Yes to your query 'derrynoose'. Buy a glass/china drill from your DIY shop,
stick a patch of masking-tape, about 1" square on both sides of your plate where you want the hole, mark the centre with a felt-tip on the front of the plate (the patch on the reverse side helps to stop flaking of the hole when the drill comes through. Put plate on a tray of damp sand or something similar to ensure a firm surface. Use a power drill at SlOW speed and gentle pressure, cool the drill bit in some water if it gets too hot. The masking tape patch will help to keep the drill steady when you start off. Have patience and good luck .
