When jelly is canned using wax, several very thin layers of hot wax are poured over the cooling jelly. As the first thin layers cools, it pulls away from the jelly jar edges.
when you pour the second thin layer, you sort of rotate the high and low sides of the jar so that the wax goes into the empty edges. Layer after layer is poured so as to assure sealing the wax to the edge of the jar. Pouring a thicker layer just wastes wax and may not seal the jar.
This is not an approved method of canning or sealing jelly. However, it worked for years as the only method for some people. I hear it is not for long-term canning. But, I do know this was used for jelly for storage.This method would work for the Oui jars if you are canning jelly to give for gifts. This is one time you want firm jelly. You cannot can failed jelly and call it ice cream topping with wax on top.
WM sells the 1 lb, box of Gulf Wax for $3.12 (I checked), but I bought my Gulf Wax blocks for a quarter for one pound at yard sales. If you think it is dusty, just scrape the outside with a knife until you get to "new" wax, You only need something to melt the wax in. I would put a cup in a pan of water to avoid melting wax in a pot and having it pop and catch on fire.
For the life of me, I cannot get a Oui jar photo to put on the blog that does not go right over the Gulf Wax photo. It must be a blog thing because nothing works.
Gulf Wax is another memory from my early childhood. My family received jars of jelly sealed with wax. By rinsing the jelly covered wax, the wax can be reused to seal more jelly. When I first married, a woman gave me a regular glass of jelly sealed with wax.
Like I said, this is not an approved method. If you are just making jelly to give for Christmas, in my opinion this will be fine for a few months. I might even eat the jelly after many months.
Other repurposing of Oui jars is available if you do not want to can jelly.
Have you ever seen/used jelly sealed with wax? Have you ever sealed jelly with wax?
