- In this video Sophie shows you how to make your own cement for leaded stained glass windows. Never be caught out again by cement that's gone dry at the bottom - or even worse - dry all the way through! With this recipe, mix just the right amount whenever you need it! It's easy (when you know how)!

When you’re done with the putty, if you add a layer of linseed oil on top it will not set off for quite awhile. Then you can pour it off when you’re ready to use it again.
I'll give it a go - thanks!
Exelente
Thank you Sopie 😃👍 excellent vid.
I'm in Australia & so sick of my putty going off... I made yr recipe & Love it thank you. You have saved me money & putty 👍👍👍
Wonderful!
Thank you! I was searching for the same recipe my old bosses had me mix (putty wench!) and only found weak ones. Thanks again.
You'll find other recipes from my research in my book.
Love these time & money saving tips. I really enjoy your videos. Thank you!
You are so welcome!
That windows look great! thanks for sharing
My pleasure!
Excelente gracias.
Pleasure.
Thank you
Thanks so much for that video. 😊
No problem 😊
beautiful video thank you
Thanks for visiting
Interesting to see what other materials are used. I use neat ordinary Portland cement, black mortar dye, oiled linseed oil, a tad of white spirit & a few drops of terabine driers. It’s worked great for me, for well over 20 years.
Thats so different to all the recipes I've heard of. Like you say, really interesting!
I use Cornelissen's Mars Black.
Hi Sophie, great informative video! I've been buying cement for 20 years and you have inspired me to make my own... Is the black dust Mars black or graphite? Thank you, kindest regards, Carole
I buy Mars black - the denser the pigment, the less you need. I've tried them all and they are all ok. Love your work, by the way. Sophie.
@@SophiesStainedGlass thank you so much :)
Hi Sophie
Thanks for your reply, but its the plaster of Paris that is the concern. Plaster actually sets hard so it would make your formula harder than it perhaps should be, but also the main reason for my question is that it is water activated and will not actually harden in your mixture until is has been in place for a while. The water in the atmosphere then starts to make it rock solid.
I'm just wondering if it is an unnecessary addition?
Also have you ever experienced the mixture setting into hard lumps immediately if you add too much white spirit?
Have you ever made with just boiled linseed oil and whiting
Regards
Colin
I know from using my cement that it never completely sets so I assume that the whiting is keeping is a bit soft. I have never had it go lumpy when adding white spirit. I haven't tried changing the recipe as all my panels go into buildings and I wouldn't like to risk it. It seems to work well as is. So what's your recipe? Sophie
Thanks for the Chatter Glass tip - really good. What's your company called...I'll look you up. And just to add further to our cement conversation, I had to rebuild a window that I had restored 4 years ago and I was really pleased with the texture of the cement 4 years on. Firm but not hard/brittle. S

I found this and thought of you - quite a few different cement recipes. Very interesting. chatterglass.wordpress.com/2019/12/29/leaded-light-cement-formulation/
Ps those windows at the end look amazing fantastic job thank you for Sharing with us X
Thanks so much 😊
Hi, is it the lamp black pigment from Cornelissen? Thanks.
I use Cornelissen's Mars Black.
Does the cement you made here keep a while or only good for the job in hand? I’m guessing the plaster will make it set in a tin if kept?
It will be good for about a week.
Hello, my teacher, I have found most of the cement ingredients, but the black powder pigment is not available in Algeria. Can it be replaced with liquid paint pigment?
You can use grate black.
will this keep in the tub the same amount of time as the one you buy?
Probably.. I'm not sure really. Perhaps you could tell me if you find out.
Hi, I dont understand why you add plaster of Paris. It is activated and chemically cures with water so why add it? Please let me know
I'm no chemist but my understanding is that the mix of whiting and casting plaster gives you a mix that will not set but remain a little soft, thus allowing the glass to expand and contract without cracking. Without the plaster, the cement would never set at all. Without the whiting it would set like rock. Does the answer the question? Sophie
@@SophiesStainedGlass the plaster sets up hard and is hydroscopic. The linseed oil i what sets up the whiting.
You said 6 to 2 on the dry but ended up measuring 1 to 2. So that is ok?
You're the only viewer that noticed! Better 3-1...but it's ok really. Theres all sorts of recipes out there.
The rule of thumb is the more movement you need, the less plaster you add. So an internal panel can stand more plaster as it's less subject to climatic change.
Yes I have noticed lots of versions. One just used whiting and linseed oil. Currently, I want to use it on a long bookcase or cupboard door with long panes of glass. There would be movement with opening and closing but not weather related extremes. Would 3 to 1 be best then? Thank you for your replying.
And yes your panels are brilliant!
@@debbiepring2236 yes
couldn't you just use commercial window glaze like Dap #33 and add pigment?
Yes you can.
@@SophiesStainedGlass thanks
