I want to use a piece of glass for a paint palette but it has to be colorless to be able to judge the colors I mix.I will be taping a piece of paper behind it but the glass i purchased has a green tint to it. Is there a colorless glass to buy.?
Thank you for contacting the Glass Detective with your question regarding some help in finding a glass product that does not come with any green tint (which virtually all glass does). The glass you are looking for is known as a low-iron glass and is used by the furniture industry and in some architectural applications as well. It is virtually clear with no green tinting of any kind. This is achieved by changing the glass manufacturing formula and eliminating the presence of iron in the raw glass formulation. It comes in a full range of thicknesses and is easily cut to size and fabricated. You may want to consider having it safety tempered as well if it is going to be handled at all. Tempering should not affect the clarity whatsoever. A glass shop in your area may either have something readily available or can probably get it quickly from a wholesaler.
Thank you for contacting the Glass Detective. I hope this information proves useful to you.
