Bringing a well preserved antique fireplace back to perfection - part 2

In this follow-up post I was going to show you the carving process from start to finish. Unfortunately I had a devastating hard drive failure and my back-up was mostly corrupted, so I lost some of the layout photos. You can find the process in some past posts - like here -

I did make a short video of carving - it looks as though I'm in fast motion, but it was real time....I guess I was in a hurry to make it a short video!

It was a great first pouring of the plaster. Unhappily, all the photos of pressing the tile, bisque tiles, and glazing are lost. But I am waiting for the completed installation shots from the customer and I'll post those when I am able.

Thanks so much for reading and please contact me directly at lestile@nycap.rr.com if you have any questions, or if you have a tile that you would like reproduced or custom carved.

Bringing a well preserved antique fireplace back to perfection!

We create many fireplaces using our large inventory of moulds that have been created to reproduce antique tiles. New design are being added constantly, due to the many requests we have to help customers bring their antique fireplace back to it's original splendor. Following is a current project that highlights the steps that we take to "make it so".

Inquiries begin with either an e-mail through our website,  L'esperance Tile Works, or a phone conversation requesting information and pricing. If the pattern that needs to be reproduced isn't already in our catalogue, then we'll need a really good photograph with a straight on perspective, or most preferably, an actual tile. Cost ranges from $500.00 - $1200.00 to create a reproduction, depending on the depth of caving and intricacy of the pattern.

The reproduction that I'll highlight in this and the following posts, is a tile originally from the JG Low Art Tile Company, border # X23 on page 4. The fireplace in question needed only a few pieces of the border, but the process is the same whether it's a few pieces, or a full fireplace border.

The fireplace is situated in a bedroom in a condo in Portland, Maine.

All tiles are original from the JGLow Art Tile company, circa 1904.

   

Amazing how well preserved this gorgeous fireplace is!

The customer sent us some closeup photos of the tiles, along with a small fragment of one of the originals that had broken. The mission was to recreate the tile and match the glaze.

This photo is a clear, straight on view of the border tiles.

Original tile fragment

To match the glaze as closely as possible an original tile is needed. Images sent via e-mail or from the web aren't true enough due to the variations in monitors and camera settings.

Glaze library with some blues

After I receive the original tile I go to my glaze library which has accumulated tests over the last 35 years! I can usually find a very close match from there, however, that is just the starting point. I'll mix 2-3 small batches of the glaze formulas and test them on some decorative and field tiles - usually seconds that are warped or cracked. After confirming that the recipe is still in the range, I'll then mix a batch large enough to glaze the entire order. That batch also gets tested, and altered if need be.

Two of the closest glazes mixed

I'll then send my closest matches to the customer for approval. In this case I had 2 that were very close, but sometimes the tone of the glaze will change when set next to the originals on site. Since the glaze match usually happens while the carving is in process, I'll use another border to show how the glaze will sit on the details. My glaze flows away from the high points and settles darker in the recessed areas - very similar to the glazes I'm attempting to match.

We got and overwhelming approval of glaze "B" - the one on the bottom.

I'll show the carving process in the next post,  so stay tuned!

Thanks so much and please contact me directly at lestile@nycap.rr.com if you have any questions about the process, or if you have a tile you would like reproduced.

My Tile reproduction....Part 7

How do I make my plaster moulds? Honestly.....not with a lot of enthusiasm.

Plaster is not my favorite material to work with....in fact plaster and I don't really enjoy each other very much. If I can, I let someone else make my moulds for me, but that's usually for large production runs. If I only need a few tiles for custom orders, then I just suck it up, get the apron and gloves on, and mix it up.

I set my wax on a thick pane of glass, which gives me a level surface to pour the plaster on.

I brush a thin coat of vegetable oil onto the wax to help the plaster separate from it.

I use plastic slats to create the frame that the plaster will be poured into. I seal the edges with soft clay.

Mixing the plaster. I use the intuitive method of mixing the plaster into the water - add the dry plaster to the water until it makes dry islands just above the level of the water. Then I let it slake for a few minutes and stir for 8-10, while impatiently waiting for the perfect moment to pour.

I overfill the frame and let the plaster stiffen while I clean up the mixing bucket and messy spills.

When the plaster just begins to harden I use another plastic slat to level the it to the top edge. This ensures a consistent thickness and level to the mould.

Surface and edges are clean and now I just have to wait for the plaster to finish setting up. I take care not to go far because I've found that the plaster can get hot enough to warp the wax. I release it when it's hot to the touch.

A lovely sight is a just released plaster that has NO bubbles and every detail is in perfect form. This one turned out great.

