Candles without wicks because you bought wickless candles or because the wicks disappeared in the wax (after you burned them)? There are kits where you get a new wick and then microwave the wax then pour the wax into the cup with the new wick. I guess the issue with your process is that you’d need a very thin pipe- nearly the exact size as the wick - otherwise the wick wouldn’t catch onto the wax because the fire couldn’t eat it 🤔 I think that’s what ur asking!!
