"This is a Scrabo sandstone church, but one that has undergone little conservation. It exhibits a variety of decay types, including the rapid retreat of individual blocks. This occurs when a block loses an outer layer of material through, for example, the falling away of a large scale. The effect of this is to produce a hollow in which salts can continue to accumulate because it is sheltered from rainwash. This salt accumulation, combined with the higher humidity in the shadow of the hollow, creates an excellent environment for accelerated decay. This reinforcement process is known as 'positive feedback' and it means that once decay is 'switched on' in these kinds of weak sandstones it becomes very difficult to turn off.

Part of the detailing on the church includes a string course of Doulting limestone. This is a potential source of gypsum for the quartz sandstone, and it is possible to see how this has lead to the decay of blocks below the limestone. Gypsum can also wash out of the mortars and this can lead to the formation of gypsum crusts on the top parts of stone blocks. The final feature is the growth of algae and lichen on many blocks. There is anecdotal evidence that this greening of sandstone buildings has become widespread across Northern Ireland over the last couple of years and you will see other examples on buildings such as the Elmwood Hall at the other end of the Avenue. Recent work by the Weathering Research Group has suggested that this greening may be linked to changes in weather conditions in which winters have become milder and wetter. This has resulted in stonework remaining saturated for long periods of time, which in turn might encourage biological colonisation and growth. Whether this represents a short-term effect or is indicative of a longer-term change in climate will take more research. However, if it is indicative of a permanent environmental change, it might mean that we have to change many of our ideas about building stone decay. The frequency of the wetting and drying of salts could, for example, decrease and with it the effectiveness of salt weathering. But we would have to take the effects of biological weathering much more seriously. Likewise, conservators may find less call for the treatment of gypsum crusts and a greater interest in the effectiveness of biocide treatments."

Part of a road trip from Niagara Falls to Key West - taking the long route close to the Atlantic, so here passing through the Outer Banks of North Carolina.

The Outer Worlds is a new single-player first-person sci-fi RPG from Obsidian Entertainment and Private Division. Lost in transit while on a colonist ship bound for the furthest edge of the galaxy, you awake decades later only to find yourself in the midst of a deep conspiracy threatening to destroy the Halcyon colony. As you explore the furthest reaches of space and encounter various factions, all vying for power, the character you decide to become will determine how this player-driven story unfolds. In the corporate equation for the colony, you are the unplanned variable.

I love the creating dance themes that Autopilotpatty Poppy creates for her lovely events. Here the lovely Darlingmonster Ember and Solace Fairlady do outer space dances.
