Dear FC members,
As the designer and manufacturer of Da Vinci, I would like to address the comments regarding mystery vapor and offer this comprehensive response. The mystery vapor which few have seen is a short term purification process of an organic rock based insulation material called Mica (
http://en.wikipedia.org/wiki/Mica) which if not fully 'burned in' will continue to burn off the impurities until cooked away. Because Mica sheet is an organic rock compound, the amount of dirt and sand (impurities) varies inch by inch and can leave a larger deposit in one application over another. The purpose of the Mica Sheet is to insulate the heating wires from the metal bowl (this keeps the bowl from passing electricity to any metal object you might stick in it).
We chose to use Mica sheet insulation because it is well proven in the consumer and vaporizer industry. It is used in your oven, microwave, lanterns and other vaporizers because it insulates electricity and is an organic material that is stable in high heat environments. We also feel the organic compound is a better choice than the adhesive backed synthetic insulating jackets that are also offered.
All manufacturers employ a 'burn in' process and as a result to comments on mystery vapor, we have doubled our 'burn in' time to further eliminate these impurities. This additional burn in time has curbed all issues. But if there was any remaining organic vapor, it is because we use several Mica layers wrapped around the bowl and occasionally a collection of debris may take longer to burn off.
Da Vinci is one of very few brands who actually own and operate their own dedicated manufacturing facility so I take great concern on the materials brought in and our QC processes. We are engaged with the vape community in an unending effort to raise the bar and help bring the best products to market. In the end, we are a dedicated group of like-minded souls who wake and breathe the dream of building the ultimate vaporizer and we respect your insights.
So along with these elaborate explanations, I thank you for the scrutiny. Such comments have tuned our ears and I have buried myself in 'bowl research' for the last year. The cumulation of my research has led us to develop the most advanced glass on glass portable vape (
www.davincivaporizer/Ascent - coming this March) with great detail to a consistent bowl temperature and uniform heat. The pure taste will be a 'first' in the industry and with a 4 hour battery in a device smaller than the iPhone is a testament that we are listening to a committed vape community.
Thank you again for your continued support and respectful comments.
