Trim wick to 1/4″ before lighting. Keep the candle free of any foreign materials including matches and wick trimmings. Only burn the candle on a level, fire-resistant surface. Do not burn the candle for more than four hours at a time. Stop use when only 1/4″ of wax remains.
Bonus: when the wax is almost completely exhausted, you can pour a bit of boiling water into the container and on the labels to remove the adhesive and remaining wax, wiping out with a paper towel or old newspaper. Then, you will have a great jar to store seeds, herbs, or other dry goods for many years to come. Because they are glass jars, they will only ship in a box (not our typical padded mailers), and shipping will be precisely calculated for the weight of your complete order and distance to your shipping address.
CAUTION: Burn only on a stable heat resistant surface. Keep from drafts. Do not burn candle when wax is less than 1/2 inch from bottom. Do not touch or move candle while burning, or if wax is hot. Never leave candle burning unattended. Keep out of reach of pets and children.
