Kerax 4105 Blended Container Wax
Candle Shack Blended Container Wax is a Palm blend designed specifically for use in Glass & Container candles. Manufactured by Kerax, a leading UK wax refiner, it contains both Palm wax and Paraffin wax, combining the scent throw of a paraffin wax with the creamy appearance of palm. It has a low melting point and sets up very quickly, making it an ideal wax for beginners.
This wax has excellent cold and hot scent throw and is very easy to work with. The wax contracts, so this wax usually requires a second pour, but the results are worth it, especially in terms of scent throw. Pour this wax at 50-60C and second pour at ~65-70C for best results. Blended container wax is delivered as wax beads. As with most paraffin blends, the wick should be kept trimmed on finished candles to prevent smoking.
This wax is very dense and requires a powerful wick to establish a full melt pool. We would recommend Wedo V wicks with this wax as follows:
80mm Melt Pool: V14 - CL16 - Stabilo 16 (may smoke if wick not carefully maintained)
75mm Melt Pool: V14 - CL14 - Stabilo 14
70mm Melt Pool: V12 - CL12 - Stabilo 12
65mm Melt Pool: V10 - CL10 - Stabilo 10
60mm Melt Pool: V8 - CL8 - Stabilo 8
55mm Melt Pool: V7 - CL6 - Stabilo 7
As ever, this is just a guide, as fragrance and dye can impact wick selection.
SLAB TESTING (HOW TO CHOOSE A WICK...)
The below process is a very quick way of finding suitable wicks for your candles. We recommend you conduct a slab test for every different blend of wax and oil that you intent to use, before making any candles :)
1. Mix the wax and your chosen oil at the required loading (typically 7-10% fragrance)
2. Pour the mixture into a large baking tray and allow to cool fully
3. Remelt the surface so that it is flat and allow to settle for at least 24 hours
4. Poke holes at ~10cm intervals using a skewer, screwdriver or similar
5. Insert various wicks that you think may be suitable (we recommend trying as many as possible)
6. Trim and light wicks in a draft free room
7. Allow to burn for 3-4 hours, observing for clubbing, excessive smoke or flame height and wick posture
8. Extinguish wicks, allow to cool and record diameter of melt pools for each wick, along with any observations on posture/clubbing/flame height
9. Remove wicks and any residue from wax, then remelt surface and repeat steps 4-8 as required (you may need pliers to remove the wicks)
10. Once complete, the wax can be used to make candles of various sizes and conduct confirmatory container tests.
If done correctly, a slab test will provide you with a long list of wick options that will allow you to wick almost any size of container.
CONTAINER SPECIFIC BURN TESTING
Slab testing will help you to identify candidate wicks for your candles, but you will still need to conduct tests in the actual container you intend on using. We call this container-specific burn testing.
We recommend that container specific burn testing be conducted in accordance with the following standards before putting candles up for sale...
EN 15493:2007 – 'Candles – specification for fire safety'
- EN 15426:2007 – 'Candles – Specification for sooting behaviour'
You may also wish to apply safety labels as outlined in the following standard...
- EN 15494:2007 – 'Candles – product safety labels'
These standards are available for purchase from The British Standards Institute and other bodies within Europe.
