What a beautiful candle! Think of the options, this is your opportunity to get creative, safely. Customers have been dealing with this problem for years, and there have been many innovations but still always the risk that flowers or coffee beans could float into the flame.
In this option, you can tailor it to suit yourself. Gel wax could be very impressive as the outer section, or of course both vessels. Simpler, the way we have done it with soy simply poured over the lot.
Put the wax on to melt - see instructions
Collect your jars - in this project we have used 2 clear jars:
The wick used in the correct size for the smaller, inner glass.
Collect your embeds - dried flowers, coffee beans, shells, glass beads. Even though some of these may not be flammable, it is a very good way to hold them tight against the edges of the candle. Dried flowers etc. would be better choice than fresh.
Be sure not to pack too much matter in the outer glass - there needs to be enough space for the wax to flow freely through it.
Arrange your embeds between the 2 glasses.
**Do not pack above the top of the inner glass - there should be no possibility of flammables floating towards the flame.
Pour the candle using soy, paraffin or gel wax and wick accordingly, appropriate for the wax you've chosen and the inside diameter of the inner glass.
The wax should cover the inside glass, hiding it to make a 'perfect' candle.
TEST: The outer shell of wax has melted here when we tested an extreme 12 hour burn. Normal length burns should leave the outer layer of wax white, with a soft glow through.
Also the material used in the 'red' candle was not good quality and the colour has moved into the wax.
