You’ve got your mould or your container and you’re ready to make some candles but how much wax do you need?
It’s dead easy to work out.
- Fill the container or mould with water (if it’s a mould, cover the hole with your finger) to the proper level
- Tip the water into a measuring jug, round up to the nearest 10ml or so
- Deduct 20%
- That’s the number of grams of wax to use
For example if your container takes 250ml of water, you would use 200g of wax (250-50).
This is because 1ml of water weighs exactly 1 gram (for the nerds amongst you this is because a kilogram is defined as the weight of 1 litre of water). So 250ml of water weighs 250g. However, wax is slightly less dense than water so you need to deduct 20% or so to get the right weight in wax.
