Drying chems

[Tim1877]

Just wondering what chems are safe to dry in the oven if any at all I know no mixed comps but what about single chems one at a time?

While I’m no chemist of any sorts. You shouldn’t have any issues with Supplies for BP on a low setting in an oven so long as they are done individually. An out door drying box would probably be better for most granular materials though. Airfloat charcoal you’re a little stuck to limiting circulation while heating it to dry.

 

I’ve venture to think that most of the basic chems we might use could be dried the same way, but you could always look each one up you wanted to dry and look for clues. Like below link lists melting and boiling points so with this example 150F should be no issue at all.

Will depend of the kind of oven and material also. I converted 300g of charcoal to a big red ember in a toaster Owen. The thermostat could not be trusted in a toaster oven, and the heating element irradiate directly over what you have in. Since then, I use an oven tray covered with perforated aluminium foil, and control the oven with an external thermostat with a termocouple just inside the ingredient to dry. I get an hysteresis of +-5ºC, and can get lower if I lower a little more the power. The advantage of this oven is that is cheap, dedicated only for this purpose, and I can place it anywhere with a plug. Cheap and mobility means that I can make some "dangerous" experiments if needed. I just put it in the "bunker".

 

A convection oven will be better since will not heat directly the material to dry, but will be much more expensive and difficult to move.

 

What I will never do is drying pyro chemicals in the kitchen oven. Don't mix food and pyro, except when you make an spectacle for a celebration.
