When making candles with paraffin wax, you may have encountered contraction of the wax, causing holes / air bubbles, uneven surface, and possibly discoloration.
Adding Multi-Supplement helps strengthening the wax and prevents hyper-contraction and discoloration.
From above picture, left one is with 2% supplement, and the right one is without the supplement.
Per 1kg of wax, add about 20g of the supplement.
Multi-Supplement can only be used with paraffin wax, which has 60C or higher melting point.
