Handmade resin pyramids look beautiful when finished – glossy, clear, and often filled with crystals, flowers, or metallic flakes. However, behind every perfect pyramid is a long list of problems that most makers will face at some point. Working with resin is far from simple, and pyramid moulds in particular can be surprisingly difficult to master. This blog explores the most common issues that arise when making handmade resin pyramids and why they happen.
Air Bubbles: The Most Common Problem
One of the biggest challenges in resin pyramid making is air bubbles. Because pyramid moulds come to a sharp point at the top, air easily gets trapped inside. Even when the resin is poured slowly, bubbles can cling to the edges or rise too late, leaving visible marks once the resin cures.
Many beginners underestimate how stubborn bubbles can be. Heat guns and blow torches help, but using them incorrectly can cause more harm than good, such as burning the resin or warping the mould. Without a pressure pot or vacuum chamber, achieving a perfectly clear pyramid can be extremely difficult.
Uneven Curing and Soft Spots
Another frequent issue is uneven curing. Resin needs accurate measuring and thorough mixing to cure properly. If the resin-to-hardener ratio is slightly off, parts of the pyramid may remain sticky or soft, even after several days.
Pyramids are thicker at the base, which means the resin can cure at different rates throughout the piece. This can lead to internal stress, cloudiness, or soft spots that ruin the final product. Temperature also plays a major role – cold rooms slow curing, while overly warm environments can cause the resin to cure too quickly and crack.
Layers Going Wrong
Many resin pyramids are made in layers, especially when including objects such as crystals, flowers, or symbolic designs. Layering introduces a whole new set of problems. Pouring the next layer too soon can cause colours to bleed or objects to sink. Waiting too long can result in visible lines between layers that spoil the clean look of the pyramid.
Dust is another issue during layering. Even a tiny speck can become painfully obvious once trapped inside clear resin. Keeping a dust-free workspace is harder than it sounds, especially for home-based makers.
Mould Issues and Demoulding Damage
Silicone moulds do not last forever. Over time, they can lose their shape, develop tears, or become cloudy, which affects the finish of the pyramid. A damaged mould often leads to warped edges or dull surfaces that require heavy sanding and polishing.
Demoulding is also risky. If the resin has not fully cured, removing the pyramid too early can cause bending or fingerprints. Removing it too late can make the piece difficult to release, increasing the chance of cracking the sharp pyramid tip.
Surface Imperfections and Finishing Problems
Even when a pyramid comes out of the mould, the work is not always finished. Surface imperfections such as scratches, dull patches, or uneven edges are common. Fixing these issues requires sanding through multiple grits and polishing, which is time-consuming and physically tiring.
Polishing resin pyramids evenly is especially tricky because of their shape. Flat surfaces are manageable, but sharp edges and pointed tips are easy to over-sand, permanently altering the design.
Health and Safety Concerns
Resin work comes with health risks that are often overlooked. Resin fumes can be harmful without proper ventilation, and prolonged skin contact can cause irritation or allergic reactions. Wearing gloves, masks, and working in a well-ventilated space is essential, yet many hobbyists struggle to maintain these standards consistently at home.
Spills are another hazard. Resin sticks to almost everything, and cleaning it up incorrectly can spread the mess further rather than remove it.
Time, Cost, and Wasted Materials
Handmade resin pyramids are expensive to produce. Resin, pigments, moulds, and tools all add up, and mistakes often mean wasted materials. A single failed pyramid can represent hours of work and a significant financial loss.
Resin also has a limited working time, so rushing to avoid waste can lead to careless errors. This balance between speed and precision is one of the most frustrating aspects of resin crafting.
Conclusion
Making handmade resin pyramids is both an art and a technical challenge. While the finished pieces can be stunning, the process is full of potential problems, from air bubbles and curing issues to mould damage and health risks. Success requires patience, practice, and a willingness to learn from failure. For many makers, it is precisely these challenges that make resin pyramid crafting so rewarding – every flawless piece feels like a hard-earned achievement.
