It is exactly what it sounds like, and the devs refuse to apologize. Its Toxic Sludge trait is no joke.
Coats the edge in foul sludge that keeps burning.
How the waterline works. The game counts Poopite's share of the total crucible: under 10% the trait is INACTIVE; 10–30% it scales linearly (SCALING); 30–35% is OPTIMAL (full 6%); past 35% it is OVERCAP — the trait stays maxed but the extra ores are wasted multiplier.
Exact top-up formula. Adding Δ ores also grows the total N, so the real formula is Δ₁₀ = ceil((N − 10n) / 9) for the 10% line and Δ₃₀ = ceil((3N − 10n) / 7) for the 30% sweet spot — never the naive "fill to 30%".
Worked example. Say your 50-ore crucible already holds 8 Poopite (16%, SCALING at 3.9%). To max out you need +10 more — landing at 18/60 = exactly 30%. And a tiny 30-ore forge holding 2 Poopite needs +2 to wake the trait (4/32 = 12.5%).

Poopite carries a 1.2x crucible multiplier — C tier, rare rarity — sourced from Stonewake's Cross. A crucible loaded entirely with Poopite forges at exactly 1.2x.
Toxic Sludge caps at 30% of the crucible load: ceil(0.3 × N) ores — 15 Poopite in a 50-ore forge. At 10% it activates at 3%, reaching the full 6% at 30%.
Mushroom Cluster (Stonewake's Cross) at 8.5%; Scrap Heap (Stonewake's Cross) at 6.7%.
Poopite is early-game filler: 1.2x multiplier is low, so swap it out once better ores from Stonewake's Cross or beyond are unlocked.
