The Magma range involved placing molten glass that had been coloured black onto a sheet of gold leaf. The heat of the glass and the subsequent blowing out of the piece would cause the leaf to crack. No two pieces were ever created the same as there is no control over the cracking of the leaf over the glass. Clear glass would be added over the top creating solid paperweights and perfume bottles. The range was named magma after the likeness to the molten rock and metals associated with volcanic magma.
