Embedding writing or printed images in resin can create stunning, long-lasting keepsakes. However, even mild heat can threaten the clarity and integrity of delicate text within your resin pours, making careful handling essential.
Why Heat Can Damage Embedded Writing
Paper, inkjet prints, and handwritten notes are particularly sensitive to heat. When resin cures, it releases heat (known as an exothermic reaction). Excess warmth, or external sources like heat guns or hot water baths, may cause inks to run or paper to warp. This can blur fine details and cause unwanted distortions in your embedded text.
Safe Casting Techniques for Text Embedding
- Pour resin in thin layers—2cm or less with products like “Trasparente”—to dissipate heat effectively.
- Allow each layer to cool completely before adding the next.
- Keep heat tools away unless absolutely necessary; instead, use a toothpick or let bubbles rise naturally.
- Always embed your writing only after confirming any print is thoroughly dry and, if needed, sealed with a clear barrier like spray varnish.
When This Matters Most
Minimising heat is vital whenever you’re preserving sentimental handwriting, certificates, or fine-printed scripts. Failing to do so may result in permanently blurred words or yellowing around the embedded material.
