Non-combustible additive must not enter the burn pool
Mica, metallic powders, and similar pigments do not combust. In the melt pool they wick into the flame, spark, and discolour it. Use them only as a surface dusting applied after the top has set, never mixed into the wax.
What this means for your recipe
When this rule fires the recipe is Blocked. The numeric score is hidden — a single Danger collapses the band on its own. Resolve the underlying condition before pouring or selling. The same rule fires every time the underlying condition is true, so the way to lift the score is to change the recipe, not the rule.
