The brown colour of this style results from reactions between several of the elements that are listed as reactive with one another elsewhere on this chart. As such, it may react with many of the other glasses that contain these elements. However it is likely that the reaction will be subtle or unnoticeable due to similarities in the colour of the reaction and the colour of the glass.
