The Chemical Fusion Chamber is a 13x5x13 (width-height-depth) multiblock structure added by MineChem which allows the player to fuse two identical or different elements together to form an element with the sum of the atomic numbers.
For example two Hydrogen (H) (atomic number: 1) can be fused into one Helium (He) (atomic number: 2), and then two helium into one Beryllium (Be) (atomic number: 4). Or two Iron (Fe) (atomic number: 26) into one Tellurium (Te) (atomic number: 52). It is a method to produce rarely or not collectable elements.
In order to operate the Chemical Fusion Chamber, RF energy has to be supplied. This can, for example, done by means of generators of BuildCraft (shown in the picture). The chamber has also a storage for 100,000 RF.
To use the chamber, right-click anywhere on the multiblock to open the GUI. On the right side are three tabs: the first shows the energy storage of the Chamber, the second shows a short description of the Fusion Chamber, and the third is to support the authors. In the middle is a line at the top that shows the energy storage of the chamber, and below are three slots. The slots on the right and on the left are for the elements to be fused. The product appears in the middle slot.
The energy consumed is dependent on the elements to be fused: the heavier the elements to be fused, the more energy is consumed. (RF per product needed = periodic number of the desired product multiplied by 100)
