I do like coloured glass and use it when I can. As well as the cathedral glass, I quite liked the look of brilliant cut glory stars and found someone who could do this reasonably locally. So finally got the glass and spent today glazing the door. Tools and materials today are about 2 kg of linseed oil putty, a few bashed pieces of white chalk (whiting) and a paintbrush, glazing points (also maybe pliers and snips if the ends are a bit long), an old paint scraper with a tidied edge and face and a card scraper.
First thing is to take the skin off the putty and discard
Get kneading in your hand for the warmth and if it's too oily, then onto a piece of cardboard.
Putty goes in the rebate (the rebate should have barrier finish on it to stop the oils being sucked out of the putty too quickly. In this case they were finished with boiled linseed oil. This can be done immediately before if needs be)
Glass is shimmied into place. Cut side and textured side of cathedral glass always faces the rebate as you need as flat a side as possible to get a decent looking putty moulding: any undulations will transfer to the putty knife/paint scraper.
Glazing points are waggled home. Pressure on the glazing points with some side to side motion usually seats these. Wouldn't advise bashing the end of the scraper with a hammer or even a mallet, not just for the glass but as these are easy to bend. Oak can be tricky to penetrate with these but if so I just move the point somewhere else.
Get the chalk on straight away to get rid of oily marks and before the putty goes off. This is easy at this stage. The chalk also helps the putty skin a bit quicker. Just go easy with the brush on the edges. I try and line the putty up just a hair under the width of the rebate so a tiny amount or none of the wood shows. This is because paint applied later needs to go beyond the putty and onto the glass and at that stage should ideally line up the the rebate.
I find a card scraper on the other side good to get the corners clean. Don't forget to chalk this side too.
Here is oil smearing around the edges before chalk
And about 20 seconds later. Come back with the scraper to clean the chalk out of the corners
Needs a wee dusting but the outside is ready to finish
