FDA vs LFGB Extractives for Chocolate and Baking RTV
21 CFR 177.2600 and LFGB/BfR XV are extractives tests, not badges. Chocolate fat and oven heat fail different limits. Test the colored, post-cured RTV

Mold Release on the Master, Not Inside the RTV Cavity
On RTV work, release belongs on the master, not in the cavity. Semi-permanent films sit on steel parts tools. Never solvent-spray a culinary pour face.

Dry Ice vs Ultrasonic Cleaning: Not for Soft RTV Skins
Dry ice and ultrasonic clean metal parts tools. Do not blast a soft RTV skin. Wash the cavity; recast when residue is in the rubber, not on it.
