Ceramic glazes in comparison (from Botz to Welte)

Have you ever wondered which ceramic glazes suit you? The decision concerns not only the appearance, but also the properties of the glaze. Powder or liquid? Stoneware or earthenware? Decorative object or utensil? These and other things you should consider when buying, I’ve written you a little together to hopefully make the decision a little easier.

But first I introduce you to our glazes manufacturer – including a small, colorful sample ;-).

Botz Logo

BOTZ GmbH was founded in 1984 by Mechthild Surmann and Jürgen Klück and has always focused on producing only liquid glazes of outstanding quality. Since the beginning, they have also focused on completely label-free products, i.e. primarily lead-free.

Botz offers a lot of inspiration and know-how on their website and social media, in addition to their wide selection of liquid glazes.

Which glaze is right for me?

Powder or liquid?

If you are completely new to the world of ceramics, the first thing you should consider is whether you want to work with powder or liquid glazes. Of course, you can choose both or experiment, but there are some things you should think about beforehand.

Powder glazes are not yet ready to paint. They still need to be mixed with water and additives. Mistakes can be made here, for example, by using too much water or too little additive. With a little time and practice, you will certainly get the job done, but if you want to do without it at the beginning, you are in the right place with the liquid ceramic glazes!

With these you do not actually need to do anything more, so you can apply them immediately to your work, because liquid glazes you get ready to paint from the trade.

Earthenware or stoneware?

Next, you should consider whether you want to fire in the earthenware or stoneware range. Both have their advantages and disadvantages. With stoneware glazes, for example, you have less choice, although there are many more glazes available in this area today than in the past.
To make your decision a little easier, I have written down some application areas and information about the respective ceramic glaze:

Earthenware glazes usually do not burn out tightly during glaze firing, so predominantly you should use your work as a decorative object or if you make a drinking cup, use a different sealing method!
Unfortunately, these glazes are not frost-proof, so if you are making stelae, birdbaths, etc. for the garden, you should definitely bring them indoors or into the cellar in the winter.

Stoneware glazes, on the other hand, are particularly suitable for the production of densely fired works because of their high firing range. This means you can leave water in bowls or planters for a long time after glaze firing. Ceramic glazes are also particularly suitable for floor and wall tiles, both indoors and outdoors.
Furthermore, you can safely put works with stoneware glazes in the dishwasher or leave them outside over winter.

Ceramic glazes with effect

Glazes with crystals, different patterns and lines, craquelé and metallic effects are extraordinary and beautiful to look at. Nevertheless, they are not suitable for certain works, such as utensils. Here the above mentioned are all out of place, because cracks in the glaze let liquid through to the clay, metallic effects and patterns in the glaze contain substances or crystals that react with liquids or acid.

Utility ceramics

Two points above I have already introduced you to the glazes that are not suitable for utility ceramics.
So here we go with the suitable ones: Most of the time you can’t go wrong with plain glazes, especially white ones.
Nevertheless, you should always ask for a safety data sheet in connection with utilitarian objects. You can also do a little acid test if you’re still not sure:

Make a sample with your glaze on a piece of clay and burn the whole thing. Then place a slice of lemon on the body overnight, or for at least 8 hours. If the glaze does not change you can use it in private use for plates, mugs, etc., if it does change you better not use it! (all commercial consumers need a certificate from a laboratory!).

Basically, you can take any glaze on the outer wall of the mug, the upper rim and the inside you should definitely paint with a food-grade glaze. For liquid glazes, BOTZ and CHRYSANTHOS provide information on suitability in this regard!

Conclusion

So you see, finding the right glaze is not so easy if you want to design certain things or you are completely new to this world. Basically, it is especially with the ceramic glazes and clay recommended to consult your trusted ceramics supply, because here you learn much more things that are not written down on the Internet and sometimes even get tips from their own experiences. Nevertheless, I hope that you could take a little of my tips and always look forward to your suggestions! 🙂

On Instagram I also show you weekly glazes from the above manufacturers that we carry in the range:
