(for the book ask) 6, 10, 24? -vm
Hii! Thank you for the ask!
6. Was there anything you ment to read but didnt get to?
Absolutly! I somehow keep buying more books than I finish haha. One book I've been meaning to read for a while is 'le petit prince' but I havnt because it's in French and I'm not that good at french( I bought it to get better but yk)
10. What was your favorite new release this year?
I havnt read anything released this year to be honest but from what I've heard 'the sun and the star' was really good.
24. Did you DNF anything? Why?
I started but never finished 'Loveless' because at the time I was more excited to read another book I bought and also because a friend of mine said they didnt really like it so I've been a bit discouraged from reading it.

Ceramic Clay: Tips for Choosing the Right Grade and Texture
Understanding clay is one of the most important aspects of pottery making. Knowing what different types of clay are, their properties and how they respond to different firing temperatures will help you create successful pieces of art.
Ceramics are all around us. They are used in things like tile, bricks and plates. They can be molded into functional pieces of art, such as jars and pots or shaped using wheel throwing techniques.
Grade
The type of clay you use can make a difference in the properties that your finished ceramics will have. There are many different clays, including red clay, white clay, kaolin, porcelain, stoneware and others. Each one can be used for different purposes and has different properties. The clay's grade determines how much it shrinks during firing and whether it has other qualities that affect its overall performance in a specific application.
Pottery is a broad term that covers any item made from clay, but it's most often used to refer to functional items such as a coffee mug or ceramic vase. Pottery also includes decorative and art pieces. It is usually created using a pottery wheel, where a lump of wet clay is clumped onto the spinning wheel and shaped into the desired form with a variety of tools and then left to dry.
The ceramic clay used for pottery may be mixed with other materials to improve its performance and durability. These additives are known as grog, sand, sawdust or other material added to the clay while it's still wet. Studies show that a high percentage of ionic bonding and low percent of covalent bonding in the clay's compounds contribute to a ceramic with superior strength and heat resistance. These characteristics may be improved further by incorporating soapstone waste as an additive to the clay.
Texture
The clay particles that make up ceramics are called platelets. During firing, these platelets move closer together and bond to each other, filling in the spaces between them to create a strong and dense clay body. This process is known as vitrification. Different types of clay body have varying degrees of vitrification, so it's important to know which one you're working with when making your art.
When kiln-firing ceramics, the clay is placed on a refractory shelf or post that's designed for the specific type of clay. This clay "furniture" helps the ceramic ware retain its shape during the kiln's high-temperature firing. Once the piece has been shaped and dried, it's coated in decorative, paint-like glazes. The glazes are then fired again to harden the material.
Whether it's used for coffee mugs, serving dishes or intricate sculptures, pottery and ceramics have been an integral part of human culture for thousands of years. These beautiful and functional artistic expressions can even improve a person's mood.
However, pulling clay straight out of the ground isn't exactly the cleanest process. There are a lot of different things intermingling down there, like iron, dirt, rocks and other goodies that can affect the final quality of the clay. So, when you're creating your ceramic masterpieces, it is often best to use a pre-made mixture of clay instead of trying to pull pure clay from the ground.
Firing Temperature
The clays used for ceramic are kiln fired in a high temperature oven known as a kiln. The resulting ceramic pieces are often covered with decorative, paint-like substances known as glazes. The type of glaze a ceramic is covered with can greatly influence the final piece's appearance. The color and texture of a glaze is determined by its ingredients, which include silica, fluxes and metal oxides.
The firing temperature of a clay has an important impact on its properties and is critical to the success of ceramic manufacturing. For example, ceramics made with a low-fire clay that has not been heated to the proper temperature will crumble and dissolve when they are put in water. However, ceramics that have been fired to the right temperature will be hard and durable.
When a clay is fired to the correct temperature, a process called vitrification takes place. During this process, the proportion of glassy bond increases and the porosity decreases. Additionally, mullite (aluminum silicate) crystals form in the clay and act as binders, strengthening it even further.
The firing temperature of a clay can also have an impact on its color. For instance, some low-fire clays contain a large amount of iron impurities which will react with oxygen and other elements in the kiln atmosphere during firing to produce unique colors and textures. The color of these clays can range from brown and earthy to gray and bluish depending on the temperature at which they are fired.
Water Content
The water content of a clay body is important because it controls its plasticity. Plasticity is the clay's ability to hold onto a shape that you give it. This allows you to throw a bowl, a pot or any number of other ceramics for pottery.
When you use clay that has high water content, it's a bit more challenging to work with because the clay tends to dry out quicker than lower water content bodies. As the clay dries out, it loses its plasticity and becomes harder to manipulate.
Clays that have low water content are a bit easier to work with because they dry out slower and retain their plasticity. However, they may not be as strong or durable as higher water content clays.
As clay moves through erosion processes, it can pick up materials that are not part of its original composition. These impurities are known as contaminants. These contaminants can affect the properties of the clay after it's fired.
When preparing clay for firing, the water in the body needs to be pure. Water that contains a lot of salts can negatively impact the final product. This is because the salts can cause the clay to crack or explode in the kiln. The best water to use is filtered and tested to ensure that it does not contain any electrolytes that could damage the ceramic.
