Keeping chocolate in temper

Nicole, the water is almost simmering (steaming lots), and we are using 8 litre stainless steel bowls and large stock pots. The water never touches the bowl, and the bowl sits very deep into the stock pot.
Heat guns put out very high, and very direct heat. You can actually burn the chocolate with a heat gun. You want gentle and uniform heat on your chocolate, or you'll get streaks. The only place my staff use forced air heat (from hand held hair dryers actually), is to clean the chocolate off the machines throughout the day, but never on the chocolate itself.
Below, Mark suggests what we call "reverse tempering" (my personal term), where you have over crystalized chocolate, and are introducing into the mix, chocolate that is uncrystalized and is in the process ofcoolingdown from being completely melted (40 degrees +). I also teach this technique to our staff, although I usually suggest that they let the chocolate cool a bit more - usually to 95 degrees - before adding it to the existing, over-crystalized chocolate. This way, there's less risk of pulling the over tempered chocolate out of temper. I also suggest that they cool the over tempered chocolate a bit more - usually to 87 degrees just before they add the new product.
The temperatures Mark is suggesting could also be directly related to the amount of melted chocolate he's using VS. the amount of over-crystalized chocolate he has, and what temperature it's at too. In our case, it's usually a ratio of 30% over-crystalizedto 70% melted chocolate.
The next step? Stir, stir, stir, then stir, stir, stir, then wait 5-10 minutes for the crystals to seed, or you'll get streaks.
Cheers.
