1) Calculate the amount of wax needed to make the candle.
If you’re using your mold for the first time, you need to measure how much wax it will take: place the mold on the scale, turn it on, and fill the mold with water. Multiply the water weight (g) by the wax density (≈0.9 g/mL for many waxes). Then add 3–10% to account for residue in the pouring pot. For best accuracy, weigh the finished candle and save the exact grams for next batches.
2) Place the melting pitcher on the scale and tare it, then add the required amount of wax.
