JoLinDesigns Posted August 17, 2014 Report Share Posted August 17, 2014 Hello all!! I am having an issue with my small tiles crazing. Very fine lines are showing up after a month. I am using b mix clay to ^06 first then paint/glaze then firing to ^5. I have made over 100 triangular tiles. Can I glaze them again with clear glaze and fire to a low fire? Or are these trash!!!! Thanks!!! The crazing is actually pretty so I don't have a problem with it as far as visuals. My concern more so is the moisture issue.

Benzine Posted August 18, 2014 Report Share Posted August 18, 2014 Crazing is generally a fit issue, though it can be from cooling too quickly as well. Is this a commercial glaze, or one you made? A low fire clear, would help seal and smooth out the surface, over top the crazing. Though a clear, on top of the other glaze, can change the appearance of the lower glaze as well. If your clay vitrifies at Cone 5, then it should be non-porous, so moisture wouldn't be a concern. Though if they are used for food and drink, the crazing will leave places for bacteria to grow.

Mark C. Posted August 18, 2014 Report Share Posted August 18, 2014 There are so mant variables more details would help Heres a few is your B mix cone 5 clay? Is your cone 5 glaze homemade if so what is the formula? What is the final use of these tiles?counters or bathrooms?-decorations on the wall? what is your firing and cooling cycles?

JoLinDesigns Posted August 18, 2014 Author Report Share Posted August 18, 2014 Laguna B mix cone 5 clay. Mayco Clear Brushing Glaze. Speed medium/ Preheat 5 min/ Hold 20 min/ Cool @140 They are for a bar in a restaurant so moisture would be a huge issue!! I'm not having any problems with the stroke and coat glazes. Just the triangles where I use a velvet underglaze with the clear glaze. I guess I'll remake them using a stroke and coat glaze. We just liked the color of the other. I tried using Laguna's cone 5 glazes, but I really don't like the way they go on and fire. They just seemed so much thicker even when thinning, they thicken up again quickly Just hate to see these tiles/time/money wasted!!!!! Thank you!!!!
