Some of the Trinity windows below. The majority of the West Front’s old panes, certainly in the non-restored windows, seem to be an early form of cylinder glass, with that typical wrinkled and warped texture like the skin that forms on hot milk:

Yes, most of the remaining old glass in the not-yet-restored windows of the West Front (and its rear, and the east block) is cylinder, with a lesser amount of crown – not surprising as it is a much older method than cylinder.
It would be tragic to lose all of this, but, imo on the evidence of the restored northern block, that’s exactly what’s going to happen unless the situation is intervened upon.

(As you say some windows don’t have that much old glass – just a couple of panes – but overall there is a fair bit left, especially in the upper floors.)

Moving inside to the Front Square and the northern block, and again a mixture of cylinder and modern wavy stuff in this restored window:

I can’t agree with you here Graham. As far as I would be concerned the ‘cylinder’ you refer to is ‘fake old’ glass. It’s some type of agricultural glass, used perhaps for greenhouses and the like. It is used because it looks a bit like cylinder glass. It is just rippley]very odd [/I]pane of genuine cylinder seems to be surviving the restoration (there is one in the middle right of the above pic), but certainly none of the rare and more valuable crown.

I’m pretty sure the ‘wavy modern’ or ‘bendy plastic sheeting’ (good description!) glass – which makes up the majority of glass in the restored windows – is also new; it looks new and it doesn’t seem to exist in any of the not-yet-restored windows. As you hint, perhaps it is intended as a (crap) imitation of crown glass?

This also, as far as I would be concerned, is the ‘fake old’ glass.


So, in short (I think), all of the former very-flat-modern / cylinder / crown glass of Trinity’s windows is being replaced with a combination of wavy-modern and fake-old glass, with maybe a very small amount of genuine old being saved and reinstated.

The reason for this I reckon is – just like so many things in Dublin at the moment – a need for speed … the number of windows to do versus the contract deadline; when they’re dipping the windows, removing the paint, splicing in new wood etc. it would just take too long to remove the old glass without breaking it … easier to just knock it all out and put new glass in when the work on the sash frame is complete …

The job is proceeding apace. As I said earlier, having completed the northern block, they’ve now moved onto the southern block, and in the last couple of days, a load of sashes have come out of the 2nd floor of the square facade to be taken away for ‘restoration’.

I’ve spoken to the DCC Conservation Officer and also a DoE conservation official and the situation is going to be investigated on Tuesday. Will update.
