How do I calculate the amount of wax needed for my jar?

You can use the `calculate_formulation` tool. Provide the container volume, the unit (ml or oz), the wax type, and your desired fragrance load percentage.

Can this tool help me choose a wick?

Yes. By using `analyze_wick_performance` with your container diameter and chosen wick series, the engine predicts the optimal wick size and expected burn time.

How does shrinkage affect my candle?

Different waxes contract at different rates. Use `predict_shrinkage` to estimate the percentage of volume loss and the structural risk, especially for freestanding pillar candles.

This MCP server provides a deterministic engine for candle makers to calculate exact ingredient weights and burn characteristics. Use calculate_formulation to determine the precise mass of wax and fragrance oil needed for any container volume. Use analyze_wick_performance to predict melt pool depth and burn hours based on container diameter. Additionally, predict_shrinkage helps assess structural risks for pillar candles and container candles by estimating wax contraction during cooling.
