Can I make wax by making a really potent tea then filtering it and evaporating the tea?

Can I make a super potent tea with grinded up buds using water and butter I'm using butter so it will absorb the THC but idk if the THC will go through the coffee filter or if it will stay on the side with the weed and not go through second question is can I take that tea and put it in a Pyrex dish and double boil it and make it into wax
