Chop 32 ounces of White Melt and Pour Soap Base into small uniform pieces. Place all the soap into a large heat-safe bowl. Place the bowl into the microwave and melt the soap using 30 second bursts. Between each burst, stir the soap to help it melt evenly and prevent overheating. Continue heating and stirring until the base is completely melted.
Add all of the dispersed rose clay and rosehip powder to the melted soap and stir to fully mix in the powders.
Add 0.3 oz. of lavender 40/42 essential oil, 0.3 oz. of lemongrass essential oil, and 2 Tbsp. of poppy seeds. Stir to fully mix in the ingredients.
Once the soap is poured into the mold, the mold shouldn’t be moved or the seal could break. Move the mold to where you’d like it to fully cool and harden. Check the temperature of the soap. If it’s above 130° F, the poppy seeds may fall to the bottom of the mold. Once the soap is about 125° F, carefully pour into the mold. Use one hand to steady the mold as you pour to prevent it from falling over.
Spritz the top with 99% isopropyl alcohol to get rid of bubbles. Allow the soap to fully cool and harden for at least 4 hours or up to overnight.
Once the soap is completely cool and hard, remove from the mold. Use a crinkle cutter to cut the soap into bars. Cut them as thin or as thick as you’d like. You can use a non-serrated knife if you prefer a smooth look. Wrap the soap in plastic wrap to prevent glycerin dew and enjoy.
