name's Richard Snyder I'm the owner and operator of one glass impressions clean master sinks I'm a custom window designer and builder for residential and commercial and I'm always in the process of developing and inventing new tools for the trade for hobbyists to professionals this is a new product I'm introducing to replace a product that has been selling on the market for many years that if you use it will pretty much damage and cause a problem to your beautiful artwork it's a product called patina for zinc that is sold under many names in the market but the problem is is that if you use it it will pit and cause problems watch the the metal as you can see in this example window how it's pitted and watched the zinc it is fixable with my new product called stays black patina for zinc I am the sole distributor of this product and it is non hazardous to use although it is considered a light acid and it's recommended to use rubber gloves that instead of the process of wiping instead you dip using my product and you get a results that is unmatchable to anything that's out there guaranteed to work and it will turn your zinc jet black and in the next step we'll show how the proper use to use this new product the things that come with this product also our scrubby pads because you need to scrub a the the zinc on the front the back and the edge all the way around your window or product that will scuff up the metal and make a nice clean surface oil free from fingers or from flocks of soldering it should be solid we cleaned up and free of any dirt it comes with a sheet material safety data that explains the breakdown of the chemicals and you can view it now it's also rated by the d-o-t as being non hazardous for shipping purposes which is a good thing and also the fact that it is not a cancer-causing chemical this is a comparison of the patina that is sold out there nationwide right now that has a problem with the not working and will cause problems to your zinc if you use it being unmatchable to your regular patina for lead or solder compared to the new product treatment of stays black my new product that is a window here that has been treated the same zinc being treated as far as dipping and you can tell that it is a totally jet black that matches the lead compared to the patina that watches the zinc and causes major problem this step we're going to clean up the zinc on this example window for the preparation of applying and dipping this the window into the stays black this product stays black patina for zinc is for dipping I know that the different patina is out there you use it by wiping that is the the change with this new product is that you dip the zinc edge into the solution into the patina and hold it for 40 seconds and we will show that step-by-step how that works at first though we have to prepare the zinc and by that I mean we have to remove all the oil from handling from fingers or the flux to make sure that it's totally clean and first we'll get into to is that since the stays black patina is considered a mild acid we will be using rubber gloves to refer protection over hands and skin and also any surface that you are working on countertops or other than a bench that it doesn't matter you should cover the top with some kind of a covering cardboard I have on top of this bench just for that protection now we will use a scrubby pad it's a basic kitchen type fiberglass scrubby pad you never use any type of steel wool or metal wool because of the oxidization of the patina would cause problems with that you want to use a plastic scrubby pad and they come with the product we go over all edges by cleaning the surface and make sure you do a thorough you want to sign that off go over all your solder and let seems there it's not a problem the stays black will probably splash up onto those areas which will also turn jet black we go over the whole surface the edging and this is a very important step you want to make sure that that zinc edge is shiny and clean of all oil and dirt I just go over it very thoroughly through the whole front edge it's signs it right up you can move your scrubby around if it wear out wears out in one area turns around make sure you got the back edge done you can't do this too much it has to be done very thorough it is the key to a even jet black finish okay that should be sufficient okay now I take a dipping tray i have custom dipping trays I have to stock designs that I manufacture and sell on my website one is the 25 inch long and one is the 37 long and then I make custom they're made from the same material that I make my clean master sinks out of called polypropylene that will last a lifetime abuse some of them come with with a shutoff valve in a holes that you can drain it when you're finished other than picking it up and pouring it out or you can just keep them keep the patina in if you have students and and teach this one here is for the hobbyist this is a stock item plastic you can buy it anywhere at a Home Improvement Center it's mainly for drywall mud if you're a drywall ER or I believe they come stainless steel too but this is fairly inexpensive one you can use many times four or five bucks what we want to do now is put on our rubber gloves lay your window down and it is considered a light acid and anybody with sensitive skin you definitely want the rubber gloves the stays black patina it's got a lock top childproof and you want to pour in enough that when you splash you want to splash the patina up into the zinc on the inside between the glass you can pour I pour about a half inch or so into the bottom this is a four ounce bottle you can pour the whole bottle in there and another great feature of my product stays black patina is that it can be route reused up to three times so after we use this I usually mark on the bottle the date and the time I used it and we can pour it back in the bottle and use it two more times take the window here and we're going to set it in the solution and we're going to move it back and forth and count 40 seconds it takes that much time to oxidize that zinc the chemical reaction with my product stays black patina and as you can see it's turning jet black right before your eyes okay that's about 40 seconds okay now we're going to flip it as you can see it's jet-black it splashed up onto the the lead cane that I used in the solder joint and I turned that jet black as well okay