Step 1

In a large mixing bowl, combine 7.70 oz Baking Soda, 5.72 oz Bubble Cake Hardener, and 4.62 oz SLSa. Whisk gently to combine, breaking up any clumps.

Step 2

Add 1.32 oz Bubble Up and gently fold in with a spatula.

Step 3

Add 2.42 oz Glycerin and gently fold in with a spatula.

Step 4

If desired, add up to 1% (0.22 oz) Fragrance Oil and fold in.

Gently knead the mixture with gloved hands until it forms a dough.

Begin filling the mold by breaking off a piece of dough and packing it in each cavity. If the dough gets too dry and starts crumbling, add a little more glycerin to hold it together.

Gently remove hardened bars from the mold and package as desired.