Now that I have a working mould, I'll let it dry for a day or two and then...onto pressing the tiles!

Part 3 of Reproducing a Victorian Tile.

Ok - I've got the original tile, or at least a photo of what needs to be carved. I've formatted the image to a larger size to compensate for the shrinkage of the clay body. Now I need the materials for creating a reproduction of the tile. There are many different materials that can be used to create the master tile that moulds will be made from. Some include clay, plasticine, plaster, beeswax, jeweler's wax.....I prefer "holy wax".

My Mom helps clean her church - St. Augustine's in Lansingburgh, NY - and has been saving the candle discards for me for 30 years now.

I have many, many, many boxes of candles of all shapes and sizes - but a LOT of these  partially used vigil tapers.

I use this great old electric pot to melt my wax in, and set it at about 200* F to melt the wax. There's always some "starter" wax in the bottom left over from the last pour.

I add more candles to fill the pot up about 1/2 way full. It's about a quart of wax altogether.

I use a wooden kabob stick to stir the wax - everything melts together in about 10 minutes.

At this point I usually add a red candle to color the diluted wax. It took me about a year to decide what color I liked to carve the best. A light "emberglow" seems to be the easiest and most soothing on my eyes. I used to carve a light tone of lavender, but the wax moved itself towards more honeysuckle tones all by itself, and I let it go where it wanted to. I did discover early on that blue and green didn't work for me at all. And - never, ever, ever, add scented candles to the mix - big mistake.

When the wax is just about all melted I add stearic acid - about 1/2 cup to 1 quart of wax - but try it out for yourself to find the mix you like. It makes for a harder, more durable wax (but it won't save the wax from melting in the mid-day sun...so if your head is made of it, watch out.....inside joke for my dear husband). Also - if you leave your wax carving on the dashboard of your car - it WILL melt.

Pulling out the wicks from the melted candles.

I pour my wax, and have been for 30 odd years - into this enameled pan. It has a very smooth surface and is easy to level when I pour the wax into it. I heat it up over the hot wax for 3-4 minutes, so that when I pour the wax into the pan it melts smoothly onto the surface rather than cooling immediately and leaving pouring marks. Learned that one the hard way.

I lay the pan onto paper or cardboard, which helps to insulate it from cooling too quickly.

I unplug the electric pot and slowly pour the wax into the pan.

The wax is transparent until it begins to cool. At this point I level the pan out with folded pieces of paper. The black line around the pan has always served as a great leveling line.

I usually let the wax sit overnight to cool. It becomes opaque as it cools, and pulls away from the pan slightly. If I want to carve the same day, I'll put the pan with the somewhat solidified wax into the refrigerator or freezer. Cooling the wax quickly creates a very interesting textured look and feel to the back surface, but I prefer a nice smooth back. I always carve from the front - or the surface that has been against the enameled pan.

The wax just pops right out of the pan.

Almost as good as a large slab of dark chocolate...this baby is ready to be carved upon!

So - there you have it. Now that you know how to prepare a slab of wax for carving..what are you waiting for? Send me photos of your wax slab and what you're working on, I'd love to see!

Next up - I might have to add a bit of somewhat related art history here...or maybe I'll just jump right into the thick of it with the tools I use and how I start the art.

Stay tuned!

Reproducing a fireplace tile - part 2 - formatting the image

As I walk you through the process of reproducing a Victorian tile, I'll try not to leave any of the steps out - which I'm finding is actually hard for me since I zip through the first steps without much thought!

Scanning the tiles.

After cleaning the tile to see the details, I scan the tile to Photoshop, where I need to  increase the size of the image by the amount that the clay will shrink after glaze firing. Our clay body shrinks 10%, so that's what I increase the image by. Then I print the image out to use as a starting guide for my wax carving.

Scanned image increased in size by 10%.

I've also cut and pasted the image at the bottom as a guide for making corners. Since the clients didn't have any corners in their original fireplace set, and I can't find an image of the original tiles anywhere, I'll be designing them myself. It always adds a nice detail to have the design wrap the edges.

At the carving table with image and original tiles.

At this point I get to head over to my carving area - my most creative and challenging spot in the whole building. As I look at the photo and the original tile, my brain begins to tell my hand how to carve it......no, not that way, this way....watch out, not too deep, make it a smoother line....

Wow, I'm glad that internal dialogue doesn't really exist!

The 10% shrinkage that I'm compensating for.

So now that the formatting is all done.....I need a nice clean piece of wax to carve the design into. Join me tomorrow when we visit with Madame Tussaud and get the secrets of making great wax!
