Place an inch of water into the bottom pan of your double boiler and turn on medium heat.
Place all ingredients (except your essential oils - if you're adding them) into the top pan or glass of your double boiler. Allow melt for a few minutes. Be sure not to get any water in your mixture.
When all ingredients are melted, stir well and remove from heat. Keep your top pan or glass on top of your double boiler. Sift matcha into your mixture. Mix for 2-3 minutes until you break up all of the tiny matcha clumps. Note: sifting your matcha is an important step to avoid having large clumps of matcha in your mixture.
Use a glass dropper or pipette to quickly fill your containers. Fill each lip balm tube/container to the top. This part needs to be done quickly to avoid your mixture solidifying inside of your glass dropper or pipette. If your mixture solidifies in your double boiler, simply place it back on the heat and melt for a few minutes.
Let the containers cool off for a few hours. Place the tops back on.
