Ceramic glazes can contain lead and cadmium, which leach into food during long cooking times (4-10 hours) at low temperatures. California Prop 65 has flagged multiple slow cooker brands for lead in ceramic glaze. Acidic recipes (tomato-based stews, chili) accelerate leaching.","synthesis":{"derived_risk_level":"moderate_to_high","synthesis_confidence":0.744,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":0.85,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","compounds_resolved":2,"compounds_total":2,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
