If in doubt, melt a bit more than you expect to need.Ok so I need the calculator during my many blonde moments but this formula works for me every time. Cracklewood Wood Wick Candles, with a unique patented chimney wood wick Instead they use mostly the trim and crystal bearing leaves. The True Terpenes mixing calculator is easy, and dare we say, fun to use! You’ve got your mould or your container and you’re ready to make some candles but how much wax do you need?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 if I have 230g of wax how many mls of scent do I need in mls for the strongest scent please sorry.I wanted to make a candle in a holder I have, the volume is .5 cubic foot, it is a cylinder, when I do the math it works out to 10000 millilitres of wax needed, it is 7 inch radius and 8 inches high, that certainly would cost a fortune to buy that much waxHi Scott, that doesn’t sound right at all! 1 cubic meter is equal to 1000000 milliliters, or 1000000 grams. And each is hard to find.
