Glass carboys breakGlass carboys can break and cut. Use a good carboy handle and always support the bottom when you move a full one; a crate or carrier under the base helps on slippery floors. Never pour hot wort into cold glass. PET and stainless avoid the risk.Source: Craft Beer & Brewing: Homebrew safety
