The Experience
Recently, my husband and I decided to preserve our homemade jam using a paraffin wax seal. Inspired by his mom's old-fashioned method, we followed a straightforward tutorial on YouTube. Our jam turned out delicious, but we encountered a few issues with the sealing process.
We prepared 21 jars, applying two layers of wax with a five-minute interval between layers. The wax, about half an inch thick, turned slightly white as it hardened. Despite our efforts, I noticed some jam seeping between the jar and the wax in a couple of instances. Additionally, there were air pockets between the wax and the jam in some jars. For the jars with seepage, I quickly placed lids on them and stored them in the freezer.

What Went Wrong?
1. Seepage of Jam: This could be due to improper sealing or insufficient cooling time between wax layers.
2. Air Pockets: Air pockets can form if the wax does not make full contact with the jam, potentially leading to spoilage.
Ensuring Success with Paraffin Wax Sealing
Here are some tips to improve your paraffin sealing process:
1. Clean Jar Rims: Before applying wax, ensure the jar rims are clean and free from any jam residue. This will help the wax adhere better.
2. Proper Cooling: Allow the first layer of wax to cool completely before adding the second layer. This can take more than five minutes, depending on the room temperature.
3. Adequate Thickness: Ensure the wax layer is thick enough to form a good seal but not too thick to cause cracks as it cools.
4.Even Application: Pour the wax slowly and evenly to avoid air pockets.
5.Storage: For any jars with suspected sealing issues, storing them in the refrigerator or freezer can extend their shelf life.
