first of all... what kind of glass do you think I should use? I was thinking about making a smaller vaporizer and use the smallest glass... but i want to know what do you think? ok... the second point is the soldering iron potency.... I want to use one like these: "Adjustable temperature control from 175 C and 480 C" the temperature is perfect, dont you think? I could even open the plastic box and place the dimmer in a wooden box..... then another day, I'll choose the woods sorry about my english
