Hydrofluoric Acid Updates & Plastic

Hydrofluoric Acid now reacts with many more things, including Ceramic Walls! To contain Hydrofluoric Acid, you can now create plastic (PTFE - polytetrafluoroethylene) and build walls with it. Ethylene now is one of the things that evaporates from Naptha (product of separating oil), and is used to produce TFE (tetrafluoroethylene) and then PTFE.

List of new things Hydrofluoric Acid reacts with: Alumina, Apatite, Corundum, Flint, Magnesium Oxide, Olivine, Quick Lime, Rust, Zinc, Zinc Oxide

Enthalpy

Exothermic/endothermic reactions are now more realistically simulated, using an Enthalpy value (in Joules) instead of a TemperatureChange value - this allows the temperature change from reactions to act properly with regard to Specific Heat of the material in the cell. The Guide Tab shows the delta-H (Enthalpy) of reactions that have an Enthalpy value.

Heat Pumps

The first iteration of heat pumps, based on suggestion from the Discord, is in the game now. :) These pixels move only heat. They will probably become more important as the heat-modeling of the game becomes increasingly realistic. :)
