Salt dough ornaments can last anywhere from a year or two to several decades, primarily depending on whether they are properly sealed and cared for. If you seal your salt dough creations properly with a protective craft varnish, they can endure for many years, even decades! Without proper sealing, however, expect them to start crumbling and deteriorating within a year or two.
The Key to Longevity: Proper Sealing
The most critical factor determining the lifespan of a salt dough ornament is whether it has been adequately sealed. Sealing creates a protective barrier that shields the delicate salt dough from external elements.
Why Sealing is Essential
- Moisture Protection: Salt dough is highly susceptible to moisture. Humidity in the air, or direct contact with water, can cause the dough to soften, swell, and eventually disintegrate or grow mold. A sealant acts as a waterproof layer.
- Pest Deterrent: Unsealed salt dough can attract pests like insects or rodents, as it contains flour and salt. A hard, sealed surface makes it less appealing and accessible to them.
- Physical Durability: Sealing adds a layer of strength, making the ornament less prone to chipping, cracking, or breaking from minor impacts or handling.
- Prevents Crumbling: Over time, unsealed salt dough can become brittle and simply crumble apart due to environmental exposure and drying out unevenly.
Longevity Comparison
Here’s a quick overview of how sealing impacts the lifespan of salt dough ornaments:
| Condition | Expected Lifespan | Reason |
|---|---|---|
| Properly Sealed | Decades (20+ years) | Protected from moisture, pests, and physical damage by a durable varnish. |
| Unsealed | 1-2 Years | Vulnerable to humidity, mold, pests, and natural deterioration like crumbling. |
How to Maximize Your Ornament's Lifespan
To ensure your handmade salt dough treasures last for generations, follow these key steps:
1. Thorough Drying
Before sealing, it's crucial that your salt dough ornament is completely dry. Any residual moisture trapped inside will lead to mold growth, even if sealed.
- Air Drying: This can take several days to a week, depending on thickness and humidity. Flip ornaments periodically to ensure even drying.
- Oven Drying: For faster results, bake at a very low temperature (e.g., 200°F or 90°C) for 1-3 hours, or until hard and dry. Check frequently to prevent burning.
2. Choose the Right Sealant
For optimal protection, use a high-quality craft sealant.
- Craft Varnish: A popular choice, clear craft varnish (like Mod Podge or a clear acrylic varnish) provides a durable, protective finish. You can choose from glossy, satin, or matte options.
- Clear Acrylic Spray: An easy-to-apply option, clear acrylic spray sealants (e.g., Rust-Oleum Clear Gloss Protective Enamel) offer good protection. Apply outdoors or in a well-ventilated area following product instructions.
- Avoid using regular hairspray, as it is not designed for long-term preservation and can yellow or become sticky over time.
3. Proper Application
Apply the sealant carefully and thoroughly.
- Multiple Thin Coats: Apply 2-3 thin, even coats, allowing each coat to dry completely according to the manufacturer's instructions before applying the next.
- Cover All Surfaces: Ensure you cover the entire ornament, including edges and any intricate details, to create a consistent protective barrier.
4. Optimal Storage Conditions
Even sealed ornaments benefit from proper storage when not on display.
- Cool, Dry Environment: Store in a cool, dry place, away from extreme temperature fluctuations and high humidity. Attics, basements, and garages are often too humid for long-term storage of craft items.
- Protective Packaging: Wrap individual ornaments in acid-free tissue paper or bubble wrap and store them in airtight containers to protect against dust, physical damage, and pests.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can fade colors and degrade the sealant over time.
By following these preservation techniques, your cherished salt dough ornaments can become lasting heirlooms, bringing joy for decades.
