Sawing/splitting glass concrete blocks?

[Highflower]

Hello,
I've searched both the forum and Google but haven't been able to find information on the best way to cut glass blocks... It’s mentioned on Vetro's website. The blocks are not going to be in wet areas so condensation shouldn’t be an issue, nor should they lose their strength.

I have contacted over 10 glass shops for help with this, but none have the equipment or knowledge on how to do it.

I tried using a diamond blade on the Dremel, it works but it takes a very long time and the cuts aren’t exactly perfect as the blade is so small. I managed okay with one block but the second one I tried cracked. I would need to make about 10 cuts in half blocks of which 6 need to be at a 15-degree angle, see picture.


angled cut

I thought about trying with an angle grinder and diamond blade but haven't dared to try it. It feels like it could be a potential life hazard with exploding blocks and flying glass projectiles. The dust produced also probably isn’t the healthiest...

How would you tackle this problem? All suggestions are welcome except "don't do it"!

They say it themselves on their website: "Then it's difficult to get the cutting to look even and good. Check with your local glazier if they have a diamond cutter that's required. - Vetro" so it's probably not easy to get it right.

I would have tried with an angle grinder and "astronaut suit" if none of the glaziers you talked with had any suggestions for a suitable diamond cutter. Why not contact Vetro and see if they have any more concrete advice.

Wet saw with stand and tiltable table, nothing else you need to test.

Thank you for your answers!
I don’t really require the cut surfaces to be very good; it's more about the time it takes, which is why I don't want to continue using the Dremel. I would estimate that I spent about 45 minutes on the block I was successful with, the same amount on the one that cracked, and it doesn't feel reasonable to do that with 10 cuts.

This is a one-time job I need to do and I don't have the budget to acquire expensive tools. Is it possible to rent such a wet saw? Any tips if so? Cramo has some table saws. Would a tile saw maybe work?