another 40 seconds okay that's 40 seconds we're going to turn it as you can see a perfect match as the first side another 40 seconds okay one more and another 40 seconds okay at this point there is a few more steps that we're going to do so we'll go on to that this step we're going to apply the regular patina that they sell out on the market for lead came this example window that we just applied by dipping into the stays black patina the edge now we're going to apply the regular patina that you wipe on for the lead canes and we just do that like you normally would and you apply it to your lead turn that black to match everything here sometimes I find too that if you're doing a large window panel that the rag gets pretty dirty from using especially with black patina that I switch rags because they get full of the blackness and it works better if you have clean rags to reapply the patina you know we're gonna flip this over into the back side this is a tray that I use other than using a sink you want to use something of course waterproof because after this step of applying the regular patina to the lead came or the solder if you used a copper foil technique is washing a cold water only okay now we're going to wash it in cold water consult it make sure there's plenty of bottom I never use soap it's just plain cold water and just let it soak you can flip it over get the other side make sure as well as you can see the the states black patina dent watch it if you would have used the patina out there for the zinc that does not work your zinc would be all blotched and as soon as water hits it it becomes unblocked and from that point on the only thing you can do is either paint it black or cover it with a wood frame because it takes away from your art project at this point we will take it out of the water set it on edge dry it and let it drain out because the next step we will apply our wax and now we have a new finish that is connected with the stays black patina for the zinc which is called Lac extreme and it's for the zinc channel only that we just patinaed with stays black it's salt resistant and it'll last for many many years and you can apply the regular polish for your ladder your solder and glass as well to preserve the beautiful color and the lead or the solder joints so it all matches totally at this point one other point that I should bring to attention that sometimes in this process if it doesn't turn totally black the zinc it'll turn kind of a dark brown bronze don't be alarmed because as soon as you dry your project and go to apply your wax it'll turn a jet black right before your eyes and it's jet black for years to come this step we're going to finish the panel by using two different types of waxes we've done the the patina the last step we did the patina for the lead using the basic that's out there and that works for ladder solder and before that we did the dipping of the stays black patina for zinc by dipping the panel into the solution and holding for 40 seconds on each side of your panel which turns it jet-black at this point we washed it in cold water only dried it thoroughly that's one of the most important things as well as to make sure your panel is dry tip it on edge if you can safely and let it drain out and then pat dry it with the soft cloth at this point we're going to apply a basic wax liquid wax that I use sold by clarity very normal while you buy it any stained glass supplier a very good product I've used for many years liquid wax that make sure you shake it up and and we'll apply it here with the soft cloth and we're gonna do the inside first of the lead lines or if you use the copper foil technique the solder lines let's shake it up here a little and we just go over the glass and all the solder of the lead and of course with any wax you let it haze over to say no not the sink just the lid and if you were going to do the whole window off you would want to raise this up off the back to let the air get under it to dry it thoroughly so we'll just let that set to haze over at this point we can use the new product called stays black lack extreme it is a liquid again special polish it's for the zinc and we brushed that on and it comes in three sizes it comes in a four ounce bottle it comes in a two ounce bottle and a one ounce bottle and they're sold on my website the same with the stays black patina for zinc and that comes in three sizes four sizes now a quart the 16 ounce 8 ounce and four outs the slack extreme is a water base non hazardous and very easy to use and like I say you apply that it's a coating that you actually it comes with a little brush too that you can use over and over by just washing it out with water when you're finished and if you of course we're going to do the back side as well in one step you'd want to raise this panel off of your surface because it takes a while to dry minutes but it could stick to the surface and create a problem and you just want to brush that over and the edge you'd want to do too and that will protect that finish for years to come it's even salt resistant salt water resistant and I know from experience that using the the liquid regular wax that in time possibly a year later you'd have to re reapply your wax to your seams of ladder cop LED or solder joints because it will faint just from oxidizing and normal air but with the lack extreme for stays black it'll last for many many years to come it actually coats the zinc and holds the coloring and you just want to brush that make sure it the jet blackness it just stays nice and jet-black like no other finish out there and of course if we raise this up we could do the edge so it don't stick to your surface and you could even flip it over and do the other edge and that will preserve that color for many years to come like no other finish out there you may have to redo the the center of its ladder solder with a normal because it will fade you could possibly use the lack extreme for all your LED or solder joints depending how intricate your seams are but you would have to go over with the razor blade to get off the excess and it would preserve that as well and that's basically the finished process of using the new product to a lack extreme for stays black patina zank sold exclusively at one glass impressions calm another fine incredible product for the stained glass industry and as you can see a jet black finish like no other
