Loved learning more about bone China. I collect bone China tea cups and knowing more about the history of the China makes it even more enjoyable to me. Thank you for all this great information.
Sir , thank you for valuable information. Though I have started collecting antique bone China tea cups recently, I never had any knowledge of it . Beautifully explained.
in USA 1932 Fly ash was first collected from coal fire stations then mixed with cement to produce highgrade structural concrete. Fine ash particles fill out the tiny air pockets in concretes. Air 'bubbles' that compromise the structural integrity of concretes
I have a set of NORITAKE CHINA JAPAN 5558 BLUEBELL ive been trying to identify if its bone or just fine china. Does fine china have 0 transparency? There isnt any info i can find online for that specific set and i can see a light behind it but it doesnt seem as transparent as your cups. Is there a transparency scale? Thank you for your expertise and help ❤
Unfortunately this video is inaccurate in a number of respects and the idea that the story can jump from Bow to Spode misses out most of the story. Here are a few additional (and in some cases corrected) facts: 1 Frye used bone-ash in a soft paste porcelain. The other materials used were not the Chinese materials which had been discovered in 1746 by William Cookworthy - these were not to be used in anger until 1766 in Plymouth and were protected both by patents and mineral leases so no other factories used them for many years. 2 Frye's bone ash porcelain was NOT durable. It could not stand boiling water so to find a teapot without a crack is most unusual. 3 Cookworthy moved his works to Bristol where it was taken over by Richard Champion. When Champion failed financially he attempted to sell the now somewhat ineffective extended patent to Staffordshire potters. The result of this was that the Staffordshire potters started to use the China clay and China stone from Cornwall for the fist time. They used other additives to reduce the very high firing temperatures and and fired twice instead of the single firing favoured by the Chinese. These experimental materials are now called Hybrid hard pastes and they were the backbone of English ceramic production from around 1780 to 1800. Frye's first (of two patents) in 1744 was actually for a hybrid hard paste body using frit glass and clay from North Carolina. It is generally accepted that the A marked group of porcelains were the result of this short experiment. 4 With many Staffordshire firms now having access to the hard paste materials there was much experimentation with additives to make lower firing temperatures and easier manufacturing possible. Several firms tried using bone-ash and it was Spode who perfected the technique. Whilst bone china has good translucency that is not an identifying feature as many hard paste recipes produce similar results and in some cases (e.g. Japanese eggshell wares) even thinner potting. 5 So the ten second story is that Bone China was a blend of the hard paste materials (used throughout many parts of the world) and bone-ash which had been used with mixed success in early English soft paste porcelains. To identify one man as the instigator of this story does a dis-service to the many firms that brought to Potteries to their ultimate height in the 19th century. However, if one person has to be chosen that one man would be Cookworthy, not Frye.
....but that doesn't mean that I agree with them particularly your comment about Cookworthy. And it would also be appropriate if you identified yourself and your expertise on th e subject!
Sir, this was an invaluable introduction to fine bone china. Thank you so much for sharing your knowledge! God bless you.
About as near perfect of a presentation as I've seen thus far. Informative, engaging, wonderfully paced, excellent all around! Thank you!
Thank you so mich for your comment
This was a fantastic video. Thanks for posting and sharing your knowledge.
Excellent information thank you

Thank you so much for that video! It was surprisingly engaging and very well-structured. I feel like ie learned a lot.
Thank you. Very informative and fun.
Thank you for the information.
Very very informative videos..... thankyou 😊
Thank you!
Wonderful

Thank you!!
thank you :)
Thank you for sharing
I never realized bone china contained up to 50% bone
