Crackle glazes: varieties
Crackle glazes are available in a variety of colours and may be in matte, gloss or transparent varieties.
Dry Glazes
Dry: You can purchase commercial glazes in dry form, which are usually formulated for dipping, pouring, or spraying. In addition to a brush, you will need a bucket, some water, something to stir with, and a mask to avoid breathing the dust. The advantage of dipping is that you get a more even coating of glaze, and you can do interesting things you can't do with a brush, such as double dip to get different colours on the same piece. Spraying is usually done by more advanced people since it requires good ventilation, a gun, a compressor, a booth, etc.

A Disclaimer
Disclaimer: It is the responsibility of anybody using the above glaze recipies to be informed of glaze dangers and to ensure the proper safety precautions are met when mixing and using glazes. In general glaze components marked 'toxic!' should not be used for tableware. Other, not marked ingredients may be harmful to health on skin contact or if ingested. Frits may contain Lead Bisilicate. General safety precautions for ceramic materials apply. Contact a supplier, lecturer or professional if in doubt. Neither Lifetips.com nor its Guru, Jan, will bear any responsibility for incorrectly used glazes and/or ingredients, nor for any damages due to unexpected glaze results. All glazes should be tested before use.
Lead glazes
The label ”lead safe” does not necessarily mean that a glaze contains no lead, but it does meet minimum government standards for dinnerware items. A lead-free glaze means that it contains no lead at all.
