Sand Art in Blooming Baroque
An entire city of sand will be built this summer in the Blooming Baroque - Ludwigsburg! How will the international sand artists stage "our" city? Which buildings are made of the unusual material? In the castle garden visitors can watch live how the huge sculptures of several hundred tons of sand take shape.
Why do sand sculptures last so long?
Many have ever built a sandcastle on the beach. With wet sand that's pretty easy - but once the sand was dry, there was a risk of collapse. But why do the sculptures of the Sand artists last so long?
The sand artists, also called Carver, do not use the normal sand from the sandy beach, because it is very old and already washed by the tides. It is about as good for building as if you were trying to stack tennis balls. The sand used by the carver must be square and sharp-edged.
Of course, the sand slumps of professionals are also larger than normal sandcastles that you build on holiday ... but you must also take into account that for a figure 30 tons of sand and more are used. Before the carvers can get started, the sand is compacted layer by layer. And that takes quite some time, because only small amounts, ie a layer of about 30 cm thickness can be compacted, because it is very important that the sand is very compact afterwards. During compaction, the angular sharp-edged grains of sand interlock perfectly and "hold each other" firmly.
The carving of the sand sculptures is then always from top to bottom. It is important that there is a "loose" layer of sand at the bottom, where any rain can drain well and seep through.
Some carvers then sprinkle the figures with a protein-containing liquid that lays like a very thin skin around the sand sculpture, but is still biodegradable. This invisible skin gives a temporary additional protection against heavy rain, so that sand sculptures are extremely durable.
