Eastern Screech Owl Mosaic by artist Linda Lawton

Owl Mosaics and The Importance of Andamento

Linda Lawton emailed me some pics of her recent owl mosaics, and one of them had an issue that made it a good teaching example about the importance of andamento. That mosaic also became a case study for how to mosaic on top of part of an existing mosaic if you want to rework a detail.

Since Linda is serious about her art and is always working to improve it, I felt like I could be honest with her in a way I couldn’t when critiquing the artwork of “someone I didn’t know.”

Over the past few years, Linda had emailed me about several different mosaics where she had ripped up tiles and re-executed details she wasn’t happy with. Some people have the true artist’s obsession with art and making it better, and it shows no matter the age or skill level.

Shipping Resumed

We have resumed operations and are now shipping packages normally.

Please be decent to people in these hard times.

APOLOGY AND CONFESSION

My apologies to anyone who I have offended with my criticism of Donald Trump in my previous post Coronavirus Helmets, but you might want to give me a pass on that for several reasons:

My ex-wife is from NYC, and I was aware of all the deeply disturbing things that local people knew about Donald Trump BEFORE he entered politics, including assessments by very conservative bankers and tradesmen who hated Hillary Clinton with a passion. Most anyone who worked with Trump described him as a crook and cheat with too many ties to the wrong sort of Russians.

I have other insider information that makes me feel guilty for not speaking out sooner.

Coronavirus Helmets

My son and I took a short break from planting our native and heirloom vegetable garden and digging a second tadpole pond and made Coronavirus Helmets, which are an essential piece of equipment these days. The Coronavirus Helmet featured in this post is mine. I have more about Henry’s helmet later in this post.

As I write, there is almost as much proof that these helmets repel Coronavirus as there is proof that malaria meds work for Coronavirus -at least not any better than any number of existing pharmaceuticals that were designed for viruses and not a protozoa like malaria.

That is why I feel like I have contributed as much in the fight against the pandemic as Donald Trump has.

More actually. I spent much of February warning friends and relatives of the coming catastrophe and encouraging them to buy groceries and make other preparations as soon as possible.

What did the President do in February? He repeatedly claimed everything was under control and played golf.

My apologies to anyone who is offended by that comment, but you might want to give me a pass for several reasons:

My ex-wife is from NYC, and I was aware of all the deeply disturbing things that local people knew about Trump BEFORE he entered politics, including assessments by deeply conservative bankers and tradesmen who hated Hillary Clinton with a passion. Most anyone who worked with Trump described him as a crook and cheat with too many ties to the wrong sort of Russians.

Like any experienced manufacturing engineer, I had a complete safety plan for my employees to work solo shifts wearing N95 masks I purchased well in advance of the crisis, having dealt with outbreaks of flu and stomach virus in production lines before. My criticism of Donald Trump’s lack of a timely response is from professional experience.

The mosaic business is merely one of my activities, and I spent the past year looking into developing an aptameric alternative to protein-based drugs such as Humira. My masters thesis involved microbiology and the University of Georgia patented it.

How does a guy who has 8 part-time employees outperform the President of the United States? And how did I do it when my decisions were only based on basic information accessible to anyone who follows international news?

I don’t often use words like doddamn and futhermucker when I speak to my momma on the phone, but I did when I called her and explained why she needed to stop watching Fox News.

Warning: Marine Plywood Not For Mosaic

Marine plywood cannot be used as a mosaic backer for outdoor and wet mosaic.

Yes, marine plywood can withstand the outdoors and wet days for many years, but it is completely unacceptable as a mosaic backer because it swells and contracts with changes in humidity in the outside air. That amount of swelling and contracting is tiny and might not be significant in construction projects, but it is fatal for mosaic. Absolutely fatal. It’s only a matter of time, and it’s usually not long.

People recommending the use of marine plywood as a backer for outdoor mosaics are not considering one critical detail:

The swelling and contracting of wood due to humidity isn’t trivial where adhesives are concerned, and the displacement (movement) can be measured. Imagine rainy days versus dry days. The displacement is more than enough to work glass free from adhesive because the glass isn’t swelling or contracting at all.

This is not speculation. I am an engineer and have worked in a materials testing lab.

Another piece of evidence I could bring to any argument about the use of marine plywood in mosaic is that I have received photos of tragically-damaged mosaics for 17 years, and marine plywood wins hands down as far as being the worst cause of grief, and the reason is simple:

Marine plywood SEEMS like a solid safe option because contractors will talk about the life they have gotten from it on certain jobs, and so the people who make the mistake of choosing it tend to be people who are making a design with a lot of work and care for the details. They took the time to choose a “good” backer because they knew they were going to put a lot of effort into their mosaic.

Seeing these mosaics damaged is much more painful than seeing some hasty work falling apart because the technical details were just outright neglected.

