I learned long ago not to bash the crap out of tiles your better going at it slowly. Get your bowster at one edge and tap easy, the vibration through the tile will make the job easier and lift more adhesive for you
Engineering workshops use big mechanical hack saws, the blades are 2" wide and couple 3 foot long. If you get hold of an old one cut it into 3 and sharpen one end like a chisel and use this to tap tiles up. Because of the type of steel and the thickness about 3/8s they are awesome for the job
Dont envy you tho and you need goggles on this one
