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.
Now, when copper is combined with other metals the end result is an alloy. Both bronze and brass are examples of copper alloys. They too play very important roles industrially. The primary difference between the two is that brass is made out of copperâs combination with zinc while bronze is literally copper plus tin. As mentioned, copper is now popularly used in many industries but for it to become more useful, it needs to be combined first with other more stable metals. This is because copper in its purest form is just too soft. This is the same reason why bronze and brass came to existence. Historically speaking, bronze is an older alloy because it is said that it was already discovered as early as 3500 BC.
