- TOXIC GOLDby 76561199365498658Turning lead into gold is a well-known process in modern alchemy. However, in the early days, many transmutation attempts ended up with toxic products.

- Synthetic rubyby EarthfireWhile most of house colvan 's earnings came from trade routes around the world, it is surprisant for some that the most recent developments were in the area of waste management.

- GLYPH OF UNBONDINGby 89oAnother glyph of transfiguration crucial to the operation of the transmutation engine is the glyph of unbonding. Unlike the glyph of bonding, created using strongly lubricating tin, the glyph of unbonding is made out of the finest gold. This is specifically because of its separation properties, w...127 downloadsupdated 8 y ago

- EXPERIMENTS IN REDISTRIBUTION Iby 76561198384240744It is well-known that the most common transmutation operations, bonding and unbonding, require an arcane power source. However, operations on individual atoms, such as calcification and duplication, use only the power stored within the affected atoms. Because of this, some specific alchemical tra...127 downloadsupdated 15 mo ago

- DragonsBreath 02: From Theory to Practiceby cake>pie... at that time, theorists believed that the volatility of the triplex bond could be increased by leaving the bonds partly incomplete. However, while it was clearly possible to do so within the confines of a transmutation engine, only completed bonds could be accepted as output. For a long time,...123 downloadsupdated 9 y ago
