I saw an interesting post from Tom Sampson on the "Bonbon and chocolate painting techniques" Facebook forum about a device he invented to keep an airbrush warm. Another member of that forum responded that he too is working on such a heater, and the two of them are now corresponding. Such a device might revolutionize the decorating of bonbons.
QuoteI think we are all a bit obsessed with temperature and I have found it particularly difficult to keep the temperature of the cocoa butter in my airbrush constant. I've tried wrapping it in a heated mat and using a hair dryer but I can never be certain that the temperature is correct. I therefore decided to make a heated airbrush and posted my preliminary results on the Chocolatiers Forum on which there was a lot of interest and several questions....I have spent many hours to get to this stage and although it has been suggested I patent the idea (which would require me to make a charge to recover the costs) I am aware that there are many small businesses and hobbyists who are on a limited budget and so I am happy to give anyone the parts list and instructions.
