{"product_id":"example-of-pinholes-on-three-cone-6-clay-bodies","title":"Example of pinholes on three cone 6 clay bodies","description":"This was a fast firing. The glaze is G2934, a silky matte. But that does not mean it is pinhole-prone, it has good melt mobility. The clay on the right is Plainsman Coffee Clay. It contains 10% raw umber, that generates plenty of gases during firing. The centre one is Plainsman M390, not normally difficult to fire defect-free. The left one, M332, should be the worst, but is the best!  What is needed to fire these without pinholes? The drop-and-hold and slow-cool C6DHSC firing schedule. It is extra effort to program your kiln controller, but well worth it. If you don't have a kiln controller then by a little experimentation you can develop a switching pattern to produce the same effect.","brand":"Synapse","offers":[{"title":"Default Title","offer_id":35160812453933,"sku":"","price":0.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0016\/9017\/3485\/products\/xiekbptp4q-400W.jpg?v=1613407493","url":"https:\/\/flying-mate.myshopify.com\/products\/example-of-pinholes-on-three-cone-6-clay-bodies","provider":"Synapse","version":"1.0","type":"link"}
