Can you use limestone for a fireplace?
You cannot use limestone for wood-burning fires because it isn’t as heat-resistant as granite, but it is still durable.

The stone becomes a grey-white powder at 800- 1000°C (Chakrabarti, 1996). The calcination of calcium carbonate begins at 600°C and proceeds rapidly beyond 800°C. The strength is reported to reduce once calcination occurs. The intrinsic strength of the limestone is reported to remain unchanged in small fires.

What is limestone used for?
Limestone is used in the construction industry in various applications including new structures and in restoration of historic stone monuments. Exposure to fire and high temperatures cause significant changes in the physical and mineralogical properties of limestone. The aim of this research is to propose a strategy to assess the fire and high temperature performance of limestone. The proposed strategy is supported with preliminary studies conducted in Malta and in Hungary to assess the fire and high temperature perforamnce of different limestones. Furthermore the aim of the research is to conduct a comparative analysis of the performance of Maltese and Hungarian limestones when exposed to fire and high temperature, within the framework of the strategy.
Where is Globigerina limestone found?
Globigerina limestone blocks are extracted from the Lower Globigerina geological formation in Malta, and are used primarily in the construction of load bearing masonry walls. Globigerina limestone is extracted also for other applications in the building industry namely cladding elements. The stone which is extracted from open-pit quarries using mechanical saws is relatively soft and yellow in colour. Variations in quality of Lower Globigerina Limestone is reported from different quarries located in different areas in Malta , and also within the same quarry with depth. The Upper and Lower Coralline limestone geological formations are mainly exploited for the production of aggregate and civil engineering applications. Specific formations are also exploited for the production of cladding elements. Blocks extracted from specific coralline limestone formations were traditionally also used in specific cases in buildings due to better durability and strength of the materials and imporved weathering resistance qualities when compared to the soft globigerina limestone. The upper Coralline Limestone and the Lower Coralline limestone deposits are subdivided into different members. The scope of the first phase of the investigation is to review the main performance characteristics and to define the main paramateters for more detailed investigations. The materials were selected as representative materials of the two main types of limestones, as summarised in Table 1. The Globigerina limestone samples were extracted from rectangular blocks sampled from the same layer in a specific quarry. The Coralline Limestone samples were extracted from boulders extracted from an Upper Coralline deposit in a Coralline limestone aggregate quarry in Malta.

What causes salt to move in limestone?
Rainwater, especially in combination with atmospheric gases often resulting in acid rain can result in dissolution of the limestone, causing higher levels of salt movement within the stone structure.Temperature can effect rates of deterioration and (in larger stones) movement of the pieces, as well as patterns of salt migration within the stone. Most of the natural or inherent problems which can occur with limestone require some degree of moisture to occur, however other problems such as wind erosion and vandalism may occur independently.
