Ice Sculptures

Ice sculpture is a form of sculpture that uses ice as the raw material. Sculptures from ice can be abstract or
realistic and can be functional or purely decorative. 

Ice sculptures are generally associated with 
special or extravagant events because of their limited lifetime.

The lifetime of a sculpture is determined primarily by the temperature of its environment and thus, a sculpture can last from mere minutes to possibly months. There are several ice festivals held around the world, hosting competitions of ice sculpture carving.

The temperature of the environment affects how quickly the piece must be completed to avoid the effects of melting; if the sculpting does not take place in a cold environment, 
then the sculptor must work quickly to finish his piece. 

Some sculptures can be completed in as little as ten minutes if the carver is using power tools such as chainsaws 
and specialty bits fitted to a die grinder.
Tools used
Ice sculptors also use razor-sharp chisels and hand saws that are specifically designed for cutting ice.

As various technologies are adapted for use with ice carving, many sculptures are now created largely by machine.  
CNC machines and molding systems are now commonly used to create ice sculptures and complicated logos from ice. 

Color effects are also possible by a number of techniques, including the addition of colored gels or sand to the ice.

Sand Art


You would have probably made a sand castle in the beach sand  or in your house itself during summer holidays 
using buckets and tiny shovels during your childhood days. 





Sand art works on the same premise, 
but it is much more advanced than what most of us did as children.
Each sculpture has got its own uniqueness.
Sand art is the practice of modelling sand into an artistic form, such as a sand brushing, sand sculpture, sandpainting, or sand bottles. 
A sand castle is a type of sand sculpture resembling 
a miniature building, often a castle.

The two basic building ingredients, sand and water, are available in abundance on a sandy beach, so most sand play takes place there, or in a sandpit. Tidal beaches generally have sand that limits height and structure because of the shape of the sand grains. 
Good sand sculpture sand is somewhat dirty, having silt and clay that helps lock the irregular shaped sand grains together.

Sand castles are typically made by children, simply for the fun of it, but there are also sand sculpture contests for adults that involve large, complex constructions.
