As our signs are hand made using traditional enamel techniques, our craftsmen use powdered enamel which is prepared in batches using natural materials. This results in the chance that minor variations of color could occur between the batches. Also the environmental conditions at the time of firing the sign in the kiln will impact the final result in a subtle way. If you want two signs to appear more or less exactly the same, please order them both together so that we can produce them in the same batch.
