When using wax resist on my work I find it easier to see the design if I add a one or two coloured candles to the mix. The mix I use is 2 parts candles to 1 part paraffin (kerosene), The mixture is heated to a liquid and brushed on to the work. Take care not to overheat the mixture as it is highly flammable.
Once the wax is applied the piece is washed with a solution of Cobalt Chloride and fired to 1260oC giving the result seen here.
