Glass / Re: Familiar objects but where when and who?
« Last post by Fuhrman Glass on Yesterday at 04:41:00 PM »found a reference to "end of Day" in a book 1966 Glass Paperweights of the Bergstrom Collection. It stated it was was much like "macedoines". Lots of random chips or cane pieces that were used to make pieces randomly at the end of the production shift. These were normally strewn on the marver and rather than sort them or swish them away, they gathered them into a "conglomerate" of color.
I personally have done this many times as I may have used many colors of frit in a day making numerous pieces and at the end just pick a lot of them up together and make something of them.
Other books mention this technique using just 2 or 3 colors of frit decoration a being "mottled".
I think the splatter/splotches term has come down from the ceramics trade that used this technique for decorating and it was literally splattered glaze on the piece of ceramic. many times done with flipping a brush full of glaze at the piece or sometimes done in other ways.
The risk in actually combining all of these colors is that many will crack eventually because they have glasses that are not compatible with each other, i.e. different COE's, or different viscosities that don't allow them to adhere to one another correctly. Some shapes are more forgiving of this than others and will keep the glass under tension or compression and give better results. Some glasses will actually change their COE's dramatically every time they are reheated in the glory hole. Looking at some old glasses under a polariscope will show stress that you'd wish you'd never seen. Many new pieces will exhibit some of the same tendencies as well. Combining multicolors is not an easy process. Opaque colors, reds, oranges, pinks, yellows are the most notorious for not matching others. I have some pieces in my collection that I've had over 40 years and have noticed just recently that they have finally cracked. they may be 75+ years old or more.
I know, more info than you ever wanted for a small "rose bowl".
