Spectrum’s mending paste is a ceramic slip that, when applied to either bisque or greenware and fired to earthenware or stoneware temperatures, will harden for a permanent fix.
Tax Excluded
Size: 118ml (4 fl oz).
Method
Cover both broken surfaces using a brush, hold together, allowing the slip to dry and harden. Then fire to the appropriate temperature.
Non-toxic and lead-free, therefore suitable for dinnerware.
The mending paste is recommended for temperatures up to 1240 (cone 6).
Best mending medium I've ever used.
As a crack fill, it wasn’t good - the bowl with a hairline crack that developed at bisque was filled but the paste shrunk significantly and the crack wasn't appropriately filled after the glaze firing.
On the manufacturer’s website, it says this product “does not develop strength until after it is fired”, however the pot label instructions say to "hold the pieces together until the Mending Paste sets sufficiently in place". The manufacturer instructions are the ones to follow - a vertical repair would be fine, sideways ones (e.g. adornments/decorations on the side of a pot) would fall off as it dries.
Product fires bright white, which would have been fine for me, if it didn't also shrink so much.
Images are from last week, earthenware glaze fired to 1100°C.
