Rockwool is an item added by Thermal Expansion. It is used as a dyeable decoration block similar to Wool, but is fire proof. It is obtained as Light Gray Rockwool by smelting Slag, while other colors of Rockwool are made by using a dye with 8 other Rockwool blocks. This makes it more efficient to dye than wool, as one dye makes 8 colored Rockwool at once.
