Hi Andy - Never ever raise any oil to boiling point as this is a fire hazard as the fumes given off will be above the liquid oils flash point. I only posted the oil method of drawing the hardness down as this does not need any special equipment other than a suitable source of heat and a container. Olive oil and many others edible oils smell very good where as mineral oil is not good and is probably poisonous.

The domestic oven is ok but in my experience the temperature need to be watched all the time as the oven themostats are not precise so the temperature wanders up and down quite a bit. I use an industrial glass / mercuary thermometer that is in a protective steel tube. The oils are from the supermarket or the local deli.

Regards - Pat
