- Impact: Taller candles contain more wax, which generally results in longer burn times.
Candle Diameter (cm):
- Description: The width of your candle at its widest point.
- Impact: Wider candles require larger wicks to maintain a proper flame, influencing the burn rate.
Wax Type:
- Options: Soy Wax, Paraffin Wax, Beeswax
- Description: Different waxes have unique properties affecting burn performance.
- Impact: Each wax type has a specific burn rate and density, directly influencing burn time.
Wick Type:
- Options: Small Wick, Medium Wick, Large Wick, Extra-Large Wick
- Description: The size of the wick determines how efficiently the candle burns.
- Impact: Larger wicks increase the burn rate, leading to shorter burn times, while smaller wicks decrease the burn rate, resulting in longer burn times.
Note: By default, the calculator automatically suggests a wick type based on your candle's diameter. However, you have the flexibility to manually adjust the wick type if desired by checking the "Manually Select Wick Type" option.

2. Calculation Process

Our calculator uses a systematic approach to determine the Estimated Burn Time. Here's a step-by-step breakdown of how it works:

A. Calculating the Volume of the Candle

First, the calculator computes the Volume of your candle using the formula for the volume of a cylinder:

Volume (V) = π × (Diameter (D)/2)² × Height (H)

Example: For a candle with a diameter of 5 cm and a height of 20 cm:

V = π × (5/2)² × 20 ≈ 392.70 cm³

B. Determining the Total Mass of the Wax

Next, the calculator calculates the Total Mass of the candle's wax using the formula:

Total Mass (M) = Volume (V) × Wax Density (ρ)

Wax Densities:
- Soy Wax: 0.9 g/cm³
- Paraffin Wax: 0.7 g/cm³
- Beeswax: 0.96 g/cm³
Example: Using the previous volume and Soy Wax:

M = 392.70 cm³ × 0.9 g/cm³ = 353.43 grams

C. Calculating the Effective Burn Rate

The Effective Burn Rate is determined by multiplying the Wax Burn Rate by the Wick Burn Factor:

Effective Burn Rate (E) = Wax Burn Rate (R) × Wick Burn Factor (F)

Wax Burn Rates (grams per hour):
- Soy Wax: 8 g/h
- Paraffin Wax: 10 g/h
- Beeswax: 9 g/h
Wick Burn Factors:
- Small Wick: 0.7
- Medium Wick: 1.0
- Large Wick: 1.2
- Extra-Large Wick: 1.4
Example: For Soy Wax with a Medium Wick:

E = 8 g/h × 1.0 = 8 g/h

D. Estimating the Burn Time

Finally, the calculator estimates the Burn Time using the formula:

Burn Time (T) = Total Mass (M) / Effective Burn Rate (E)

Example:

T = 353.43 grams / 8 g/h ≈ 44.18 hours

3. Factors Influencing Burn Time

Several key factors determine the accuracy and reliability of the burn time estimation:

A. Wax Density (ρ)

Definition: The mass per unit volume of the wax.
Impact: Higher density waxes result in a greater mass for the same volume, leading to longer burn times.

B. Wax Burn Rate (R)

Definition: The rate at which a specific wax type burns, measured in grams per hour.
Impact: A higher burn rate means the candle consumes wax faster, reducing burn time.

C. Wick Burn Factor (F)

Definition: A multiplier that adjusts the burn rate based on wick size.
Impact:
- Larger Wicks: Higher burn factors increase the effective burn rate, leading to shorter burn times.
- Smaller Wicks: Lower burn factors decrease the effective burn rate, resulting in longer burn times.

D. Candle Dimensions (Height and Diameter)

Height: Taller candles have more wax, contributing to longer burn times.
Diameter: Wider candles require larger wicks to maintain an optimal flame, affecting the burn rate.

4. Manual Wick Selection

While the calculator provides an automatic suggestion for the wick type based on the candle's diameter, you have the option to manually adjust the wick type if you have specific preferences or requirements. This flexibility ensures that you can tailor the burn time to meet unique design specifications or personal preferences.

5. Tips for Accurate Results

To ensure the most accurate burn time estimates, consider the following tips:

Accurate Measurements:
- Use precise tools to measure candle height and diameter.
- Ensure measurements are taken at the widest point for diameter.
Consistent Wax Quality:
- Use high-quality waxes with consistent densities.
- Store wax properly to maintain its properties.
Proper Wick Selection:
- Choose a wick size appropriate for your candle's dimensions and wax type.
- Avoid under or over-sizing the wick, as it can lead to incomplete burning or excessive soot.
Controlled Testing Environment:
- Test burn your candles in a stable environment to account for external factors like airflow and temperature.
Regular Calibration:
- Update your calculator parameters based on real-world burn tests to enhance precision.

6. Understanding the Results

The Estimated Burn Time provided by the calculator serves as a guideline based on the input parameters. Actual burn times may vary due to factors such as environmental conditions, wick placement, and wax purity. Always perform real-world tests to validate the calculator's estimates and make necessary adjustments for optimal performance.

We hope this guide enhances your understanding of how the Candle Burn Time Calculator works and the factors that influence burn time. By leveraging this tool, you can create high-quality candles with predictable and reliable burn performances, ensuring satisfaction for both you and your customers.

Precise Candle Burn Time Calculator (Based on Actual Burn Data)

The Precise Candle Burn Time Calculator provides an accurate estimate of your candle's total burn time using real burn data. Input the candle’s original weight, post-burn weight, and hours burnt to calculate how long your candle will last based on its actual usage. Ideal for getting precise results!

How This Calculator Works:

This calculator gives a more precise estimate of total burn time based on actual data from a candle that has already been burned for some time. Instead of relying on approximations, it uses real-world measurements to calculate the exact burn rate and remaining burn time.

The calculator requires the following inputs:

Original Weight of the Candle (grams): This is the total weight of the candle before it was lit. The original weight includes both the wax and the wick, though the wick is a negligible factor in most cases.
Post-Burn Weight of the Candle (grams): After burning the candle for a certain period of time, the remaining weight is measured. This allows the calculator to determine how much wax has been consumed during the burn.
Hours Burnt: This is the amount of time the candle has been burning, which is used to calculate the rate at which the wax is being consumed.

Calculation Breakdown:

Amount of Wax Consumed: The calculator subtracts the post-burn weight from the original weight to find out how much wax was consumed during the burn session:

Wax Consumed = Original Weight - Post-burn Weight
Hourly Burn Rate: It divides the amount of wax consumed by the number of hours the candle has been burning. This gives the burn rate, which is how much wax the candle uses per hour:

Hourly Burn Rate = Wax Consumed / Hours Burnt
Approximate Total Burn Time: Finally, the calculator divides the original weight of the candle by the hourly burn rate to estimate the total number of hours the candle will burn:

Total Burn Time = Original Weight / Hourly Burn Rate

In Summary:

This method provides a highly accurate estimate of burn time because it is based on actual burn data from your candle. It accounts for specific environmental conditions, wax consumption rate, and how your particular candle burns.

Key Differences Between the Two Calculators:
