 LEADLIGHT CEMENT RECIPE AND CEMENTING PROCESS

CUT & PASTE INTO YOUR WORD DOCUMENT

DRY INGREDIENTS :    4 parts WHITING       WET INGREDIENTS :  1 part LINSEED  OIL  ( 1/3 )

                                    2 parts PLASTER                                          2 parts TURPENTINE  (2/3 )

                                   1/4 part BLACK OXIDE                                                            

                                   1/4 part PORTLAND CEMENT

**********PLUS   AN EXTRA MEASURE OF WHITING                                         

METHOD :     

Mix only as much putty mix as you need for the job.

Mix together dry ingredients and with the premixed wet ingredients form a consistency resembling something between honey and porridge. Using a soft brush (something like a shoe polish brush ) spread the putty mix over your leadlight panel, making sure you brush it well into each and every segment so that the putty mix flows into & under the leads. Try to take your time to do a good job. When done, coat the panel with the extra whiting...no need to rub it in...just smear it over. Turn leadlight over carefully, and repeat the process. Once both sides are puttied, place the leadlight in a safe place ensuring air can get at both sides and leave for     1 HOUR...no more ...no less. When that is done, take a hard bristled brush ( something like a floor scrubbing brush ) and brush vigorously to brush away all the excess whiting and cement. Keep your brush flat so that you don't pull your putty back out of the lead channels. Using a wooden skewer run around each glass segment to separate the excess putty and brush again. Remember to also clean out the outside perimeter of you border lead, using a skewer and a brush. Now you can hold your leadlight on it's edge and using a variety of skewer, brush and banister brush clean up all the excess putty and dust remaining on the glass and lead. Take your time as anything left behind will set hard if left any longer.Apply a leadlight or stove polish and polish leadlight using an electric polisher if you have one or buff well with a soft polishing brush. YOUR LEADLIGHT IS READY TO INSTALL

WHEN DRAWING YOUR LEADLIGHT PATTERN, START BY DRAWING EITHER THE LEFT HAND SIDE OR THE RIGHT HAND SIDE OF THE DESIGN. ONCE IT IS AS YOU WOULD LIKE, FOLD YOUR DRAWING IN HALF AND COPY THE DRAWING ONTO THE OTHER SIDE USING A LIGHT BOX. THAT WAY YOUR DRAWING WILL BE PERFECTLY SYMMETRICAL.

A COMMON MISTAKE THE NOVICE LEADLIGHTER WILL MAKE WHEN DRAWING UP THE DESIGN, IS TO FORGET ABOUT THE CORRECT REINFORCING METHOD TO USE UNTIL THEY HAVE DRAWN THE WHOLE DESIGN. ESSENTIAL TO DRAWING UP A REINFORCED, STRONG AND STABLE LEADLIGHT IS   #1. DRAW THE BUILD SIZE FIRST.   #2. DRAW IN THE CORRECT REINFORCING LINES (IF UNSURE, CONFIRM WITH A PROFESSIONAL) AND THEN AND ONLY THEN......#3. DRAW YOUR DESIGN AROUND YOUR REINFORCING LINES. IF YOU LEAVE REINFORCING AS A LAST THOUGHT, CHANCES ARE YOU WILL CHOOSE TO IGNORE THE IDEA OF REINFORCING ALTOGETHER BECAUSE IT THEN INTERRUPTS YOUR DESIGN. THIS IS A DANGEROUS CHOICE. SO, WHEN REINFORCING AND STABILITY AND SAFETY OF YOUR LEADLIGHT DESIGN SHOULD BE YOUR FIRST PRIORITY, DRAW IN THE ESSENTIAL REINFORCING BEFORE ANY DESIGN ELEMENTS.  

If you are struggling with your design and not totally happy with it....tape it onto a wall or the fridge for a few days. Every time you go near it or pass it, stand back and look at it. It's amazing what you will see every time you look with new and fresh eyes. After a day or two, you should have ironed out all the "bugs".

THE DREADED GLUE CHIP !

just about everyone loves glue chip glass .... also known as crystal leaf...until they realise how it hangs onto the dirt and polish in the final stages of puttying and polishing.

whilst in the newly polished stage, you can clean the glue chip by spot cleaning the glass only with white vinegar on a cloth.

anything stubborn may have to be spot cleaned with turps. try to avoid getting your turps cloth on your lead, as you will have to polish all over again when it takes the black off .

The best way to avoid the whole glue chip problem is.........change your admiration of glue chip and choose something else !!

ALWAYS PURCHASE ENOUGH GLASS FOR THE JOB, ALLOWING FOR WASTAGE, AS SOME TYPES OF GLASS MAY BE EXPERIMENTAL RUNS OR DELETED WITHOUT NOTICE. CERTAIN COLOURS OF GLASS VARY FROM BATCH TO BATCH ALSO JUST LIKE DYE LOTS OF WOOL OR FABRIC. YOUR LEADLIGHT SUPPLIER MAY ALSO BE CLEARING OUT A SPECIAL THAT CANNOT BE REORDERED.

......ooooOOOOOoooo.......

 

IF USING SUCKERS WITH HOOKS TO HANG THE LIGHTER WEIGHT SUNCATCHERS..................

USE VEGETABLE OIL INSTEAD OF WATER TO STICK THEM ON YOUR WINDOW. LESS LIKELIHOOD OF EVAPORATION DURING SUMMER AND SUCKERS GIVING WAY AND DROPPING YOUR SUNCATCHER.

