all that you see in the picture cost me £9.90 ha ha, that was the price of the aquarium sealant. my uncle is a glass cutter and has his own business so that cost me a bottle of wine.
its just normal glass of 8mm thickness, toughened glass ive heard is a big no no as it smashes rather than cracks.
think im going to need that luck but all i can do is do my homework and give it a go (also test it outside ha ha)
