usually not. the toughest engraving job, imho, would be certain firearms and custom knife blades. in the case of both, professional annealing and heat treatment are pretty much the order of the day. most all other metals are capable of being engraved without being annealed btw-- welcome to the...
natural chalk is the fosillized remains of billions of micro critters called foraminefera. very tiny shells made of silica. this would likely do the trick if such were harder than the ceramic.
a friend creates stuff that is difficult to believe. that is until you get it in yer hand. not sure of the software he uses. there's a site that has the software solution for an amazing aray of items already created. just waitin for download. i have been thinkin of buyin one of the printers just...
i think you should invest in one of the books on scroll design. you need to learn how best to fit design effectively in crazy lookin spaces. your basic spines look ok to me. it's simply one of making them work in a given shape.

i think it looks a bit awkward to do a symmetrical design in that shape. even though the design is symmetrical, it really is not in the constraint of the scale shape.
mike: somewhere i recall a video how you can re surface a ceramic lap. the video may have been by sam alfano. i checked youtube. there's info there on doing this. good luck
yeah. old fsshioned signmakers do that all the time. i even have an electrical pouncing device for doing very large layouts. sadly, is useless for engraving.
i've done a lot of glass etching. i have used the armor etch cream, i have used my 30 watt laser,as well as hand carved techniques. the etching cream is very faint imho. the laser aint much better. the granddaddy of em all is sandblasted effects on glass. followed perhaps with a bit of rotary...
welcome to the forum. the usa made tools are superior in every way to any of the knockoffs. the home brewed system by shaun hughes did work well for me. not as good as the usa stuff. the one i cobbled together would work for such as you seek to do. if, however, you will be earning money, you'll...
