OK, I should probably know these things, but I don’t. What is DB and what is soap dough?
DB in the Fragrance Oil context is Dragon's Blood by several folks here.
Soap Dough is saponified CP soap that has been kept moist so that it doesn't harden until after exposed to air. The purpose is so that designs can be in as if one is working with modeling clay. Once the sculpting is done, by exposing the soap to the open air, the evaporation of water begins and the soap will harden. We did an SMF Soap Challenge on using soap dough.
