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.
Copper sulfate and copper oxide are two important copper compounds used in industry and agriculture. Copper can be mixed with other metals to form alloys, such as bronze (copper and tin) and brass (copper and zinc). Oxidized copper, or copper that has been exposed to air, develops a green coating or âpatinaâ that can be seen on old copper pennies, the Statue of Liberty, and copper roofs.
