Robert DuGrenier has been blowing glass for over 30 years. His work has been shown world wide. Robert created handblown glass terrarium sculptures to house living art compositions for about 50 hermit crabs. Taking care to pose no harm to the crabs, he imitated the exact interior shape of nature’s shell in each of his hand blown crystal shells, following spiral formations which accommodate the contours of a crab's body. On the exterior he has taken license creating individual pieces of art, fusing the crystal with 24 karat gold, sterling silver or bronze. Though the crab will inhabit its glass home only until it outgrows it and is ready to find its next one, the randomness of where the crystal shell is abandoned adds to the visual dynamic of these installations.
