volume Per Coaster: 5.56 oz of epoxy resin.
Why this matters: Knowing that you need roughly 5.6 oz per cavity allows you to mix efficiently. If you are pouring all 6 cavities, you need about 34 oz of resin. No guessing. No waste. Just perfect, professional pours every time.
Note: This mold is designed for casting resin and epoxy resin. Please do not use coating resin (which is thinner and designed to seal bar tops), as it may leak or cure unevenly.
Part 4: Quality That You Can Feel (Goodbye, Sticking Molds)
If you have been crafting for a while, you have experienced the nightmare: You wait 24 hours for your cure, you go to demold, and… the silicone tears. Or worse, the resin is welded to the mold because the interior was matte and rough.
The LET’S RESIN Difference
These molds are crafted from premium silicone that hits the sweet spot of flexibility and durability.
- Glossy Interior Finish: This is the secret weapon. The inside of each cavity is shiny and smooth. Why does that matter? Because your resin copies that finish. When you demold a coaster, it already has a high-gloss, glass-like surface. You don’t need to spend hours sanding and polishing with a drill attachment. Pop it out, trim the edges, and it’s ready to sell or gift.
- Flexible & Not Easily Deformed: Cheap silicone stretches out of shape like old taffy. This mold holds its round geometry. You can bend it, twist it to release bubbles, and it snaps right back to true form.
- Washable & Reusable: Resin is sticky. But cured resin peels right off this surface. Cleaning is a breeze—warm soapy water or a lint roller for dust before the next pour.
Part 5: The Do’s and Don’ts (Critical Troubleshooting)
Even the best mold fails if you misuse it. LET’S RESIN is confident in their product, but they want you to succeed. Here is the most important section of this article: Avoiding Resin Adhesion.
The Problem: Resin sticking to the mold (tearing the silicone).
The Cause: Heat damage or chemical incompatibility.
🔥 The Big “Don’t” 🔥
Do not use a lighter or blowtorch to remove air bubbles.
I know. Every YouTube video shows a creator waving a torch over a mold. But on deep or thick silicone, the intense heat degrades the polymer. Once the surface is scorched, the resin will chemically weld itself to the burned spot. You will pull the mold apart trying to get your coaster out.
✅ The Safe & Effective Solutions ✅
- Vacuum Chamber (The Best): If you are serious about resin, a vacuum chamber pulls bubbles out before you pour. No heat. No damage. Flawless results.
- Alcohol Spray: Fill a spray bottle with 91% Isopropyl alcohol. After you pour the resin and pop the surface bubbles with a toothpick, lightly mist the top. The alcohol breaks the surface tension and pops the bubbles instantly. Zero heat required.
- Heat Gun (Low & Slow): If you must use heat, keep the gun moving and stay 6 inches away. Do not linger.
Bonus Pro-Tip: For easy demolding, use a mold release spray or wipe the cavities with mild soapy water before pouring. This adds a microscopic barrier that makes the “pop out” incredibly satisfying.

Part 8: The Creative Prompt (Get Started Tonight)
Still on the fence? Let me paint a picture.
It’s Friday night. You mix 17 oz of Deep Pour Epoxy. You split it into three cups. One gets navy blue pigment. One gets white. One stays clear. You pour the navy into the mold. You drip the white into the navy. You swirl with a toothpick. You drop a handful of crushed glass and a gold leaf flake into the deep well. You spray with alcohol. One bubble pops. Two bubbles pop.
You walk away.
Saturday morning, you peel back the silicone. You lift out a solid, heavy, 0.8-inch thick disk that looks like the ocean floor frozen in time. The sides are straight. The top is glossy. The light hits the gold flake.
You didn’t just make a coaster. You made an artifact.
That is the power of the Extra Deep Resin Coaster Mold.
