What are your candles made of?

All K. Hall Studio products are made using the highest quality ingredients available. We take pride in the fact that our wax is made from soy and vegetables grown by American farmers.

What can I do the first time I burn a candle to help it last longer?

The first time that you burn a candle, it should burn until the wax pool melts all of the way to the edges. Depending on the size of the candle, this could take 2-3 hours. The wax has “memory” and doing this will help to the candle to burn more evenly, longer and the wick will not funnel down in the wax.

What helps to prolong the life of a candle?

Trim the wick ¼”before you light the candle each burning.

Can I keep the candle vessel for decoration after the candle has completed burning?

Yes! Many K. Hall Studio customers like to use the candle vessel as a vase, to hold jewelry or a decorative accessory in the home after the candle has completed burning. To remove the excess wax  in the vessel, simply place the candle vessel in the freezer. After several hours, the wax will harden and can gently be removed with a butter knife or blunt object.


How long will scent diffusers last?

We recommend to add diffuser oil when the bottle becomes half empty or every six months.

Will the diffuser oil harm finished surfaces?

The diffuser oil should never be poured into a diffuser on a finished surface. The oil can cause damage to surfaces. The oil can take paint/finish off of surfaces and discolor fabrics. Use extreme care when pouring the oil into the diffuser bottle. Many customers pour the oil into the bottle in a sink and then wipe any drips of oil carefully from the bottle prior to placing the diffuser in the desired location in the home.

How often should I flip the diffuser reeds?

We recommend flipping the reeds once per week to deliver continuous fragrance. When flipping the reeds, make sure to carefully flip them without dripping the diffuser oil. It is best to flip the reeds over a sink or a towel.

Is diffuser oil safe to ingest?

NO!  Fragrance diffuser oil should be kept away from children and pets and it is not safe to ingest. Immediately contact your physician or poison control if accidental ingestion occurs.
