Night Star melt and pour soap has soft yellow stars floating in crystal clear soap against a deep blue, glittery night sky. It was inspired by a favorite bedtime story, and after a couple of tries, this version finally turned out the way I pictured it. The big secret: keep the clear part of the soap completely plain, and don’t pour it too hot.

Fragrance Amount
Add fragrance only to the stars and the blue background, never to the clear layer. Use up to 5 ml of fragrance oil per 16 oz (1 lb) of soap base. You can always use less if you like a lighter scent, but don’t go over 5 ml per 16 oz.
How to Make Night Star Melt and Pour Soap
1. Color the Shea Butter for the Stars
Melt the shea butter base. Mine was 180°F, so I mixed the micas with alcohol while it cooled. Stir in Yellow Lemon. It’s a soft, pretty yellow, not neon. Add fragrance once the soap is around 140°F.
2. Pour a Thin Yellow Sheet
Pour just enough yellow soap into a rectangle mold to cover the bottom. You want a thin sheet. Let it cool and set.
3. Cut the Stars
Unmold the yellow sheet onto a silicone mat and cut out stars with fondant cutters. Using three sizes looks more like a real night sky. Lay them in the empty oval mold to see how many you need. Leave room for the blue to show through.
4. Pour a Thin Clear Layer
Melt the clear base and stir out any skin. Don’t add any fragrance, color or glitter to the clear part. Pour a thin layer into the bottom of each oval cavity.
5. Place the Stars
Spray the stars with alcohol and place them in the clear soap. Don’t overthink it. They’ll slide around wherever they want anyway. Add a thin top layer of clear soap to lock them in and spray with alcohol.
6. Pour the Blue Night Sky
Mix Ice Blue into the remaining clear soap with a touch of bio glitter and your fragrance. If it starts to set, warm it for about five seconds. Pour at about 133°F, never above 135°F, so you don’t melt the stars. Spray with alcohol and let it set.
7. Unmold and Clean Up
Pop the soaps out and trim off any little lips around the back.
Tips & What I Learned
- Keep the clear layer plain. Fragrance, glitter and color can cloud it. Add them to the embeds and background only.
- Pour at 135°F or a little less. Hotter soap can melt the stars.
- Use different star sizes. Big and little stars look more natural.
- Leave space between the stars. The blue sky should show through.
Troubleshooting
My clear soap is cloudy.
Fragrance or glitter was added to the clear layer. Keep it plain.
The stars melted or blurred.
The blue layer was too hot. Let it cool to about 135°F or below.
The stars moved when I poured.
Lock them in with a thin layer of clear soap before the background pour.
