Andrew made a solar wax melter (from the instructions below) and gave it to me for my birthday last week. Very kind. It it a good design and has been melting wax since the weekend to great effect. The old comb from the brood box (which has gone very dark brown) does not seem to melt very well – but Andrew said it is better if you put it in the oven. If anyone has any ideas on what to do with this dark residue (apart from burning it or throwing it in the bin), please let me know!
