I just received a new granite surface plate, probably originally from China. It’s 40x25x8cm. Weighs around 23 kilos. I’ve been wondering what I need to know about taking care of it. I plan to keep it covered with part of the 1/8 in. plywood it was packed in. I know it has to be spotless clean when I use it, but should I put anything on it when not being used, like oil or wax? Also, I’ve seen that for large ones they should be leveled using three points. Do I need to devise some adjustable support for it, or because of it’s small size, will it be alright just sitting on a flat counter top? Is there anything else I should know?
Thanks
