## Tool capabilities

| Property | Value |
| --- | --- |
| Tool ID | `candle-wax-calculator` |
| Category | calculators |
| Implementation | Registered implementation. Registration alone is not a production-quality guarantee. |
| Browser execution | Automatic updates after valid input or file selection. |
| Browser processing | Browser; see tool notes for network behavior. |
| HTTP API | Not callable through HTTP. |
| Browser-agent interface | run_current_tool |

### Implementation notes

Calculate wax and fragrance from the container fill and your blend density, or from a measured combined fill mass. Use the fragrance limit supplied for your actual materials. Changing units keeps the entered numbers. Calculations run on your device.

### Inputs and settings

No free-text input is required. Use the file inputs and/or settings below.

| Setting | Meaning | Control type | Default | Constraints |
| --- | --- | --- | --- | --- |
| `mode` | Known fill measurement | select | "Container volume" | Allowed: Container volume, Measured mixed fill mass |
| `fillVolume` | Volume to the intended fill line | number | 200 | min=0 max=1000000000 step=any |
| `volumeUnit` | Fill volume unit | select | "mL" | Allowed: mL, L, US fl oz, Imp fl oz |
| `blendDensity` | Measured wax-and-fragrance blend density (g/mL) | number | 0.9 | min=1e-06 max=100 step=any |
| `fillMass` | Measured combined fill mass per container | number | 180 | min=0 max=1000000000 step=any |
| `massUnit` | Fill mass unit | select | "g" | Allowed: g, kg, oz, lb |
| `containers` | Containers | number | 10 | min=1 max=10000 step=1 |
| `fragranceLoad` | Fragrance as a percentage of wax mass | number | 8 | min=0 max=100 step=any |
| `extra` | Extra material allowance (%) | number | 5 | min=0 max=100 step=any |
| `outputUnit` | Output mass unit | select | "g" | Allowed: g, kg, oz, lb |

### Browser-agent workflow

1. Open the human page in a browser that supports WebMCP.
2. Discover the interface exposed by that page; use its actual schema.
3. Select files on the page first when the tool requires files.
4. Call `run_current_tool` with valid input and settings.
5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.

Calls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.

### Planning specification

Up to 10,000 containers. Arithmetic accepts 0–100% wax-relative loading; that is a calculation bound, not approval for a material formula. Extra allowance applies once to the batch.

This describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.

### How to use Candle wax calculator

1. Enter your measurements, rates or supplied recipe.
2. Review the quantities, rounding and plan details.
3. Download the result and verify it against your actual materials or a sample.

## Start with the intended fill

Volume mode multiplies the fill volume by the measured density of the combined wax-and-fragrance blend. The example density is editable and is not a universal wax value. If you have a tested combined fill weight, use Measured mixed fill mass instead.

### Keep the fragrance denominator clear

An 8% fragrance load means fragrance is 8% of the wax mass. It is not 8% of the finished mixture. A 1,890 g combined batch at that load contains 1,750 g wax and 140 g fragrance. Use the permitted loading for your specific materials and verify the actual fill.

### Save the plan

Download the result as CSV, plus a text or JSON report with formulas, values and assumptions. Everything is calculated on your device. Changing units keeps the entered numbers, so check the selected units before using the plan.
