La Tee Da effusion lamps use a small, intermittent flame to keep the oil within them at a warm, even temperature. The lamps themselves usually feature an egg shape made of highly decorated glass with an openwork metal cap that allows fragrance to waft out. The oil sits in the body of the lamp. Since the oil temperature doesn’t rise much, it burns away at a slow rate, which helps it to last for several weeks. However, the brand-name oil is still rather expensive. By making your own La Tee Da oils, you can customise your scents and remain within your budget.
Pour about 1½ cups of isopropyl alcohol into a glass jar. The alcohol should be free of colouring and other ingredients. The purer the alcohol, the faster it will emulsify the oils.
Add a teaspoon of a single oil to your alcohol. If you're using more than one oil, drip about 40 drops each of two oils, 15 drops each of three oils and 10 to 12 drops each of four oils. Using more than four oils may create an unpleasant, muddled scent.
Cap the jar tightly and shake vigorously for about 10 seconds. Pour an appropriate amount of your oil into your lamp or store the oil in a cool, dark and dry place until you need it. It should keep for about a month.
Adjust your oil scents to your needs. For instance, most mints, pine and rosemary help focus the mind and give you energy. Eucalyptus and citrus chase away illness, while lavender and chamomile are calming. Make sure you essential oils are true oils and not synthetic. Synthetic oils may smell like burning plastic when warmed. Most sites and shops that sell oil lamp supplies also sell true essential oils.
