We have kept all the remnants and I need advise how to make up new candles. For instance where do you get new wicks? How do you get the wick to be in the centre of the newly made candle. How do you make a new candle? Is it possible to make your own candles from scratch?
Does anybody know about such things? Cause I don't.
I've made quite a few candles from raw materials. There are a variety of people willing to sell you the stuff:

For a new candle, you melt wax beads and add about 10% stearin (to make the wax harder, and I think it helps it contract when cooling), and also any dye or scent you might want. You melt all this in a small saucepan inside a bigger one full of water. This keeps the temeprature at or below 100C, so avoiding reaching the flash-point of the wax, which would be dangerous!!
You have a plastic (other materials may do, but I've never tried) mould through which you thread a wick, tied round a pencil across one end of the mould, and threaded through the small hole at the other end, then sealed in (I use blu-tak, but there's some putty you can get as well I think). The end of the wick that comes out of the mould has to be taped onto the outside of it, as it must be taut within the mould. You should also wipe the inside of the mould with veg oil, so the candle doesn't stick.
Once all this is set up, you pour the wax/stearin/dye mixture into the mould, and then place the whole thing into cold water. Remember it will try and float, so you either need the water level well below the edge of the mould, or else you weight it to keep it down. Don't get any water into the wax! Sometimes the wax contracts a lot as it cools, and you get a depression in the mould - if you keep some leftover wax melted in the pan, you can fill this in after 30-60 minutes.
Once it's cooled (several hours, best left overnight), you untape/cut the wick from the mould/pencil, and out comes the candle!
Now, for recycling old candles, the procedure is basically the same, and if you use dyes appropriately, you'd never know it wasn't a new one. One important difference is that you don't need to add any more stearin, as the original candle should have a suitable amount in it anyway.
If you fancy getting adventurous, here are some of the things I've tried:
- different moulds - short & fat, tall & skinny, hexagonal, spherical. It's worth figuring out which make the best burning candles, and give off the most light, as well as which look nicest.
- different wicks - the width of the wick should be adjusted to match the mould, but there is a wide range you can play with. Thick wick = big flame = bigger pool of melted wax
- make a small clear candle in the middle of a long wick, then suspend it inside a larger mould into which you add dyed wax - you get a nice coloured light coming out through the whole candle.
- make a clear candle, and drip coloured wax in streaks over it.
- try putting lumps of coloured solid wax into a clear candle, or pouring two wax colours together into the mould, somehow stopping them from mixing too much.
As you can see, there's quite a lot of variables to play with, some affecting burn time and brightness, and others just affecting aesthetics. Mind you, if you can make cool looking candles, maybe you could sell them - could be a viable post-peak income!
Oh, and it's actually quite good fun!
