Cremation urns made from real stone or marble are special. Our customers select stone and marble urns for many reasons, including very practical ones having to do with the fact that they can serve the dual purpose of also being their own urn vault.

Stone urns are among the strongest and most long-lasting products we offer, but because they are made from genuine stone and marble, the lids are not threaded to the bodies of the urns. When you receive a stone urn from Stardust Memorials the lid will be "loose" from the rest of the urn and, after filling the urn, the decision will have to be made as to how to affix the lid to the body of the urn permanently.

Although it is tempting to reach for a product like Loctite CA or super glue to do the job, the truth is that there are other, and I think better, choices to consider. The problem with super glue adhesives is that the glue is thin and watery and will be absorbed by the stone when it is applied.

Loctite EpoxyWe recommend that you consider a household epoxy as an alternative solution for those who are looking for an absolutely permanent seal on a stone urn. The strongest and most durable epoxy solutions are two-part epoxies, which are chemically activated when the parts are mixed together. There are a number of brands available, and all of them are good -- Loctite makes an inexpensive, durable, easy-to-use one-shot called Loctite Quick Set Epoxy, which is available at any hardware or home improvement store.

When applying epoxy, keep in mind that even a thin layer, when it cures, will provide more than enough adhesion. For that reason, you will want to refrain from using too much on the lid, which could cause some of the epoxy to squirt out the side where the lid meets the body, resulting in an unwanted mess.

Silicone SampleThe other product option we recommend is regular silicone caulking, designed for kitchen and bath use. Unlike epoxy, a silicone seal can be broken-open if enough twisting force is applied to the lid. The advantage of this solution is that the lid will be strongly bonded to the body of the urn, but at the same time in the future -- should there be a reason to get inside the urn -- it will be possible to do so.

As with quick-dry epoxies, there are a number of silicone products available on the market. GE makes a good one -- GE Silicone II Kitchen and Bath Clear Caulk. One advantage of using a clear caulk is that, when dry, it will be nearly invisible, even if some of the caulk comes out of the side when the lid is pressed to the body of the urn.

Beyond these two simple, inexpensive products there are a number of adhesives specifically made to be used on stone (often sold in the same area of the store that sells granite countertops). These are truly industrial products with amazing strength and working properties, but are also expensive and for this purpose probably more than is really needed.
