Square, rectangular, hexagonal, matte, shiny. It's hard to think of a more versatile flooring material than tiles. They're also known for their high durability, ease of maintenance and installation, and are among the most common choices for covering floors and walls, whether wet or not. Following are 10 common questions about ceramic tiles, and their answers:

1. What is the difference between ceramic and porcelain?
The fundamental difference between ceramic tile and porcelain tile lies in the technology behind their production. Porcelain is the result of a more controlled manufacturing process than ordinary ceramics, made through a mixture of porcelain and various minerals burned at over degrees Celsius. The resulting material is more homogeneous, dense, vitrified, and resistant than conventional ceramics. It is also less porous and therefore has a very low water absorption index, making it more durable as well. This feature makes it suitable for high traffic locations such as airports or shopping malls. Porcelain glazes are also known for their greater color variation, providing a rich custom look.
Ceramic, in turn, is composed of a mixture of clay and some minerals. Due to the slight variations and irregularities, it may yield a more interesting aesthetic result.
2. What types of finishes exist?
The finish refers to the upper surface of the tile's coating and can be polished, shiny, satin, matte, or natural.
3. Is ceramic tile a durable material?
Yes, but this depends heavily on the installation. To optimize durability, the subfloor or base on which the tiling will be glued must be flat, stable, and without irregularities. Depending on the dimensions of each tile, the proper mortar must be used. For larger pieces, manufacturers recommend double gluing on the subfloor and the back of the tile. Generally, carefully following the manufacturers' recommendations is always the best thing to do.
4. What is a rectified tile?
Rectified tiles go through a cutting process called grinding, which trims all pieces to the same exact size. As a result, seating joints can be minimal, reducing the amount of grout and making the assembly more aesthetically pleasing.
5. How do I calculate the number of tiles I need?
Of course, you will need to know the area of the space. But you should also plan to start with more than the exact number of tiles that will fill the area, due to breaks and cutouts. Generally, adding 5 to 7% in surplus to account for cut loss is sufficient if the environment is simple (square or rectangular with few cutouts). If the plan is diagonal or if the environment has a distinctive or organic shape, then many pieces will have to be cut at the corners. In these scenarios, it is important to provide a surplus of up to 15% to avoid material deficit during installation.
6. Can floor tiles be installed on walls? Or wall tiles on floors?
Virtually any floor tile can be installed on the wall, though in most cases, it is not appropriate to switch them. Consult the installer or product manufacturer for application recommendations.
7. Can I install tiles on top of other tiles?
Usually, yes, but only if the surface below has been installed correctly and is not broken or experiencing any problems, such as stuffing. However, this is generally not the smartest option, and though initially cost-saving may later incur higher costs. Keep in mind that overlapping floors will slightly decrease the height of the room, and that the doors will have to be altered to open normally.
8. Are ceramic tiles non-slip?
To know whether or not a tile is non-slip, it is important to know its dynamic friction coefficient, which is an index of slip resistance. The higher the number, the more 'non-slip' the piece. Each country has its own norm in this regard. In Brazil, for example, manufacturers follow the Brazilian standard of /97, which divides parts into two classes:
-
Class I - Coefficient less than 0.4 - Indoor areas only;
Class II - Coefficient greater than or equal to 0.4 - Can be used outdoors and are safer for shower stalls, for example.
9. How do you cut and pierce tiles?
For straight cuts, a special tool is generally used that scratches and then cuts the tile, creating a clean cut and good finish. For other details or clippings, a disk saw can be used. It is important to use the proper disc for a satisfactory finish on the tile. To create holes, the ideal method is to hire a specialized technical team to avoid cracking.
10. Is it possible to paint on tiles?

Transcript
You are listening to episode 8 of the MudTalk Podcast. This episode is a little different from other episodes so far. It will be a little shorter than normal but I think it will lead to a lot of discussions in the future. For this topic, I left it up to you to ask the questions. I wanted to know what you would ask other potters or ceramic artists. I thought it would be a great way to get some ideas for future MudTalk Mondays and make sure we&#;re discussing topics that you REALLY want to discuss.
There were a lot of great responses. Everything from, &#;how do I get started?&#; all the way to &#;how do I price my pots and make a living?&#; As usual, when I was reading through the comments some patterns started to emerge. So we are going to start with the beginner questions and then hear some of the more technical questions. After that, we&#;ll look at some of the questions about the business side of working with clay and then we&#;ll hear a few miscellaneous questions. At the end I&#;ll give a preview of upcoming MudTalk topics so you can send in a message that could be on a future podcast or get a response ready for the MudTalk Monday social media posts.
So let&#;s hear some questions that you would love to ask other potters or ceramic artists.
Beginners
There were a few people that just wanted to know how to get started.
Monstriss As someone who only did grade eight art and did a semester in Pottery, where do I start with literally nothing?
Shshshelby I&#;m so interested and have nothing to start with &#; where do I begin and with what kind of products?
I&#;ll give a brief answer here because I love when people try something new, especially if it&#;s working with clay. One thing I love about making pottery is that you can start small. All you really need to get started is clay. As you progress you can start adding tools and equipment and try new techniques. The complicated part comes when you are ready to fire and glaze your work. For a longer, in depth answer, I have a new course coming out soon at Expert Clay for complete beginners that want to know how to get started.
Technical Questions
There were a number of technical questions about specific parts of the process.

Theclayrabbit Great idea this thread! I would LOVE to find information on COLD FINISHES FOR SCULPTURES because I&#;ve tried looking for books on it and online for this topic and there&#;s nothing much out there &#; and I&#;m always searching for lovely MATT finishes firing and non firing with methods of application that are user friendly ?
_shandiReynolds_ What&#;s the best way to pull up walls? I can pull them up to an extent but I can&#;t seem to get it
Jane N what brushes does one use when they want to draw figures onto bisque fired pots. I never seem to get the correct brush size or type and my strokes just come out looking yucky and not what I want
Business
There were also a number of questions about selling pottery and running a business.

Ladytokioblue Also how do you keep from getting hand or wrist pain from repetitive motion?
Anita M How do you feel about sharing glaze recipes? Do you think it&#;s important to share and possibly allow others build on your work to further everyone&#;s knowledge base or is it better to not share and encourage them to learn how to get to that stage and build upon their own discoveries? How important is recipe sharing in our field?
And finally,
Michelle W How do you organize your work week? Do you have specific throwing days? Glazing days? Or does it change from week to week? I would love to (be) able to know how to organize my schedule so with festival, market, and commission pieces all running I don&#;t get backed up and have to work super late nights for a week straight&#; Any tips on time management??
