Make Candles in Vintage Glassware: A DIY Step-by-Step Guide

I started making candles in vintage glassware because I had collected an assortment of glass dishes for parties and never used most of them. I burn candles every day, so repurposing these beautiful thrifted pieces into candles felt obvious. They’re plentiful at thrift stores and antique malls—each one a little waiting to be turned into something special.

Using vintage glass gives each candle instant charm. A well-chosen vessel elevates a homemade candle so it looks more expensive than store-bought versions.

This idea follows the same philosophy as my oil candles and terracotta votives: the container contributes a lot to the overall appeal.

Finding the Right Vintage Glass

Choose sturdy pieces such as sugar bowls, candy dishes, heavy pressed glass compotes, and lidded containers—lids look beautiful with candles. Always pick up a piece before buying: it should feel substantial and heavy rather than delicate.

Look for shapes that open at the top rather than narrowing, and aim for at least a couple of inches of depth. Examine the glass in good light and turn it to check for chips and hairline cracks.

Avoid crystal and lead crystal, thin blown glass, any piece with interior paint or gilding, and anything precious or irreplaceable you’d regret breaking. If a vessel can’t handle heat, it isn’t worth the risk.

The Heat Test

This is a crucial step many people skip. Glass can crack from sudden or sustained heat, so I always do what I call a “heat shock” test before pouring wax.

Do this in the sink so any breakage happens in a contained place. Set the clean, dry, room-temperature vessel in the sink and fill it with near-boiling water. Let it sit for five to ten minutes, then drain and immediately run cold water over it to shock the glass. Inspect it carefully in good light—no cracks, no hairlines, and no dull or uneven sounds when you tap it.

If the glass cracks during this test, you’ve avoided a messy and potentially dangerous failure while saving money and time.

Remember: home tests reduce risk but don’t guarantee safety. Burn candles on a heat-safe surface, never leave a burning candle unattended, and stop burning when about half an inch of wax remains.

A Few Favorite Blends

Blending two or three fragrances creates unique scents. Some combinations I enjoy: a spruce and fir pairing for a fresh forest scent; mint with rosemary, sage, and a touch of orange blossom or jasmine for a garden-like green blend; and a banana nut bread base with cardamom and cinnamon for a warm, spiced aroma. Experimentation with small test sticks helps you refine each combination before committing a full batch of wax.

Eden’s Tips

Always do the heat test in the sink before pouring wax. Test fragrance blends on sticks so you don’t waste wax. Weigh your fragrance rather than estimating—a small scale makes a big difference. Allow candles to cure for a few days before burning.

For the first burn, let the melted wax pool to the edges—usually two to three hours—to avoid tunneling. Trim the wick to a quarter inch before every burn to reduce soot and flicker. When a candle is finished, pour boiling water into the vessel to melt and remove the remaining wax, then wash and repour if desired.
