Types and Methods of Glazing
Glazes are made from a type of glass especially made in such a way that they adhere onto the pottery surfaces. When this glass is liquid it is stiff and will stick to the vertical surfaces of the pots when they are being fired. There are various ways of applying glaze.
The Dipping Method
The pottery is submerged into the glaze and this should be for around three seconds. The glaze is thick, almost like heavy cream and this one of the fastest and best ways to glaze large amounts of pottery and is a method that will ensure that the glaze goes on smoothly. When using this method preparation of your pots is important and this includes a good wax coating on the bottom. The glaze must be prepared properly; it must be stirred very well using a stick before so that no air bubbles get in before dipping. If the glaze is too thin you will need to dip it longer.
Glazing In and Out
The consistency should be the same for the dipping method and can also be done together with dipping. For glazing the interior of items pour the glaze in for about three seconds and then pour out. If there is excess glaze it can be flicked off or wiped off using a sponge or towel or if you prefer you can leave it as a decorative effect. You can also pour glaze on the outside of the glaze over the base layer. The two glazes may interact making the glaze more interesting, but be careful not to mix too many glazes especially if using multiple colours.
The Brushing On Method
Ready to use glazes are best applied with a brush and vary in consistency. Just like when you play games at River Belle casino, reading the instructions is important. This way, you know how many coats of glaze to use to get the correct colour. Commercial glazes are made so that the brush marks are smoothed out. Always stir the glaze well before brushing it on. Synthetic sables are the best brushes to use as they are durable and spring back well, always make sure they are washed after use.
The Sponge Method
Sponges are a great tool for any potter and can be used at each step in the process as well as applying glaze. For a basic application a fine textured sponge is needed, synthetic or natural can be used. If applying a 2nd layer, a contrasting glaze, a porous sponge will work best and the texture will create interesting patterns when being fired.
Spray on Method
Glaze can also be sprayed on using a spray gun or airbrush. Make sure that the nozzles that you use are big enough so that the glaze particles can move through without gumming up the nozzles. Spraying on glaze should only be done in a well-ventilated room in a spray booth. You should also always wear a dual-cartridge respirator that has been approved when spraying on glaze.
