Check out our Bar Essentials range of laboratory glassware which we have had specially made in extra thick borosilicate glass so that it withstands use in bars and restaurants. Our laboratory glassware is ideal for serving Harry Potter, Breaking Bad or mad scientist themed food and drinks. We also supply a wide range of gelling and thickening additives which can be used to create interesting textures and effects in food and drinks. Our 'colour changing' Magic Blue colouring actually changes colour when acidic liquids are added to it!
