==Description==An item used to limit access to a mine''A door made from the purest silver.''

=A '''silver mine door''' is an item used to limit access to a mine. ==Usage===*Activate the mine door, right click a mine tile border and select ''build Build door''. == Maintenance == Once installed, the silver mine door slowly loses strength if off deed. To keep it from decaying, it has to be repaired. To repair the silver mine door, activate a [[silver lump]], right click the mine door and select ''Improve''. The lump does not need to be glowing hot to be used. The maximum strength you can improve a silver mine door to depends on the silver lump and your blacksmithing skill. The formula is 100 * (Lump QL / 4 + Blacksmithing skill / 2).  Each improvement uses 0.1 kg of the silver lump and raises the strength of the mine door by a fifth of the difference between current strength and maximum strength. The following graph shows the decay of a silver mine door over the course of over a year. The Mine door has been repaired a few times since.The decay has been about 28 strength per day on average over the whole period of 400 days. [[File:Silver mine door decay.png|Decay of a Silver mine door]]
