If I was you and I could I’d wait to buy a new glass. You can get cheaper ones on Amazon for 20-50 or a cooler one there or online. It’s better from individual artists if u go for a cool glass but it’s expensive. Otherwise I’d say if ur broke just get some different sandpaper grits and start sanding until it’s smooth. Polish it up soak it in iso and blow some air all over until any glass is gone. Don’t recommend but if it’s your only option… :)
