![]() You might choose to layer up two flowing glazes. Very simply, melt fluidity is how liquid or fluid a glaze becomes when it melts. Also, the glazes may have different melt fluidity. Glazes with different levels of opacity and color can interact with interesting results. It can be a lot of fun to experiment combining different glazes on your piece. Different glazes can interact in surprising ways, and create beautiful results. It is fine to use different glazes for different layers. If you are brushing your glaze, you may need to apply 3 or 4 layers of glaze. However, you may need to thin the glaze down by adding water, so that multiple layers are not too thick. If you want to combine two colors, you can dip a second time into a different glaze. If you are dipping your pottery in glaze, one dip is usually enough. And, you can let the different glazes run into one another too. You can apply different glazes to different parts of the pottery to set up a contrast in colors and tone. Glazes can be combined on raku to good effect. If you use crackle glaze, the cracked areas of exposed clay will carbonize during reduction and turn black.The dense matte black finish can provide a very attractive contrast to colored or metallic luster glaze. If you leave areas of the bisque unglazed these will turn back in the raku process.Apply about 3 or 4 layers of glaze and allow each coat to dry in between.Apply a generous layer of glaze to ensure that the pottery is covered well.This is because the water from the glaze absorbs into the bisqueware. The first layer of glaze will try quickly (usually in a matter of minutes).You can easily wipe this off with a damp sponge or cloth. If you get glaze onto the foot ring, don’t panic. Otherwise, the glaze will melt onto the shelf. In this case, you just need to avoid getting glaze on the part that will sit on the kiln shelf. You can simply brush it on from its container.Īs with glazing other pottery, you should avoid getting glaze on the foot ring of your pottery. There is no need to adopt any particular approach.īrushing is a popular technique because you don’t have to have a large quantity of glaze in a bucket. Techniques can include dipping, brushing, spraying, and sponging to name a few. Glaze can be applied to raku pottery in the same way it can be applied to other bisqueware. How to Glaze Raku Pottery – Applying your Glaze However, if you want a more predictable result, a raku glaze may give you that. Not knowing how your glaze will turn out is part of the charm of raku. This glaze may look very different when it has been through the post-reduction process of raku firing. Nevertheless, if you are new, you may want to get a handle on using low fire glazes first.Īn ordinary low fire glaze would normally be fired in the oxidation atmosphere of an electric kiln. This approach means that you are not limited to using lower fire glazes. When the low fire glaze melts, it encourages the underlying high fire glaze to melt too. One technique is to apply a low fire glaze on top of the high fire glaze. ![]() ![]() Some potters state that you can use mid and high fire glazes on raku if you adapt your approach ( source). However, this is an opportunity to tweak your approach and try again. It may not look how you intended it to be the first time around. Sometimes the only way to know what a glaze will look like is to try it out. However, because the results of a raku fire are quite unpredictable, it is the ideal chance to experiment a bit. Consequently, it’s a good idea to choose a low fire glaze. The important point here is that the glaze needs to be able to melt at lower raku temperatures. The pottery is then removed from the kiln and various post-firing steps are taken. In raku firing, the aim is to get the pottery and glaze to a temperature where the glaze has melted. Typically, a raku firing will be between cone 010 and 06. That means that although the pottery becomes red hot, the temperatures reached are relatively low. The key thing to remember about raku firing is that it is a low-fire process. What Type of Glaze to Use on Raku Pottery ![]() However, if you are using glaze, then the first thing to know is what type of glaze to use. There are numerous different techniques for decorating your raku, some of which do not involve applying glaze.
