Gotcha, some similar cracking happened to me a while back (see my post history; it's El Bongquistador). Sucks, dude, but it'd probably be advisable to start again, and use a diamond-tipped drill bit to make the hole for the downstem. It looks like you're using a 9mm bowl or something on the smaller end, so you could use something like this and rent a drill from Home Depot or something to that effect to make a cleaner cut. If it cracked pretty badly as you suggest, there's likely a risk of microshards being mixed into the water and aerosolized by the bubbling as you pull and it's not worth cheaping out on proper tools at the expense of your lungs.

If anyone is interested in doing this, this is the bit you need from Amazon.

Just spray it out, drill a little, spray it out, etc. Ceramic bits don't like to be gunked up with the dust, and water helps. The bit I have is about 3/4 inch, I've never tried starting small and widening. There are different types of bits for different types of tile/stone/etc, but mine look like this:

It looks like what I do is different from what everyone else is suggesting but...

I use one of these bits. To start the hole, Ill put 2-3 layers of painters tape down and drill through that. It helps keep it from sliding around.

As for speed/pressure/heat. I go full speed the whole time (stopping occasionally to get the dust out of the way and check my progress). The only pressure I apply is the weight of my drill. Just enough to grind away. As for heat, I'll only drill 2 holes and then let the bit cool for a while but Ive never used water to cool as Im drilling.

I've gotten perfect holes ever since I switched to a non pointed bit and have never shattered a bottle so I hope you get some of the same luck!!

You mean like one of these? Might pick one up if you say they are better.

Okay that would do the job!! Gah I was going to do a single, large center hole with my angle-grinder (and put steel mesh over that) as I've got a plant needing re-potting and really want to use this one if possible, I wonder if I can find a bit like that locally am going to have to make some calls!

I was thinking you'd start out with 1/8" bits and then work your way up, boring bigger holes each time- if there's a 'doorknob'-type bit for ceramic that'd be ideal for me, would put a ton of 3/4" holes and call it a day! Time to see what local shops have because if I can't buy locally I'll probably just use the angle-grinder as I want to re-pot this guy right while he's starting to flower (right now is 3 days into setting flower buds)
