What’s The Best Candle Mold Sealer?
Just about all candle molds have an opening in the bottom where the wick passes through. When it comes time to pour the hot wax into the mold, a leak at that hole can lead to potentially dangerous mess. Some form of candle mold sealer is what candle makers use to prevent leaks. It’s a simple but very important step. Trust me, once you’ve had a significant mold leak (and most candle makers will at some point) you become very interested in getting a good seal.
There are three main types of sealers: putty, plugs and magnetic. of the three, candle putty and plugs are used the most.
Candle mold putty is a soft, flexible slightly sticky material that seals the hole by sticking to the mold. As opposed to plugs, a candle maker could also use it to seal the joints in a complex mold that has multiple parts. The most common use is to seal the wick hole in a mold.
The main reason a mold leaks if you’re using putty is that the outside surface of the mold isn’t completely clean. Even a tiny bit of dirt or oil can prevent a good seal.
Even more challenging that dirt is wax. Obviously, is pretty common for molds to have some wax on them after they’ve been used a few times . If there’s a layer of wax on the mold, it may appear that the putty has adhered well. However, once you pour hot wax into the mold, that thin layer of wax will melt, break the seal and the mold will leak.
The take-home message? Double and triple check to make sure there’s no wax or dirt where you want the putty to stick.
Given a clean mold, using the putty is pretty straightforward. You position the wick in the mold, usually securing it in the bottom with the screw that comes with the mold (BTW – a wick screw can do a fairly good job of sealing the hole, but I wouldn’t count on it alone). With or without a screw, coil a tight spiral of about an inch of wick on the bottom of the mold and apply the putty over it.
Some candle makers to masking tape over the wick to prevent the putty from discoloring it . Just be sure the putty extends beyond the tape to make a tight seal with the mold.
Plug candle mold sealers are most commonly used in higher production operations. This has both advantages and disadvantages in comparison to using putty as a sealer. These details are explained at at Candle Mold Sealers so stop by there to learn more.
