Frequently Asked Questions

We hope the information below will help you to better enjoy your soy candles safely and will answer some questions you might have on our products.

Why are soy candles more expensive than paraffin?
In other words, why can I buy a candle for $1.99 at the discount store? ;) Paraffin candles are cheaper to make and materials are less expensive to use. They can also give off carcinogens, can be created from cheap materials that are not recyclable and can release toxic emissions.

Soy candles are eco-friendly and while the materials used to create them are more expensive, they do not give off toxic fumes and they burn much longer than paraffin candles. Whenever possible, we use recyclable materials and jars. We even try to recycle our packing materials and shipping boxes for re-use.

What are 'tunnels' and how can I prevent them?
'Tunneling' is when a candle burns down the middle of a jar, leaving large amounts of wax stuck to the sides. Many candles tunnel due to incorrect wick size or type. GSC candles are wicked to burn clear and prevent tunneling.

However, tunneling can also be caused by failure to keep your candles lit long enough before you extinguish it. Each time you burn a candle, try to burn it until the liquid wax reaches the edge of the container. If you must extinguish it early, try to burn it a little longer next time. This should prevent your candle from tunneling.

Do I really have to trim the wick?
In a word, yes. You should trim the wick to 1/4" before you light or relight your candle. Problems can occur if the wick is not trimmed back.

Soy candles do not produce the toxic soot that paraffin candles do, but when not properly trimmed, the wicks of all candles can 'mushroom' at the top, causing excessive flickering or smoke. Keeping your wick trimmed reduces this to minimum and also makes your candles safer to burn.

Trimming also keeps your wick from curling back into the wax - a common problem with non-metal cored wicks. Because our wicks contain no lead, zinc, or metal of any kind, they are very easily trimmed by just breaking off the top of the wick (the curled part) before lighting.

What is 'frosting'?
Frosting is when the soy wax forms tiny, white, frosted-looking crystals on the top of the wax or sides of the jar. Most people don't mind frosting and like the effect. In fact, many customers have said they look for frosting as a sign that the candle is indeed made with soy wax.

Some soy candles manufacturers add paraffin wax (called a parasoy blend) to eliminate frosting. We are committed to providing you with the best candles possible and therefore do NOT add paraffin to our wax. We have done extensive testing over the years with our dyes, fragrances and pour temperatures to keep frosting to a minimum but some frosting is to be expected with all pure soy candles.

Are Greenhouse Soy Company's candles natural?
Most candles, even 100% soy candles, contain ingredients that are synthetic, such as dyes and fragrances. Synthetic does NOT mean unsafe. Many 'natural' ingredients can be harmful at times and many synthetic ingredients are perfectly safe and eco-friendly.

We believe two of the most important things to consider when purchasing a candle (other than safety) are:

1) Possibly toxicity when burned, which is determined by the type of wax used

2) Its impact on the environment (eco-friendliness)

Our product decisions are made accordingly. Our soy wax is made using 100% natural soybeans and contains no petroleum. Our wicks are metal-free and made of natural ingredients such as cotton and paper. Even our dyes are eco-friendly and contain no hazardous solvents. We use only the highest-quality synthetic fragrances, which often contain essential oils.
