If you want to create your own Refined Quartz, you can do this by smelting 1x Quartz (regular or Fire Quartz) with 1x Coal. To do this both of these items must be placed inside a Furnace, and when the Furnace is done there will be 1x Refined Quartz bar ready to collect (Or three if you opt for Fire Quartz) Of course this does require a Furnace so if you do not already have one you should either complete the Blacksmith bundle in the Community Centre which is located in the Boiler Room, or create the Furnace using 25x Stones and 20x Copper Ores.