 

WHEN FITTING A LEADLIGHT INTO A DOOR OR WINDOW USE A BEAD OF SILICONE ONLY BEFORE THE WINDOW GOES IN AND NOT TO STICK THE BEADING BACK ONTO THE LEADLIGHT.  IF THE WINDOW EVER HAS TO COME OUT TO BE REPAIRED, BOTH THE BEADING AND HALF THE WINDOW WILL BE DESTROYED TRYING TO SEPARATE THE EXCESSIVE AMOUNT OF  SILICONE APPLIED IN THE FIRST PLACE. A CASE OF DEFINITE OVERKILL !

 

mirrors

ALWAYS seal mirror before using it in a leadlight or copper foiled project. You must seal both the mirror back and the cut edge to prevent moisture and corrosive fluxes causing the "dreaded" BLACK SPOT. Black Spot can show up later after you've gone to a great deal of trouble to create your masterpiece. SO...using a spray pack of a  polyurethane varnish, spray the back and cut sides whilst the mirror is face down on a sheet of newspaper. Hand puttying a leadlight mirror is also a good idea for the same reasons.

 

SAVE ALL YOUR

OPALESCENT SCRAPS

 FOR FUTURE

GLASS MOSAIC WORK

NEVER USE A U LEAD ON ANY LEADLIGHT FITTED INTO A REBATE. IF YOUR LEADLIGHT        GROWS  DUE TO INACCURATE CUTTING, YOU HAVE NOWHERE TO GO.  AT LEAST WITH A H LEAD YOU CAN CARVE SOME OFF WHERE NECESSARY. IT IS ALWAYS IMPORTANT TO HAVE THE WOODEN BEADING SITTING ON A CUSHION OF BORDER LEAD AND NOT ON GLASS AS WOULD BE THE CASE IF YOU USE A U LEAD.

CAR POLISH WILL CLEAN AND POLISH YOUR COPPERFOILED PROJECTS, HOWEVER THE SPECIAL POLISH  PRODUCED FOR THE PURPOSE  " Stained Glass Finishing Compound" DOES A FAR SUPERIOR JOB.  

 

ALWAYS ENSURE YOUR FLUX IS REMOVED FROM YOUR PROJECT, ESPECIALLY IF YOU WON'T COMPLETE IT IN ONE DAY. FLUX IS VERY ACIDIC AND IS BEST NOT LEFT ON YOUR WORK NOT EVEN OVERNIGHT. CLEAN UP WITH NEAT DETERGENT, A SOFT BRUSH AND SOME BICARB SPRINKLED ON TOP TO NEUTRALISE ALL.

FISHING SWIVELS ARE GREAT TO ATTACH TO SUNCATCHERS. THEY ALLOW THE SUNCATCHER TO SPIN IN THE BREEZE.

 

THERE IS A SIMPLE METHOD TO MAKE LOOPS TO HANG SUNCATCHERS FROM. GET A LENGTH IF COPPER OR TINNED WIRE, WIND IT ROUND AND ROUND A PENCIL OR SIMILAR OBJECT, FORMING A SPRING SHAPE. REMOVE THE "SPRING" AND WITH YOUR SIDECUTTERS, SNIP ALONG THE SIDE LENGTH OF THE SPRING. YOU WILL HAVE PERFECTLY FORMED LITTLE LOOPS.

IN THE PUTTYING PROCESS

When your leadlight panel has some really chunky textured glass (like sparkle), use a handful of sawdust thrown on top when  scrubbing with your hard brush. It will help clean off the excess putty that sticks to the textures.

 

LEAD HINTS

Learn about all the different lead sizes and vary their use through your leadlights. Bear in mind strength, and emphasis of design elements. Try not to get stuck on a particular favourite especially where a stronger lead is needed in a bigger panel. If in doubt, always ask a professional.

  Before you putty your leadlight coat your hands with BARRIER CREAM and you will find cleaning up easier.

ASK YOUR LEADLIGHT RETAILER FOR YOURS NOW

YOU MUST PUTTY & POLISH A LEADLIGHT REGARDLESS OF WHERE IT WILL GO AND THE NEED FOR WEATHERPROOFING. THIS IS AN ESSENTIAL STAGE AND CANNOT BE DISMISSED !  A CUSTOMER OF MINE CAME LOOKING FOR BLACK PATINA TO DARKEN THE LEADS OF A FULL LEADLIGHT ENTRY SHE HAD MADE AND FITTED WITHOUT PUTTYING ANY OF IT.  SHE WONDERED WHY THE LEADS WEREN'T DARK ENOUGH. WHEN INFORMED OF THE VITAL IMPORTANCE OF THE PUTTYING PROCESS SHE INSISTED THAT IT WAS ON A VERANDAH AND WOULDN'T GET WET. AFTER SOME HARD CONVINCING OF THE NEED FOR THE FINAL STAGE OF PUTTYING, SHE THEN ASKED COULD SHE NOT PUTTY IT IN SITU AS IT WAS WELL SILICONED IN BY NOW ! 

If you need twisted wire for special effects, try this method:-

Select a long length of tinned or copper wire (about 12 ft or so), fold it in half. Put the two separate ends in the chuck section of your electric drill and tighten. Put the remaining loop over a tightly fixed nail on your bench or on a fence. Press the trigger slowly and your twisted wire will form itself. Too fast and you will end up wrapped around your bench or fence !!! Stop when it is as twisted as you want. Release and cut into sections.
