I can't seem to find an answer for the torches melting radius other then ice melts at 12 light.  I know the torch puts out 14 light.  Reason for the question is I am using ice as a method of conveyance.  Its underground so I want to have the area well lit so mobs wont spawn in the area.   So how far do I need to make sure the torches are from the ice?   Figure a more experienced minetownian would know <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>