That brings me to an email I received from Monika Walter.

Artist Monika Walter

Monika Walter says she doesn’t consider herself to be an “artist,” but she has some solid work at her mosaic website, and she makes tables and mirrors and clocks for craft shows. They all look well-executed to me, and a couple of her mosaics make me jealous. More about that later.

Well-Executed First-Time Mosaic

One of the most well-executed mosaics I have ever seen in terms fine details wrought in slivers of glass came to me in photos in an email last week from artist Irene Clifford.

As Natalija pointed out, ” Most people would throw away tiny pieces like that as scraps.”

The mosaic is excellent work in several ways.

The andamento of the mosaic as a whole is instinctive, and it fits the details and curves being rendered naturally (instead of being rows to cover space without much regard for the shape of the color field).

The size of details relative to tile size is optimal for creating visual interest. That and the andamento impress me more than the exceptionally well-executed details with glass slivers.

Most people could make multiple mosaics without ever coming close to this level of instinctive andamento or being able to work with tesserae that small, being more or less a sliver.

Centering Mosaic Table Top Designs

Artist Stephanie Potter‘s mosaic table top designs are mandalas that catch and hold the eye with contrast, symmetry, and visual interest. They are centered so that the outer circle of tile is at the edge of the circular table tops.

Mosaics made on wooden table tops are for indoor use. Outdoors, the wood swells and contracts with changes in humidity, and that causes tiles to pop off.

Of course, it is easy to explain how you keep a design centered if you draw out all the work lines for the rows of tile, which would be more or less required for such detailed, symmetrical designs like these made by Stephanie.

But how do you center a mosaic on a round table if your pattern doesn’t show every row of tile? What do you do when you want to improvise a figure in the center of a table but still surround it with concentric rings of tiles where the outermost ring of tile is at the edge of the table?

When To Use Sanded Grout

This article is about why we recommend “the opposite” of what the tile industry recommends for grouting glass mosaics and mosaics with a standard grout gap. This article also explains how to avoid scratching the glass tile while grouting with sanded grout.

Industry Recommendations

The tile industry recommends using sanded grout for gaps 1/8 to 3/8 inch and adding a coarser grade of sand for gaps larger than 3/8 inch. For gaps less than 1/8 inch, which is what mosaic glass mosaics have, tile manufacturers and industry associations recommend using non-sanded grout.

At Mosaic Art Supply, I have always recommended using sanded grout for everything except mosaics with hairline gaps between the tile. Why the difference? There are three reasons.

Plaques not Walls

Many of our customers are making mosaics on small movable surfaces like plaques or tabletops not walls or floors, and these smaller mosaics are subject to being dropped and impacted and vibrated and flexed more than an architectural surface. The sand provides tensile strength and helps the grout not be knocked out of the gaps as easily.

Geometric Architectural Perspectives

Recently I wrote about The Stylistic Range of Mosaic Art and mentioned that I am still being surprised by the different styles that artists are able to execute in the medium, especially those with formal training.

I meant formal training in art when I first wrote that, and I was thinking about how technical innovation is easier for someone who has studied the nuts and bolts of different mediums.

Later I got to thinking about the extent to which art is fertilized by study of other disciplines, and not just the example of how Renaissance artists studied mathematical perspective and anatomy.

Mosaic Mural Backsplash Epic by artist Yulia Hanansen

The Stylistic Range of Mosaic Art

At Mosaic Art Supply, we have always tried to promote contemporary mosaic as a fine art and help people of every skill level create original work instead of selling overpriced craft kits for making cliche designs. This may have hurt us some financially, but I have never regretted taking the high moral ground. After all, if I wanted to help people mass produce junk, I could have remained an engineer in the corporate world.

One of the things that I have found particularly rewarding is seeing great art made by ordinary people with no formal training in art. I have also enjoyed seeing the range of styles that professional artists have been able to execute in mosaic, proving that the medium is as versatile as oil painting, perhaps even more so because of the found object and textural elements that mosaic can incorporate.

Recently one of my employees showed me the work of artist Yulia Hanansen, and I was intrigued for several reasons, and not merely because of the stylistic range of her work, which is impressive in itself.

It would be difficult for me to say which piece is my favorite, but I particularly like the kitchen backsplash with the paleolithic cave painting images from the epic period of human prehistory known as “The Great Hunt.” I like how its cool cyan color scheme complements the warm wood cabinets. It is not only an interesting and original mosaic. It is also a well-integrated part of the room’s interior design.

Public Art and Commissioned Mosaics

Artist Steven “Stevo” Sadvary has a broad mosaic portfolio of pet portraits, cityscapes, signage, educational murals and other public art, all solidly rendered.

I like public art that inspires people to make their own art, especially children, and I think there are a few things about Stevo’s art that make it optimal in that way.
