How To
How To Determine Metal Weight for Wax Trees
Knowing how to determine the correct metal weight for each wax tree before you cast ensures that you melt the right amount of metal for your cast, making your casting process more cost-effective and more reliable.

24KY = 19.32
18KY = 15.58
14KY = 13.07
10KY = 11.57
Fine silver = 10.49
Sterling = 10.36
Platinum = 21.54
Caster's brass chunks = 8.4
Caster's white bronze chunks = 8.1
Ancient bronze = 8.8
Yellow bronze = 8.4
Manganese bronze = 8.3
Nickel silver = 8.8
Alpaca = 8.6

Step 1  First, weigh your wax models along with main and gate sprues. Then add an additional 10% to account for your button.
Step 2  Multiply that total by the specific gravity of the metal you're casting (see table above for a general guideline).
Step 3  Example: For a 5-gram wax model, add 0.5 (10% of 5g) to get a total wax weight of 5.5g. For a 14KY gold casting, multiply 5.5g x 13.07 s.g. The amount of 14KY gold needed for this tree is 71.89 grams.

How To Evaluate the Effectiveness of Shrink Bands
Here is a concise comparison to illustrate how to evaluate the effectiveness of covering perforated flasks with Shrink Bands vs. other methods (masking tape and rubber sleeves).

• Easy and fast to apply
• Complete, waterproof, effective seal
• See-through
• Easy to remove
• Easy to apply
• Difficult to apply smoothly to flask
• Effective seal once properly applied (must be completely wrinkle- and fold-free)
• Becomes progressively less effective over time as elasticity deteriorates
• Difficult to remove
• Must be cleaned prior to re-use

How To Calculate the Cost of Firing Your Kiln
Learn how to calculate the cost of firing your kiln and discover how affordable it is and know how to more accurately price your jewelry items.

The cost of firing a kiln will depend on several factors, such as the charge assessed by the electricity provider, the power drawn by the kiln, the duration and makeup of the firing program being performed, the number, size and composition of the pieces being fired. Use this formula to calculate your costs.

Cost per kilowatt-hour (1)
x Kilowatt rating of kiln (2)
x Program duration in hrs. (3)
x Duty cycle of the kiln (4)
= Cost of firing program

(1) Providers of electricity charge for power in kilowatt (kW) hours. The cost per kW-hour ranges from approximately $0.10 to $0.20 depending on location. This rate is shown on the provider’s monthly bill.
(2) The kilowatt rating of the kiln can be found on the electrical data plate located on the side of the control box on the kiln. The data plate shows the volt, phase, amp and watt capacities of the kiln. Most smaller, introductory kilns that operate on 120-volt standard household outlets draw about 1500 to 1800 watts. Medium-sized kilns (17"–23"W) are rated around 5000 to 8000 watts. Some large glass kilns can be rated as high as 11,000 watts. To convert the watts shown on the data plate to kilowatts, simply divide the watts by 1000: 1500 watts = 1.5kW; 8000 watts = 8.0kW.
(3) The program duration is the number of hours the kiln fires to complete its program. This elapsed time is displayed on the digital controller at the end of the firing cycle. The firing time can be less than an hour or up to 20 hours, depending on the project. If the kiln does not have a digital controller, just measure the time from starting the kiln to when you turn off the kiln.
(4) The duty cycle for the kiln is the amount of time the elements are actively drawing electricity. Electricity is going through the elements ONLY when the relays are ON. The clicking or humming sound heard when the kiln is operating is a clear indictor that the relays are ON and the kiln is actively drawing power. Generally, the duty cycle for firing of kilns with controlled ramp rates, hold times and so on, is roughly 50%–60%. During a program that takes about six hours, the relays will only be actively on, drawing power, for about 3–4 hours.

In an area where the cost per kW-hour is $0.12, a small-sized kiln operates on standard 120-volt household power and is rated at 1700 watts (1.7kW). The firing program is a fast fusing of glass with a total firing time of 1-1/2 hours. A duty cycle of 60% (0.60) is assumed.
Putting this information together, the formula looks like this:

$0.12 cost/kW-hr.
x 1.7 kW rating
x 1.5 hrs. duration
x 0.6 hr. duty cycle
= $0.18 cost of firing program
Here is a table showing the firing cost for the same kiln and program at different costs per kilowatt-hour:

Cost/kW hr. = Cost of Firing
$0.10/kW hr. = $0.15
$0.12/kW hr. = $0.18
$0.14/kW hr. = $0.21
$0.16/kW hr. = $0.24
$0.18/kW hr. = $0.28
$0.20/kW hr. = $0.31

In an area where the cost per kW-hour is $0.12, a medium-sized kiln operates on 240-volt power and is rated at 7000 watts (7.0kW). The firing program is a basic firing for BRONZclay with a total firing time of 9.5 hours, including ramp and hold times. Again, a duty cycle of 60% (0.60) is assumed.

Putting this information together, the formula looks like this:

$0.12 cost/kW-hr.
x 7.0 kW rating
x 9.5 hrs. duration
x 0.6 hr. duty cycle
= $4.79 cost of firing program
Here is a table showing the firing cost for the same kiln and program at different costs per kilowatt-hour:

Cost/kW hr. = Cost of Firing
$0.10/kW hr. = $3.99
$0.12/kW hr. = $4.79
$0.14/kW hr. = $5.59
$0.16/kW hr. = $6.38
$0.18/kW hr. = $7.18
$0.20/kW hr. = $7.98

How to Choose An Appropriate Gate Size for Your Ring Patterns
Know how to design effective feed gates for your master ring pattern. A well-designed gate helps streamline the flow of metal into the pattern and helps reduce defects caused when metal can't effectively reach all parts of your pattern.

1  The main feed sprue diameter should equal
the sum of the two connecting gates for
optimal flow of metal into the pattern.
2  Balance the thickness with a single sprue of equal thickness, and there should be equal thickness everywhere.
Please Note: Round gates are best, and
3mm round is the best for most patterns.

How to Calculate NeuSprue Button Size To Reduce Metal Loss
When you cast with NeuSprue, knowing how to calculate the precise amount of metal you will need for your sprue button helps to minimize metal loss and use your precious metals more effectively.

1  The button portion of the NeuSprue™ has been economically designed to conserve metal usage while still supplying a needed reservoir of metal for the solidification process.
2  Because the NeuSprue wax button is hollow, the cast button will only be 1/3 full of metal.
3  To control the size of the button after casting, take the overall weight of your NeuSprue wax tree and subtract 4.7 grams (this will cast the tree without a button).
4  Then, simply add back the wax gram weight, up to 7.6 grams, that you want your final button to be. The full 7.6 grams will result in a full button after casting.
