1. If using tea in place of water, the day before you plan to make soap, brew the tea. Measure slightly more water than needed in your recipe, and heat to a boil. Remove the water from heat and place tea bags in the water. I used 4 regular size tea bags, and let steep for about 1 hour. I wanted dark tea for the color. Remove tea bags, and leave the tea at room temperature, or place in the fridge to chill. From my 2 batches, chilled tea resulted in darker finished product.

2. Prepare your soap molds.

3. Measure the tea by weight, pouring into a glass, ceramic, or steel vessel. If you do not have enough tea, add distilled water until you reach the desired weight of liquid. Ensure that your tea is room temperature or cooler (see note below).

4. Place the container with the tea in a well ventilated area where it will not be disturbed. I use my sink with the nearby window open. Wearing safety glasses and gloves, carefully measure the lye. Slowly pour the lye into the tea and stir gently with a wooden spoon or silicone spatula to dissolve.

5. Measure the oils into a large glass, ceramic, or steel container. Heat slowly until the solid oils are fully liquefied. I use the ceramic pot from my crock pot, and heat either in the crock pot on "warm" or "low", or I microwave the pot with oils.

6. Carefully pour the lye solution into the oil solution. Using an immersion blender, blend the solution until achieving trace, typically 3-5 minutes. Trace means that all of the lye is fully mixed in with the oils, and is achieved when the solution has a cake batter to pudding-like consistency; when the blender is lifted out of the soap and drizzles on the surface, traces of the drizzles stay on the surface.

7. Pour the soap into molds and place somewhere that the molds can be left undisturbed for 24 hours. I have used a closet and my microwave. At this point the lye is still present in the soap, so use care not to touch it.

8. After 24 hours, you may test the soap to determine if it has fully saponified. I use the "tongue test" - touch the tip of your tongue to the soap. If you feel a zap - like touching your tongue to a 9 volt battery - the saponification process is not yet complete, and you should leave the soap for several more hours.

9. Remove the soap from molds and cut to your desired size. The soap is still somewhat pliable at this point, so be careful not to make undesired marks with your tools or fingers. You can also use this time to smooth edges on your soap.

10. Place the soap bars to dry. I line a large shallow box with waxed paper and stand the bars up on end with space between each bar. Allow the soap to dry at least 6-8 weeks before using. Longer dry times should result in harder soap bars that last longer.
