Is Boneblack Pescatarian?

Avoid

No. Boneblack is bone charcoal made by roasting bones. It's sometimes used in refining cane sugar.

Boneblack and the Pescatarian Diet

Boneblack, also known as bone char, is a black, porous, and granular material produced by heating animal bones in an oxygen-limited environment. This process removes volatile substances and leaves behind a carbon-rich material that is often used for filtration and decolorization in various industries, most notably in sugar refining to produce white sugar. Due to its origin, boneblack is not considered suitable for vegetarians or vegans.
