Buying Guide

Lead-free glazes keep your ceramics safe. You won’t worry about toxins in your food or drinks.

I once fired mugs with an unlabeled cheap glaze. A fellow potter told me that glaze can leach lead into hot drinks. I threw those mugs out right away. Now I only use certified lead-free glazes for every project I make.

Factor: Safety Certifications
Always pick glazes with official safety approval. Look for the ASTM D-4236 label on the product. Make sure it is marked lead-free and food safe if you use it for dishes.
Factor: Firing Temperature Range
Check your kiln’s maximum temperature first. Pick a glaze that matches your kiln’s cone rating. Some glazes only work for low, mid, or high fire firings.
Factor: Intended Use
Decide if you make decor pieces or functional dinnerware. Only use food-safe glazes for plates, mugs, or bowls. Decor pieces do not need food-safe labels.
Factor: Finish Style
Choose a finish that fits the look you want for your work. Gloss glazes give a shiny, reflective finish. Matte glazes have a soft, non-shiny surface.
Factor: Ease of Application
Beginners should pick glazes that are simple to apply. Look for formulas that won’t run or bleed during firing. Most glazes work best with 2 to 3 thin, even coats.
Factor: Brand Reliability
Pick brands that offer clear support for their products. Look for warranties or easy return policies from the seller. Trusted brands test their glazes to get consistent results every time.
