How the ceramic coating is done?

The ceramic coating can improve the decorative and functional qualities of clay work. Ceramic coating is also known as ceramic glazing. Glazes can effectively seal your clay bodies after they've been fired, making them watertight and food-safe. So, how do you get the coat onto a pot after it's ready to be coated? From dipping to brushing, here are the most popular techniques for applying glazes to ceramics.

How to start glazing your ceramics?

Generally, glazing ceramics entails preparing glazes, putting a glaze on bisque-ware, allowing it to dry, and then loading it into the kiln for glaze fire. The kiln is gradually heated to the proper temperature for the silica in the glaze to melt, then gently cooled. This strengthens and solidifies your pottery, making it impenetrable to water. So, let's take a closer look at the various coating processes for your ceramic:

Dipping

Dipping is the simplest approach to covering pottery in the glaze. It can be used to either finish the base layer before decorating or to apply a solid color that will not be designed, in each case you may need to dip more than twice until your glaze reaches the desired thickness.

Process:

  • When dip glazing, it's usually always a good idea to make sure your pots are thoroughly prepped, including a nice coat of wax resist on the bottoms.
  • The longer the pot is dipped, the thinner the glaze texture is.
  • To begin, use tongs to hold the clay piece.
  • Slowly drop the piece into the glaze, being careful not to cause any bubbles or splashes.
  • After you've removed the object, give it a quick shake to make sure there's no leftover glaze.

Pouring

Pouring is the ideal option if you're coating the insides of your pot. Dripping is another term for pouring. It's commonly connected with pouring during designing, with a solid-colored coating covering the entire object.

Process:

  • Allow about 4 seconds for the glaze to rest within the clay piece.
  • After that, swiftly pour the piece back into the glaze container.
  • Any remaining glaze can be scraped off with a rapid twist of the wrist while maintaining the pot's edge parallel to the ground, wiped away with a sponge or cloth, or left alone.
  • Glazes can also be applied to the pot's outside surfaces. This is frequently done to apply a thinner glaze coat over a foundation layer of glaze.

 

This dripping technique may also be used to embellish pottery. Simply use any squeezable bottle to create your creations. Dripping creates a striking texture, especially when combined with contrasting hues.

Brushing

Many ready-to-use glazes have been designed to be applied using a brush. They usually have a higher viscosity than dipping glazes. They also have glue in them that prevents them from slipping off the pot once applied. Make sure to read the directions thoroughly since they will tell you how many coats to apply for the desired hue.

process:

  • Apply a generous quantity of glaze to the brush.
  • Try sweeping a big space in a single motion.
  • Reapply the second coat when the first has dried.

The glaze should preferably be applied with a bigger brush that can contain a lot of glaze. Synthetic sable brushes are the ideal brushes for this purpose. They're both tough and can bounce back after a lot of wear. After each usage, thoroughly wash your brushes.

Spraying

A light mist of glaze is sprayed onto the pottery while spraying the glaze. This is a superb approach to having a uniform glazing application. It's also useful for making a gradient between two glaze colors. Spray guns and airbrushes are two common pieces of equipment used by potters to apply glazes to their work.

Process:

  • Glaze particles must be handled with nozzles that are big enough.
  • Begin by thoroughly blending the glaze ingredients.
  • Placing the ceramics on a banding wheel is a good idea. While spraying, keep the Banding Wheel spinning and the spray cannon steady.
  • Wait a few moments before adding another layer.
  • Don't wipe the wet glaze; any mistakes can be fixed once it's dry. Keep an eye on each glaze layer's thickness.
  • Despite the fact that the spray booth will remove the majority of the glaze mixture, you will still need to wear a mask. This will assist you to avoid breathing any residual glaze particles from the air.

Kiln method

  • keep your bisque-fired piece clean and dry.
  • Make sure your glazes are thoroughly blended. To maintain a smooth consistency, make sure the heavier silt is well mixed.
  • Now you can glaze your ceramics by dipping them in it, pouring it on, or brushing it on.
  • Before adding a layer of glaze, which seals and waterproofs the ceramics, you can use underglazes to add color and design.
  • Two to three coats are recommended.
  • Before putting your piece away to dry, make sure you wipe off any glaze from the base.

Firing the glaze:

The glaze should be fired according to the manufacturer's recommendations. Low-fire glazes are burned at 1845°F, whereas mid-fire glazes are fired at 2192°F, and high-fire glazes are burnt at 2305°F.
