I would load the volcano with ash or in the beginning I would use a small bed of marijuana, I'm leftover with this black hard leftovers, recently I've had no Spice so I tried using the leftovers and have successfully broken through re using it. anyone have any experience, thoughts, ideas, concerns about this?

Its obviously more harsh.

Secondly. I thought the volcano may have been the ultimate, But I would say the big downside is the spice coats the inside of the bag and I wonder how much losses occur. (Will attach photo if wish to see)

What is the ultimate tool?

The Volcano might be the ultimate tool for Cannabis, but not for everything else. Spice has a different vaporization temperature than Cannabis does. I'd recommend the Glass Vapor Genie and a good torch lighter with a single torch. This seems to work really well for most people. Or you can search to find out how to make a 'machine' type device and use that, but IMHO the Glass Vapor Genie is the easiest way to go. AND it also works really well on Cannabis, hash and oils. You just need to learn how to adjust the temps by keeping the torch flame a certain distance away from the top in order to dial in the temps that are best to vape what you have loaded.

Good luck

you absolutely have to use a liquid volcano pad for spice, then it works great

Yes I would use the hash pads, & volcano's have the ability to adjust the temperature....Temp is not the problem its that it coats the bag..
