  1. That defendants do not produce in their flow-tank "streams" composed of clear and of different colored glasses; but defendants only produce bodies of clear and colored glasses, irregularly mixed and constituting gobs of the old style, or prior art gobs, in form or character; and defendants' marbles do not have the colored glass on the inside only, within the clear glass, but defendants' marbles have the colored glass on the outside and scattered all through the clear glass, irregularly.

  2. Ive just had a little look around google books and come across this article

    i think it pretty much spells out marble production in germany in the 20s at least traditional production anyway

    Makes me wonder how long the transitional period lasted

  3. Im a bit lost with this one so any thoughts appreciated its spot on 21/32 Bit of an observation the glass may have been pretty cold and the marble hasn't smoothed out in the rollers as the heavier white is a little proud and in some spots i can catch it with the finger nail

    and may explain a little the ruff as guts seam ?

    Thanks

  4. Gave this one a run through the ID section a year or so back when i dug it with no real result i think due to my description and pictures

    Since then and in particular over the last couple months ive been liking the striped transparent types and have managed to snag a few on ebay and with all the CAC action recently ive been comparing some of my Mibs with similar patterns

    Well ive all but convinced myself this one is CAC What do you all think just a shade under 17mm or 21/32

    White strip traveling around to other side of seam is also one part of S pattern

    Thanks

  5. Although the principle is the same two opposing steel halfs the codds stopper marble mould was much different to the lead bullet mould it was circular and moulded 16 at a time

    Below is a picture showing the moulds , and sprig belonging to John Ault and used for education

    the lad to the left is holding what has come out of the mould i believe it is called a sprig the marbles were broken of and the ruff ends were if long manually filed off and then the marbles ground down in the machine below

    Here is a small part of an article written by Mark Potten Credit to him for the pics and article

    The plunger having been released, and the mould opened, the boy seizes the centre of the glass, now cooled to a semi-liquid, and runs off with it to the annealing oven, where he knocks the marbles off into a large iron box, to hold, say, 100 gross, sufficient for a day's work. They are there left to anneal thoroughly, and are then cooled gradually and taken to the grinding-room where they are carefully sorted, and those that have been broken off with pieces, too long for grinding are chipped first.

    The best way to do this is with a file having a countersunk hole in it, into which the “get” or burr of the marble is placed, a small half-round file being used as a chopper. The marbles are then ready for grinding, which process is best accomplished by the use of Mr. Wickham’s grinding apparatus. This consists of a grindstone, working horizontally on a vertical shaft. The stone is placed and made fast to an iron table, and an iron bar is laid across the top, which keeps the surface smooth. Four boys can work at one grinding machine each being able to grind, with the use of the Wooden holders supplied by Mr.Wickham, about two gross an hour.

    Water of course is used, and the waste is allowed to pass off through the curved pipe shown under the grindstone. When the burr is ground quite smooth and even with the rest of the marble the operation is completed. The counting is accomplished by an ingenious shovel with twelve grooves, each groove being made to hold a dozen marbles so that every time the shovel is used in counting one gross is scored They are then sent in boxes or casks to their destination. “

    Hope this is of some interest and adds to the thread Presumably your marbles could have been made like this in large numbers
