I guess there isnt any, but in my experience, there is no noticable difference from different blends of changa and pure DMT, atleast not to me, unless there is salvia divinorum in the changa, which there often is, people cut their changa with salvia and pass it off as the real thing, atleast here in scandinavia, when i get that type of blend there is a major difference, but from one herbal mix to another its more or less the same, to the degree dmt trips can be the same
Copper has been used and cherished for around 9,000 years. Pots that are made of copper are ideal heat conductors; the material is durable, hygienic and corrosion-resistant. Above all, it is the excellent heat conductivity that makes copper a perfect base material for pots and pans.
Note that heating a seasoned cast-iron pan to above 800-900 Â°F will probably burn off the seasoning, and nonstick coatings will typically burn off around 500 Â°F or so. Aluminum melts around 1200 Â°F, and copper around 1900 Â°F. Copper-clad pans will probably declad at much lower temperatures. It's unlikely that you actually have a pan made out of solid copper; most copper pans are actually copper clad. The failure temperatures of glass cookware are all over the place. Old Pyrex glassware (the genuine stuff made from borosilicate glass) should be good to around 1000 Â°F (borosilicate melts at around 1500 Â°F but starts to flow well before that). The newer stuff (basically anything since about 1995) is made from tempered soda lime glass and is only really safe to around 550 Â°F.
