Please note that slate is a natural product and may contain small areas of gold, natural flaws such as riven areas, hairline veins etc. Being a natural stone product it may have sharp edges/corners and imperfections which will make them look more rustic and does not have a smooth shiny finish.
The plaque is made of slate which is a natural product.
Slate absorbs water. As we are using engraving technology (slightly digging into the product until changing the texture and colour) not printing, that makes the writing look faded when gets wet.
The product has been created for outdoor. However, it requires a few minutes to get dry in order to look as in the first day.
