Arguably, you could say that you make the soap in the pioneer fashion by using lye made from the ashes of a fire and dye from berries and fragrance from tree sap, blah, blah blah. You still have to light the wick and you still have combustion which still emits cancerous fumes into the atmosphere. Just smile and say, "Oh how wonderful for you". what else can you do? The average customer is not overly concerned with emissions; I mean really they aren't. Thank goodness it's a diverse market place out there. Steve
